I have an 1989 IROC 5.0 TPI 5 speed manual trans that bucks when I go slow around turns or just slow for the gear that I’m in. I can’t make a turn without downshifting into 1st gear and then it still bucks. Very annoying. Any ideas?

 

Rear end might need service,might be someone changed the oil in the diff without adding posi-lube.

 

Thanks for your response. I never thought of that. It has always bucked since I owned it but it is getting a lot worse.

 

Check all your motor and trans mounts too.

 

Thanks will do.
