You should change the thread title since your problem is not related to GM Synch FM.

 

It is my bad, it was late last night and I wasn't thinking very well.

I mean I like GM SMFM better than OEM fluid and Mobil1 Synthetic 75W90 better than LE607. Since I had GM SMFM in tranny and Mobil1 Synthetic 75W90 in diff, I have no problem with first gear pop out any more.

I am sorry for the errors.

 

Yes, definitely change the title of the thread, you are giving lots of other people the impression that the fluid is crap when that is definitely not the case

It is the first fluid change of any type that I saw a practical improvement and not just a theoretical or potential improvement.

 

Update...

It was a broken spring retainer on the FD



Tranny shifts like butter now

 

Dumbass.....i told you it was the FD spring retainer....

 

lemme dig up that msn history and confirm...
