1996 Z71 5.7 ltr transmission shift

1. Oil coming from the ext. vent means Overfill fluid transmission or valve body problem (need to open the transmission to overhaul it) but usually overfill. 2. Do you have any transmission faulty code 3. If you pull a trailer, heavy load there is a function in PCM (powertrain control Module) that raise the pressure to compensate the slip at clutch pressure and if you unhook the trailer and go on the highway before the PCM learn it, it will shift hard. What GM call the "shift adapt". You probably have a 4L80E for transmission or the 4L60E depends on the truck's options. hope it helps.

1996 GMC SIERRA XC 4x4 wont even turn over

What is the voltage on the battery ? If it's not in the 13.5 volt range the battery is not charged. What does the battery read when you try to crank ? It should be in the 10.5volt range. Get a set of jumper cables. Hook them up correctly and see if it cranks. If it does - the battery is not fully charged or it's a bad battery. A car battery can produce enough amps to light lights and other small stuff but not produce enough amps for the starter to turn over the engine.

HOW TO FIND OUT IF A/C PRESSURE SWITCH IS BAD

Probably the high pressure switch on the accumulator - try disconnecting the connector and jumping the pins to see if the clutch will engage. If that is the problem, DO NOT leave it jumped - replace the switch. If that is not the problem, you will have to check the clutch wiring, relay and fuse for continuity back to the HVAC controls. If that is OK, the problem will probably be in your HVAC control module.

1998 Chevy silverado K1500 5.7 liter

I would check a few things: Load test the battery. If its got any age on it at all, this could be the culprit. Test the starter. Check for loose connections at the distributor cap. Make sure the rotor in the cap is seated and that the cap is properly seated. Check for loose connections on the battery, the starter and make sure you have fuel pressure on the injector rails (key on, detent the shrader valve .. you should get fuel).

Took my 1996 gmc sierra 5,7 to get a oil change,,

They make oil pan plugs for this situation. It's a bolt with a rubber spacer that expands to seal the hole when you tighten it. If the old plug is still in the pan, use vice grips to thread it out. No need to replace pan, but maybe replace the oil change shop. Guys you went to have no experience.

My 1996 GMC half ton 2wd revs up to about 2000 rpm on start up without touching the accelerator. After a few seconds, it goes back to normal. Also, when you put it into drive or reverse, it accelerate

If the throttle cable is not attached properly to the throttle body or you have a bad motor mount, the throttle cable may be pulling the throttle open as you shift into gear. Open the hood, find the throttle cable on the throttle body. Inspect how it is connected and also how the cable is fastened in the engine comoartnent. Next, watch what happens as someone else starts the truck and puts it into gear. If the engine shifts significantly, check for broken motor mounts. If the throttle cable is misbehaving, correct the installation.

I have a 1996 gmc

Possibly a busted fuel pressure regulator diaphragm. The regulator is mounted to the end of the fuel rail. With the engine idling, pull the vacuum line off the regulator port. If gas comes out of the port, replace the regulator. 0996b43f80219b2e-sulc2cgngkoxge0rocse0fez-1-0.gif

Something wrong in the fuse box if you only have .4 volts at the fuse. Maybe a loose terminal in there.

I have a 1996 GMC Sierra 4X4 truck, have had a

Hey Dennis. Opppsss.. was this transmission serviced regularly?..no, ok.. this is a common problem, you will need to take it to s QUALIFIED PROFESSIONAL to get the trans rebuilt.. If you live near a local drag strip, go there, ask the drag race mechanics who the best transmission man there is?? There is always one or two the drag racers relay on.. I would trust him to get it done right (BEFORE I would trust a "chain" transmission store!!!!!) I, personally, have had two transmissions do this.. one a 96 suburban and a 95 Silverado.(both inherited and never serviced).. I found the guy that did mine this same way.. GLAD I DID.. it was less $$$$ and great work!! If no drag strip.. ask the custom car guys...
