Sorry but if your reverse is having trouble you will probably have to replace or rebuild tranny like me. Otherwise try new filter and fluid first.

Your valve body and possibly input shaft nut need to be replaced. The valve body's booster valve is worn down and won't create pressure. Before it went completely out it slammed on the input shaft nut and loosened it.

You need to replace the valve body and retorque the input shaft nut. The transmission is not junk. The above needs to be replaced and change the filter and fluid and do it every 20K miles.

SOURCE: 1992 GMC Suburban not shifting into OD, Transmission Modulator?

The shift down linkage on the carburetor below the gas pedal cable might need to be adjusted to increase the hydraulic pressure on the internal clutch plates in the transmission it shows you how to do that in a car manual.

My 1994 GMC Suburban wont shift out of first.....but will shift to second manually but wont go any higher........?


Sounds like a vehicle speed sensor, it governs shifting based on engine RPM vs Transmission RPM among other things. Located usually on the rear tailshaft or rear transfer case on the majority of 4L60E automatics.

Trannsmisson Problems


check carefully to make sure it is shifting from 1st to 2nd.... there is a "sun reactor shell" inside the transmission that when broken causes reverse, 2nd and fourth to be lost. it is an extremely common failure.

best way to check.... drive along with the gear shift lever in "2" you should feel one shift as you accelerate. then carefully bump it into "3" or "D" whichever the case may be. another shift should be felt. if you do not feel a shift, you have likely stripped the teeth of that shell. hope this helps..
