Question about 1992 Cadillac Seville

1 Answer

When you floor it from a dead stop; 1st gear will not change when it hits the red line. it bounces off of it, and you have to let off to get it to change to second. or, it will start over-reving.

    There is only two cables that run to the throttle body. One is the accelerator pedal cable, and the other is the cruise control cable. Is there anything else that could cause this problem.

    I figured out what the problem was. The modulator on the tranny and the seal around it were worn out.

    I will try this and let you know if this works.

    sorry about the first post, but i was testing the link to make sure it was working, fixya has been having some problems with the sight, we have not been able to post an answer to you question do to the technical problems on the sight, i tried to answer your question several times yesterday but was unable to do to the technical problems.

    so with all that said lets get to you 1992 cadillac.

    what you are describing is a stuck governor in the transmission, but i do have a question can you manually shift the gears? what i mean is if you put the shifter in low range and take off then move the shifter threw the gears manually will the transmission shift? if it dies then it is probably just a stuck governor, and you might be able to just service the transmission and fix the problem, you service this transmission by removing the transmission oil pan and replacing the internal oil filter then refiling the transmission with new ATF and a qt if transX ( it is like miracle juice in a can ) it take the transX around 100 miles to start working it magic, if after a 100 miles or so the problem has not gone away, of if you can not shift threw the gears manually then you most likely will have to replace the transmission, but don't give up hope yet give the transX a chance it is a great product, we use it almost daily in our shop.

    if there is any thing else i can do for please let me know.

2007 mustang gt have engine knock problem when going from 1st to 2nd gear at 5000 rpms?

5.000rpm's high revs and you run into problems with valve bounce ( hitting pistons) ,ring slap, gudgeon pin knock, big end noise and possible main bearing noise . You may also be getting a hydraulic lock in the hydraulic followers that is holding the valves open too long. Unless the engine has been specifically built for these rpm's any loose ,worn on unsuitable part will cause problems I am thinking that you have around 100.000 miles on the clock after 7 years and the motor is not young Ford V8 engines specifically built for a 500 klm race are limited to 5.500 rpms because they destroy the timing chain if driven over that speed .

I have a 2008 GMC Yukon XL Denali. I hit a small snow drift yesterday and now my speedometer stopped working, my RPMS are bouncing, oil pressure is bouncing, temp is bouncing and vehicle wont shift out of...

Vehicle speed sensor, wheel speed sensor, your VSS operates you MPH and tells the trans how fast you are going and when to shift, it is telling the trans that your not moving so why would it shift? Next your ABS wheel speed sensor tell the car what wheel is moving at what speed to activate traction control and abs systems both are very sensitive and easy to break

When was the last time the transmission fluid and filter changed? I would have that serviced first. If it is an electronic transmission, the line pressure might also have to be reset.

Ford : back the truck up 10ft put truck in neutral and disengage four wheel low. (You can't drive in four wheel low cause its a pulling gear and you won't do over 3-5 mph.)
