Have you checked the transmission fluid level?  Also, have you changed the transmission filter?  I would definately do these two before I would take it to a shop.  A typical transmission filter/gasket kit costs about $10-15 for that truck.  And the transmission fluid will run around $2-4 per quart.
Changing the filter is easy.  You will just take the transmission pan off and then pull the filter out, replace the filter, and then replace the pan gasket.  Then bolt it all back up and fill it with fluid!  It's that simple.

Sounds like a vacuum leak probably at the modulator valve on or close to the transmission.

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..

91 gmc shifts in and out of overdive


I had an 89 Suburban that started doing the same thing. Change the fluid/filter and add a quart of Lucas Transmission Fix. See how that does. Ultimately, you are going to have to rebuild or replace the transmission as the problem will only get worse in the end. Mine finally went down completely and cost me about $2700 to rebuild.

Transmission


Transmission model is 4L60E,and the symptoms you are describing is a common failure on these transmissions all the way back to it's predecesor,the 700 R 4 model.The reverse input shell,splines into the low/reverse planetary sun gear.The reverse input shell has a collar with splines made into it,and these splines are prone to stripping,and sometimes the collar itself will break free from the shell.Without the shell functioning,no reverse,and this is likely what you are hearing.Aftermarket companies sell heavy duty,and standard duty,replacements.Eventually,you will lose the forward gears also.Good luck.
