Hi there is it possible to convert 4h trans to a 7h trans if so then how.
thanks

4hdd sounds like a early VR trans, the 7hdd trans would be late VS and early VT if i'm right.

unfortunately they aren't interchangeable because during the late VR models there were changes made to the trans, there was a extra solenoid added in the valve body and a extra wire in the loom. or something along those lines anyway.

welcome to JC by the way
