So i only got 1st and 2nd gear in my 1990 silverado, and the tranny seems to shift into neutral after 2nd. I've had a couple of guys tell me it sounds like the 3-4 band is toast along with clutches. I just rebuilt the engine in this truck myself, massaging every part myself (within my budget). Now that the tranny took a , well it just sucks so I want to fix it of course. Any information on this topic would be greatly appreciated. I'm a pretty good DIY kinda guy so I'm lookin to do this myself.

 

You have a 3-4 clutch failure or broke the snap ring groove in the drum for the 3-4 clutch pack.

 

Listen to this man. He speaketh the truth.

 

thanks for the quick reply guys. do you think this is something i could attempt to fix myself? will it require dropping the pan, or pulling the whole tranny?

 

3-4 clutch is inside the tranny.....lot more than just dropping the pan.

 

Time for some more noobster questions.

I'm thinking about tearing it down just far enough to replace the 3-4 clutches, and throw in a shift kit, just basically get it back up to snuff as cost-effectively as possible.

What I would like to know is all of your opinions/advice on this. As I've said before I know very little of Auto-trans, but I want to learn.

Thanks in advance

 

There's a lot more to it then just replacing clutches. Yes the shift is pretty easy but clutches is a whole different story. Basically you have to remove everything, the pump, plantary, etc. I've done multiple shift kits and servo installs. This is one that if your a noobie do not need to tackle without some help like a manual, personal help, etc. You have clearances and everything else to deal with. Plus, if your in there, you might as well replace a few more things b/c no telling what else the 3-4 pack took with it when it went out.

Remember, keep everything as clean as possible.
