4L60E Transmission Rebuilt ' eBay

It could be a couple of things but all related to the transmission . The valve body could have contaminates and not allowing the fluid to go where it needs to the solenoid pack could be the problem . Take it to transmission shop and have them put it on a transmission scanner they would be able to tell you more info about the problem . Hope this helps

might its require clean injector or check the coil

and please check these point:
air filter
fuel filter
plugs cable

look under the seat there is a large plug that feeds power to the seat

in 1991 chevy used 3 differant trasmission's a 4L60-E, 4L80-E and a 700R4 in 1993 they used 2 differant transmissions a 4L60-E and a 4L80-E if your truck has the 700R4 then the 93 transmissions will not work if you ned to find out what you have in your truck and what is in the other truck. if they are the same they will swap the only diffance in the ext. cab and reg cab is the drive shaft. but the transmission have to be the same modles a 4L60-E will not replace a 4L80-E and nothing will replace the 700R4.

When was the last time you had an alignment done? Since it happens at those speeds primarily, it sounds like an alignment problem.

I have a 2003 Chevy Avalanche 1500 Z71 4X4. What you describe happened to me (6) times last week. #1, I replaced the ignition switch, $32.00. The issue happened again last night and recorded the code P1514 (Throttle Body performance condition). #2, I cleaned the MAF (mass airflow sensor) and the throttle body. These parts require specific cleaners, which can be purchased at any parts store. Truck runs like new. Best regards, Mike Pyne
