Speed sensor is probably dead or not hooked up or bad wiring.

SOURCE: speedo wont go past 55 truck runs fine

The transmission and speedo COULD be the VSS (Vehicle Speed Sensor) and or related wires. The Tach is a seperate circuit that gets signal from Distributor and power is fed through the "Gauges" fuse. The only way I see them being a related concern is either The ground (G200) and is located Behind the left side of the IP, below the fuse block, on the tie bar. the other way would be the IP cluster itself.
I think you MAY have 2 issues. I would get the VSS checked and make sure your getting a signal to the VSS buffer (located next to the PCM, around the glove box area). Make sure the buffer is sending the signal out. A Scan tool SHOULD be able to assist you in this. If there is NO VSS signal the transmission will not shift properly, if at all.
Also your speedo will drop off with no VSS.
As stated, this is just advise from experience and published material.
If in doubt, please take it to a Repair shop in your area your familiar with.

SOURCE: Needing to know why my Yukon's gauges stopped working.

You need to replace cluster, 99-02 Silverado GMC all will work even if it has a trans temp truck is pre wired for it. I put a 02 Denali cluster in my 01 silverado no problems. GM can reprogram hours and odometer if you want.

Im looking at a jeep 2002 with 4.7l motor. was there any problems with that year over all?grand cherokee sport.135000 a women with no knowlegde of buying a vehicle by myself. thank you jody

The 4.7l is an overhead cam V-8 motor. It is plagued with problems involving sludge build up, poor oil circulation, and engine failure due to lack of lubrication. Personally, I would avoid any vehicle with this engine.

The only thing that can make the noise is the transmission front pump, if the trans works ok try changing the fluid and filter, it may help or reduce the noise.

Help please

Try checking the crank sensor, (for sludge, and wiring connection) and having someone check the timing. It may have jumped a tooth. (so the engine isnt firing the sparkplugs at the right time) Also try drilling a 1/4" to 1/2" hole in the exhaust, forward of the catalytic converter, then try to start it. If it starts with the hole drilled, then that means that the catalytic converter is clogged, and needs to be replaced. If there is no difference, then the small hole can be plugged with a short bolt, or welded shut.
