Question about 1993 GMC Sierra

1 Answer

I have a 1993 GMC Sierra 4x4, with a 350 motor, a 4L60E transmission with a 3/4 ton upgrade and shift kit as well. Now when i press on the accelerator it falls on its face and then picks back up. throwing a low throttle position code as well as exhaust gas recirculation error. It does not have the egr valve hooked up(never did) it did have an exhaust leak but i fixed that. I have adjusted the accelerator cable (I dont think i should have done that) another problem is when i shift from park to reverse or drive it snaps into gear. some one help me please

I would check the engine timing and do a check on the exhaust to be sure it is not partially blocked. As to the snapping when you shift I would check the universal joint to be sure it is ok and the rear end may have some play in it.

SOURCE: no reverse after rebuild on 4L60E Transmission from 1995 GMC Sono

There isn't a modulator on this trans as it is electronic

You can have first gear going forwrd but no reverse. It is possible. The low/ reverse clutch isn't needed to go forward.

Tword the bottom of the steering colume. It will have a couple of connectors going to it and a couple of rods going to it from the igniton cylinder. IT is on top and not easy to get the bolts out of it. You will need to remove the close out pannel to even be able to see it.

SOURCE: 95 GMC Sierra 4x4 350 5.7 rough idle problem

It sounds like a MAP sensor going bad. MAP is short for manifold absolute pressure sensor, it senses the manifold pressure and applies the right amount of gas with the right amount of ignition timing so the car runs and performs well if this does not work properly. It throws off the whole loop cycle for the computer, which in turn makes it run badly and get poor fuel economy. It can causes the engine to have a lack of power, combined with a loss of fuel economy. Poor take offs and sometimes an occasional stalling may occur if the MAP sensor is faulty and sending the wrong signals to the ECM.
Hope this helps and thank you for using Fixya.

93 gmc sierra 1500 4x4 extended cab , shifts hard into drive and when shifting from 1st to 2nd. just put in a new 4L60E transmission.


You have the electronic version of the 4L60, so if it was doing it before with your old tranny. I'm going to point the finger at the computer. Probably nothing wrong with your old unit.
If you didn't replace this, then maybe you should.

Electric transmission


Hi. I have a '93 Chevy Suburban that is on the 3rd transmission. What you probably have is the earlier 700R4 transmission. What you should have is the 4L60E. I have done ALOT of research on these transmissions, and what I've found out is this: the 4L60E is essentially the same as the 700R4, with the exception that the 4L60E is completely controlled by the vehicle's computer. The 700R4 uses a more antiquated valve body with a TV (throttle valve) cable. In theory, you could use the 700R4 if you connect the TV cable and properly adjust it. If it's a 4X4, your speed sensor is in the transfer case, so that wouldn't be an issue. The 4L60E used in '93 and '94 will only work in those model year vehicles, because of the type of shift solenoids used. The newer units used pulse width modulation solenoids, as opposed to the older on/off solenoids. I have run my truck with the transmission unplugged and the engine still runs fine. The major problem with using the earlier 700R4as opposed to the correct 4L60E, would be emissions compliance. If you want to discuss this further, email me at big.bad.bones@hotmail.com
