Did you not read my post? I said valve body, harness, trans cooler fittings. Been there done that 9 years ago.
Iirc the bell housing thread sizes are different for those cooler fittings as well. I deleted my factory lines and went full braided cat hose and jic fittings.
I did, but the statement that they are all different is incorrect. There are various differences based on the year/model. That is the point of my post. Depending on the configuration of the trans the OP uses, there will be varying things that would have to change.
Correct, the thread size is different and the actual line itself is different in terms of the collar/inserted length. If the OP is not going to use aftermarket lines, he needs to buy the appropriate adapter fitting set from GM (they're $20-40).
