1997 chevy blazer awd - no reverse and slipping in forward - oil good no leaks - whats this?

Sorry to say but I think you are infor a rebuild or new transmission.
Talk to a trans. shop near you and get their input...

Does it have a automatic or manuel trans? You said gears, manuel trans, possible shift fork, syncro, anyway you will need
some serious work done to it....rebuild it or replace it.....

Transmission is done. Nothing electronic will cause that, only mechanical

I'm sorry to say this but I don't want to lead you on that it is a simple fix.

Your transmission has a major internal failure. You either have a clutch pack worn out or a stripped out sunshell.

This will be an internal transmission problem.
Transmission mountings or seals broken or leaking.
Rear band broken or worn.
Rear band apply pin or piston to short or binding in case.
Low fluid pressure.
Direct clutch components worn, jammed, cracked or leaking.

It will probably need an overhaul or replacement. Sorry.

Well a good place to start is to check the fluid ,Engine running in park.If the fluid is full then you may want to service the fluid and filter,dont use one of those fluid flushing machines they dont clean the filter reguardless of what the guys says(it is inpossible to reverse flush the filter.If this does not help there are two places that could be a problem.First and somewhat easy is the overdrive servo piston.Forward clutch oil pressure is used as the release oil and a hard rubber seal on the piston can cause this problem.If you want to atempt a repair i can walk you throught it .The other and most common problem is wear on the forward clutch sealing rings.They were changed in this year model from cast iron to brass and the brass tend to wear faster.They have since been updated to nylon.This will most likely mean a rebuild because it will require the transmission to be disassembled.

I have a 1995 Chevy 1500 4.3 v6 trans bands need to be adjusted I have two out of the four gears. Reverse tends to slip but works. How do I adjust the bands. And what side are they on. I baught it as is.

See what code the transmission has set, and get that info posted. It's just barely possible that you can fix it yourself, but not likely. If the transmission has grenaded, it will have set a few error codes which will not necessarily be correct in the computer's assessment of the problem. If you know how to change the fluid and filter, do that when you check the codes. If there is metal in the transmission pan, the transmission will have to be rebuilt.

check around oil plug oil filter and oil sending unit may one of them may get for u
