    Towing a car with a bad auto transmission
    11 yrs ago, the car was pulled forward to a wall, then would not go into R. NOW, it was started, put in N, and it tried to go forward without pushing on the gas. (I believe all the wheels were turning when it did this.) In R it doesn't do anything. I'm not sure if F ...

      the speed sensor is in the transfer case upper right close to the back of it. i dont think the speed sensor is giving you that problem though all it does is run the speedometer. how did the fluid look when you changed it?

    What are the cost estimates on rear pinion seal replacement
    Firestone said there is leaking around the differential in front of hub, and differential fluid is "milkshake" in consistency; they can't or won't do the repair.

      it's an hour job like 12 dollars for the seal and 40 or so for oil. it could possably be leaking because of a bad pinion bearing but i doudt it unless you leave it in 4wd all of the time.

      Thanks, I hope that is all that it will cost. took it to an independent shop yesterday and the owner implied putting in a new/used differential if they found metal shavings from excessive wear. I would think they would offer a gear kit instead

      first check the transmission fluid wipe the dipstick on a white rag or paper towel. it should be red i'm guessing this time it will be burnt, it sounds like it needs rebuilt. revers requires the highest pressure and is all most always the first to go. if the fluid isnt burnt check the kick down cable that goes from the throttle body to the transmission the little adjuster on the top can break and if not caught in time will smoke the transmission because it runs the trans at low pressure when it breaks and lets it slip.

      I had already did all that you've mentioned and I even changed the filter and fluid. I had it checked out and it was the "Governor" that was defected. I had it replaced and it shifts fine now. Thank you for your input and assist!!

    My 1994 Chevy will not engage into 4 wheel drive.
    The selector button only lights up in 2 wheel drive. When selecting 4 wheel drive nothing happens, no flashing light or 4 wheel drive indicator light. Would this be caused from a bad transfer case module, bad transfer case switch or the vacuum valve. Dose the vacuum ...

      I had a problem similar to this on my s10 blazer. It turned out to be that the electronic shift motor was bad. But before condemning it you should have it diagnosed. Check wiring, the switch itself, and the module. The shift motors going bad on this car is a common problem.

    Issue: hearing and feeling a "hum" that begins at around 25 mph, sound increases when steering right.
    Thought it was a bearing problem, but there is no grinding sound. The sound is directly related to speed, the pitch of the hum goes up. Left wheel was hotter than the left after test drive. Could it be an issue with the trans-axle bearings or u-joints?

      First step - have the stored fault codes or check engine light scanned - for free - at any local auto parts store; Advance Auto, Auto Zone, NAPA. Then, post a reply as 'add answer' with the specific code for more assistance. There may be a fault code stored in the OBD memory which may not be displayed as a check engine light.
      There are literally hundreds of possible fault codes - so for sake of simplicity and to assist the diagnosis and repair of the issue you are having, this step is fundamental.
