700R4 no 2nd gear

i have a 91 700R4 and there is no 2nd gear it go strait from 1st to third at about 25 to 30 MPH and when i stop it drops back to first if i put it in manual low it freewheels i also have 4th gear so the band is ok.

i have had this transmission rebuilt 4 times and it always loses 2nd gear so something is being overlooked.

What would cause a 700R4 to not have 2nd gear but 1st 3rd and 4th still working?

i have checked the 2-4 servo and dropped the valvebody to check the 1-2 shift valve isnt sticking is there another valve i should be checking to see if its stuck?


PLEASE help im stuck and need a professionals advice i cannot afford to have someone rebuild it so im forced to fix it myself i have an atsg manual and it doesnt have a specific troubleshooting guide for no 2nd gear thanks i will check in every 15 minutes to see the replies as i really need help.

Re: 700R4 no 2nd gear

Ive rebuilt a few 700r4's. however i must say that I've never come across one that lost 2nd and be able to skip shift to 3rd. If you were to give it to me to fix, I'd first attach my 300psi Gauge to the MLP port on the side of the trans and check the pressure in Manual first. then of course all the other gears with the car stopped and then operate the 1 to 2nd to 3rd and 4th shifts and down shifts from 4-3, 3-2, 2-1. irregular Pressures in certain areas will lead you to a cause. however its hard telling if you can do this or not. a good Gm Trans book will come in handy.

Have you taken the Valve body apart? The Valve body separator plate is a good place to start sometimes. every time i tear into one i find the Balls have beat the plate causing a lip and sealing the ball(s) to the plate. and one that rebuilt the trans may have over looked it.... Ive seen it happen at backyard shops.....

Re: 700R4 no 2nd gear

Hi there,

The 700r4 in my 88 Iroc Lb9 misses second also. It goes 1-3 at medium throttle. At times, it seems like 2nd gear makes an appearance then promptly upshifts back up to 3rd. I've done some research and the only logical explanation is that the servo pin is too short, thus isn't applying the band in 2nd gear. Anyone have any thoughts on this theory? Would installing a corvette servo pin possibly solve this issue?
