Hello Everyone,
About 2 years ago I rebuilt my 700R4 automatic trans in my '88 Chevy blazer s-10 4x4. As I was completing the job, my brother mentioned to me that I should put Mobile1 ATF in. Unfortunately he had meant natural Mobile1 whereas I bought synthetic. Obviously synth. is much more expensive and not what my 700R4 was really designed to be using. The big question is, can I switch back? If so, is there anything that I need to do other than dropping the pan, draining and a new gasket?
TIA, Joe
