Hey guys so my truck is a 93 C1500.
So this has been going on for several years now.
Anyway, when i first bought the truck it did not shift hard, but after several months it started doing it.
So, within a year we replaced the trans with a new one from the factory and it still did the same exact same the same way. It's been doing the hard shift for years now.
Basically its like a laggy shift..? it jerks really hard when it lets go of first and picks up second. It makes my whole dash shake and my flip up head unit almost smack itself. It is completely random when it does it, but usually happens 75% of the time. Weather independent, engine temp independent.. just completely sparatic.
So with all of that, what could it be? I mean it's a new trans (well not new anymore) and it still does the same exact thing it did with the old one. Someone mentioned to me i might want to try another ECM and see if that helps anything.
Any advice or somewhere to start?
Thanks in advance.
