Sounds like the fuel supply is inadequate. Check for a plugged fuel filter, or possibly the fuel pump is losing pressure. I had a 93 Chevy V6 that acted the same way, and after checking everything else I replaced the fuel pump, which solved the problem.

More than likely problem is with rear speed sensor. It is located on top of rear differential. New from dealer is about $35.00. A lot of the time you can remove the old one and give it a good cleaning. Easy to repair but just be careful that you dont break it off.

My 98 ford expedition has a rumble when I go over 45 mph sounds like grinding and the whole truck shakes I was told it might be a trans problem any suggestions


Have the people that tell you things actually ride with you

You probably know more than they do

If you have no vehicle experience at all, then you will have
to pick up someone at a shop & take them for a ride

You could have transfer case problems
Drive Shaft
Wheel Hub Bearings

If the trans was that bad you would know it

It may be a problem & not work correctly, but to shake
the truck, I doubt you would be here or using it

Intermittent rumbling sound in transmission at ~30 mph when going uphill and easing up a little on the gas. very much like driving over a rumble strip on the highway like they put in front of toll booths....


Do you have the problem when you turn on the car as well? I had this same problem, turns out the alternator was going bad. A few months later the alternator went. After the alternator was replaced, the problem went away.

Hello! The likely culprit is the Throttle Positioning Sensor (TPS)...A Black button device with a 5 pin connector which is held in place by 2 bolts...It is located on the throttle body...Wire colors are; Red, Black, Brown and Blue...Cost is around $130...

If you have a voltmeter it can be tested...Straighten out 2 paper clips and push them into the rear of the connector on the Red and Black wires...Set the meter to read 5 volts...Hook the + lead to Red and - to Black...With engine at idle meter should read less than 1 volt (approx .85V)...Slowly increase throttle...voltage should rise SMOOTHLY to 4 volts...If voltage skips, jumps, or acts erratic the TPS is defective...

97 Ram 1500 over revving until hitting 45 mpm


It sounds more like a cable or linkage sticking, and yes it is transmission related, sort of, just because of the high RPM before shifting. Spray all your cables good with lube, at throttle linkage, and get under and look where cable & linkages are at side of transmission, and spray them good too, and work them back & forth, to try & loosen them up. Truck shut off & in park when under it eh.!
Then work shifter back & forth, gas pedal to floor & up etc, to try & loosen things up. That may just cure your problem.
