"I am totally impressed by the design and machining on these pieces. I was a certified tool-and-die maker for seven years and have three degrees (BS, M. Eng, PhD) in mechanical engineering along with a Professional Engineering license before becoming a medical doctor. It takes A LOT to impress me. Your products are excellent. I have several other old classic cars I want to update to modern transmissions as well..." - Jeff J., M.D.

"I refer many people to your product as I have personally used the PA kit and experienced several of the PA design faults on my own Bronco. Thanks for your prompt reply. Looking forward to using your kit on my other Bronco." - Brian C.

“Impressive Kit…Ordered this kit after ordering a competitor kit that didn't work with the 5.0 6R80. The quality of the pieces is superb! Easily the prettiest parts on my truck! I was also impressed with the Tetris-style packaging. Everything was held firmly in place and the heavy duty cardboard kept it all protected. Great Product!” – Brandon P.
“…Thank you for the great Communication. I will sing your praises on the early bronco forum. I am Putting mine in an early bronco with an atlas TC. Appreciate the awesome communication.” – James K.

"Hi, All I can say is ‘wow’. The bellhousing arrived today. I’m super impressed with the quality, and the unbelievably fast shipping. The engine and box are in the car, with the old bellhousing. I’ll take it apart this weekend and let you know how it goes. Thank you for your great service!” - Alistair Davidson, NZ Petrolhead & NZ Rodder
"I spent a a lot of money, trying to get the hydramatic transmission to function. What a lose of time and money that was. On thinking of rebuilding trans. , AGAIN, my son came up with speed gems when we were planning our next move with the 50.What a relief that became on getting this project on the road again. To the scrap yard went my three boat anchor hydramatics, in went a early 350 turbo. wish i had an overdrive to put in, but you work with what you have.I can't express my thanks to speed gems enough for their kit, everything went together without any problems. I highly recommend their products. Wouldn't hesitate to use them ,on the next project” - Frank
"Both packages arrived… The purchasing and notification process was excellent. Thank you!” – Charles Wilson
"1957 Olds 371 - I have 2 different styles of these adapters on 371 Olds THIS ONE WAS #1 perfect fit. They stand behind there product! The starter fits the block with headers! Thanks!" - Ed
"1964 Olds 394 w/700R4 in '35 Olds - I bought this adapter kit 8 years ago and finally finished the car. All parts of the adapter are a perfect fit. I had the rotating assembly balanced (external balance), minimum weight added or subtracted. NO vibrations up to 5000 RPM. Great high quality product." - John C.
"It was exactly what we were looking for, and the cool part is that this Y-block adapter will mount an AOD, C4 or C6 to your Y-Block. Of course, the proper flexplate must be used for each of these transmissions, but it is a very versatile adapter plate. We opted for the AOD to Y-block arrangement, and for our $700 we received one very nice machined adapter plate, a new high-torque starter, a crankshaft adapter and a new flexplate. Also included in the kit were all the mounting bolts. The kit isn’t cheap, but it is complete, it works, and all the parts are well machined." - Street Rod Builder
"I ordered one of your kits about a year ago and wanted to take a minute to thank you. The kit was way more than I could have hoped for. Everything was top notch. What made me think about you was on a car forum. There were some other guys on there talking about your kits. I wanted to let them know how awesome it is. I know personally after installing the adapter plate (maybe 5 minutes) the transmission was probably the easiest install I ever had. As a matter of fact I took it back out because I thought I was doing something wrong, because it was just too easy. Thanks Again." - Justin Moore
"The transmission adapter from Bendtsen’s worked perfectly when I mated a T-5 transmission to a 324 Olds engine. If you need a transmission adapter check with them. Thanks again to all involved!" - Jimmy Hervatin
"I just received my parts that I ordered and wanted to tell you how VERY pleased with the quality I am. Everything fits perfectly. It’s nice to see that some people still take the time to produce quality items. We will be doing more business together, thanks!" - John Treharne
"I will say, beyond the fact that I prefer your steel adapter and the use of an OEM flywheel, your customer service is terrific! Thanks for providing me with the info I need to make solid decisions and word of mouth promotion. Thanks again for your time." - Jim Denison
"The kit as supplied by Bendtsen's included an aluminum adapter plate, a new high-torque starter, a new flex-plate and a crankshaft extension. The parts are all high quality and as we were to learn later in the operation, they fit together perfectly." - Alan Mayes, Car Kulture DeLuxe
"Hello, I purchased your AOD - Y block adapter and I am very happy with the quality. It is well worth the money. The machining is perfect." - Shawn Bremerton
"Your site is probably the best I've ever been to! Being a FE/Mel fan (also 534/Transmatic) aficionado, I am a little biased when I find someone with obvious similar thinking. Excellent photos of the FE 427 '65 to '70 Ford big car cast headers, the most beautiful iron castings I've ever seen. Thanks for everything, keep up the good work." - Dale Zalaoras
"Hi, Adapter arrived today. IT looks great. Maybe to good looking a part to hide between the engine and transmission, and shipping wasn't more than 6 weeks. Thank you for the great service." - Tomi, Finland
"Bendtsen's, I wanted to tell you that the work you have done for us is some of the best I've seen--very thorough and professional. Thank you again for the fine work." - Randall Murray
"Adapter arrived safely today. Many thanks, it looks fantastic! I'm chasing up a Hydramatic flywheel now and hopefully , will soon be able to fit it up to the box, do the floor/trans tunnel etc. Again most appreciative of your efforts, it's great work. Best regards." - Wayne, Australia
"In August, I purchased an adapter to mount an AOD transmission to a Y-block V8. The process of completing this car has been slow. I had to install the engine and transmission in the car after the engine compartment was restored but before the body was painted. I am currently completing the interior and am anxious to drive my new ride. The started was connected to the adapter plate. All the bolts were provided and the instructions were very specific. I had no trouble making the connection and adaption went very smoothly...
While the modification to the frame was not "Bendtsen's" responsibility, you were very helpful in the pointing me in the direction of where modifications needed to be performed. After mocking up the transmission/engine combination in Styrofoam, I was able to determine the cut/bends and general tweaking that needed to be done. I truly expected to have to insert the trans/engine at least twice before achieving a desirable fit. To my surprise, the assembly went in the first time and I did not have to remove it for additional modifications. My project is a 1956 Thunderbird. I am using the original shifter and I have "timed" it to the AOD. Other than the plate used to make the conversion, it is very difficult to determine modifications. GREAT JOB Bendtsen's!" - Larry, Oakland, MI
"I bought one of your '57-63 nailhead kits to put a turbo 350 behind. Just to let you know, I pulled it all together today. Put it in there and ran it and your kit fits like a glove. You don't find that too often. I built quite a few street rods and some of the units you have to be modify. It worked great, thank you!" - John, Tomah, WI
"Our early research indicated there was no kit on the market for this combination, but then after doing some research, we came across Bendtsen's Transmission Center. After a brief discussion about its new adapter plate and the obligatory passing of the plastic numbers, we had an adapter kit coming our way. It was exactly what we were looking for, and the cool part is that this Y-block adapter will mount an AOD, C4 or C6 to your Y-block. Of course, the proper flexplate must be used for each of these transmissions, but it is a very versatile adapter plate. We opted for the AOD to Y-block arrangement, and for our $700 we received one very nice machined adapter plate, a new high-torque starter, a crankshaft adapter and a new flexplate. Also included in the kit were all the mounting bolts. The kit isn't very cheap, but it is complete, it works and all the parts are will machined." - Street Rod Builder
"Bendtsen's adapters are amazingly comprehensive line that have just about every obscure motor that you'd want to show off spoken for. From Y-blocks to nailheads and almost everything in between, a complete adapter kit can be ordered and installed by anyone with two wrenches and brain cells rubbed together." - Doug, Garage Magazine
"Just wanted to let you know I got the kit. I test fitted everything last night, all looks good. The parts look outstanding, even showed them to a friend who builds hot rods for a living he was very impressed. Thanks again, look forward to getting this vehicle on the road." - Garry, West Palm Beach, FL
"Bendtsen's, thank you for the great service. I received the adapter kit for my Nailvalve to 700R4 transmission; it appears to be of top quality and very well thought out. All of the parts except the torque converter drive plate have been installed on my engine. The drive plate needs to be painted, and I will not install it until the engine is actually being lifted into place to not risk damage." - John Codman, Waltham, MA
"I ordered one of your kits about a year ago and wanted to take a minute to thank you. The kit was way more than I could have hoped for. Everything was top-notch. What made me think about you was on a car forum there were some other guys on there talking about your kits. I wanted to let you know how awesome it is. I hope that I did a decent job of it. I know personally after installing the adapter plate, the transmission was probably the easiest install I ever had. As a matter of fact, I took it back out today because I thought I was doing something wrong because it was so easy. Anyways, thanks again." - Justin Moore
"Bendtsen's, I have been meaning to drop you a line about the Lincoln Y-block adapter...I am way impressed. Well thought out design, flawless operation, and great fit! I was able to install it in my '55 with minimum fuss and effort. Top notch kit as far as I am concerned." - James Doss
"Bendtsen's, I just wanted to say how amazing your product is! I installed the trans adapter for my 1949 Buick Super 50 convertible with a 248 straight 8 and was extremely happy with the time, engineering, and finessed that was put into creating your transmission adapter. I would HIGHLY recommend this product to anyone interested in hassle free trans upgrade. Thanks SO much for your ingenuity." - Frank Spatacco
"Received a kit about a month ago and got my car back from the shop today. Gone is the Slim-Jim and a 2004R is now in it's place. What a pleasure to drive. Probably the single best thing I've done to the car in all the years I've had it." - Mike Anderson, Colorado Springs, CO
"Bendtsen's, nice kit for the 312. Having done several similar projects over my 50 years of cars I am qualified to say so. Don't often buy aftermarket parts that impress me. Is this plate drilled for the FE also? (yes) The trans on my wheelie car is on a gearbox at the rear of the chassis that I fabricated in '92 and still flawless. This car consistently runs 8 second 1/4 miles at 150 on 2 wheels. Thanks." - Danny O'Day
"Bendtsen's crew, just wanted to send my compliments on the adapter I bought for my Packard straight 8. It REALLY woke the car up! You can use me as a reference anytime. Thanks." - Joe Hallowell
"I just thought I would drop you a quick note with some feedback on my latest purchase, the Mercedes to GM adapter kit. I have just one word...awesome! It fits a treat and I have not been able to put the thing into the Gelandewagen yet as I keep on having friends come over wanting to see it. Thank you very much, your products are just awesome! I spend many hours on your website dreaming up new conversions!" - Thinus Strydom
"I installed the adapter in my 56 T-Bird about a year ago and let me say this, IT IS THE BEST MODIFICATION I COULD HAVE DONE. Anyone who has driven a 55-57 Thunderbird at Highway speed knows that at around 70 mph that poor engine is turning 3500 rpm or so. Even rebuilt, that is hard on a 62 year old engine, not to mention fuel economy. I changed the Ford-O-Matic out and put in a rebuilt 86 AOD transmission. The kit was complete and the machine work is beautiful. The installation instructions were easy to follow and the modifications were simple. Now at 75 to 80 mph it runs around 2400 rpm. Even low end performance from the start, all the way through the gears(4 of them by the way) it is a vast improvement. If you bought that classic to drive and you weren't looking for a garage Queen, then I HIGHLY RECOMMEND this mod. Thank You Bendtsen's" - John Clark
"Received conversion kit today. Quality exceeded my expectations and complements to your shipping people- arrived in as packed condition. I will be ordering other components to convert to T5 soon." - Pat
