Nice kit only 1 issue with it though.

The kit is very nice and i use it for my 2.0 LSJ to a 700r4. However, the bell housing adapter plate covers up the oil cooler holes so you either have to cut the adapter plate or get creative with your oil cooler set up. Not a big deal but other than that everything works perfectly fine.

We are sorry to hear of this issue! I will be sure to bring up the covering of the oil cooler at our next meeting.
