Default 91 auto, no 2nd gear

We have a little problem with a 91´auto.
The car always skips 2nd gear, and you can not force it to run in 2nd.
Also it will not engage the 4th gear either, It just revs up, but dosent catch the gear.
The gearbox has been overfilled by the previus owner.


Any body has any ideas on this?

sounds like you have an internal leak, and your transmission can't squeeze the clutch packs adequately

Not that I have any definite knowledge here, but there might be an apply piston seal gone bad from age

The common link for 2nd and
4th is the band. If you have also lost reverse, the reaction shell broke. 4th and 2nd only point toward the band, or band anchor pin.

I had my sun shell gear take a dump on me in my 92.....no 2nd, 4th or R like Pete said. Man that was no fun.

Sun shell is the most likely cause.
