Question about 1997 GMC Jimmy

4x4 won't move!

Ok I just bought this thing at an auction! Runs great but when I put it in forward (2x4) it's kinda sluggish but then runs out fine. Now in reverse it's great. So the 4x4 issue when I put it in 4x4 hi it wants to move a little then stops. The motor is running good but it just doesn't want to move (slower than a snail then stops). So any suggestions thanks!

I would begin by cranking and letting the engine warm up, checking all fluids relating to drive train. Once you've established good fluid levels and if the transmission is automatic, I would recommend checking the transmission kick down cable. It sounds as though it would work if fully going into gear. If it is standard transmission or if you check the kick down cable and everything checks out fine, I would run vaccumme test on EGR system. These tests are based on the engine being in sound running condition, i.e. plugs, wires, cap, rotor, and fuel filter. Hope this helps, good luck!

How do I fix my rv it wont go forward when floored. feels like brakes are on. reverse is ok


If you are getting no power, but the engine is doing it's thing, you may have no forward gears, or it may be in a higher gear. If it has been reassembled with vacuum lines and components disconnected, they may have messed with the shifting of the transmission. I would start by verifying it is in 1st when starting out.

4x4 indicator light


I have seen this issue in some 4x4 vehicles. The issue may be that although you have moved the shift lever, because there is pressure on the axle components, the vehicle has not released the front wheels. After shifting from 4x4 to 2x4, allow the vehicle to move without torque for a few seconds, allowing the components to move into 2x4.

I bought a 92 Chev 2500 4X4 from a guy just recently. He said the tranny wont go into gear. I found the transfer case was in neutral. So i put it in gear and away it goes. But reverse seamed sluggish. ...


If your transmission is a 700r4 (4l60) you have a reverse band that engages when you want to go in reverse. since it drives forward your low reverse clutch and your fwd clutch are working. This leaves the band which was probably slipping now is not engaging.

4d56 Pajero Turbo Diesel, blow's alot of smoke under load. Replaced airfilter and using injector additive atm. Still blows a heap of smoke.


If your car is fitted with Manifold Air Pressure sensor (MAP) check that is operating OK. Sometimes if this is as at fault it can send the wrong signal that the engine is running lean and the engine computer (ECU) in turn compensates by injecting extra fuel. The clouds of smoke are unburnt fuel so not only does it look bad but it is wasteful/costly. The fault on a MAP can evolve slowly and therefore evades the computer diagnostics check for some while before being picked up. Also on the list of things to look at are:- 1) the mass air sensor on the air filter ducting 2) the EGR exhaust gas recirculation valve (perhaps needs a thorough clean) 3) the differential pressure feedback exhaust (DFPE) sensor - lies upstream of the EGR but if faulty can combine to lead to errors in fuel injection quantities.
