Question about 1999 GMC Sierra

1 Answer

I was towing and the hud said hot transmission fluid bring engine to idle. I pulled over and let the tranny cool but since then the trucks shift pattern has changed. First revs to 5000 rpm before changing gears and it seems to bounce back and forth from 2nd to third tacking back and forth at 2500 rpm

Your transmission oil is likely burnt,there by losing it's viscosity. check for brown rather than red fluid on dipstick.have transmission oil & filter changed.it is possible overheating will have caused additional damage.

Double check your trany fluid with the engine HOT and idling in park, top off if needed, otherwise if you disconnected the battery the transmission will have to teach itself to shift all over again which should only take a mile or two to accomplish on it's own, if not the tranny is history.

How do i know if my transmission is going out or if im low on fluid? cant seem to find my transmission fluid where would i find it? and what are the signs that my transmission is going bad?


If you know where the oil dipstick is, the transmission dipstick is very similar but closer to the firewall. Engine must be idleing to check tranny. There are normally marks on the stick that read "cold" and "hot". That describes the level of fluid dependant on tranny temp. Transmission fluid should be changed around every 30,000 miles. Symptoms of bad tranny, assuming good clean fluid, are hard shifting, won't shift (i.e.stays in 2nd gear) Or you accelerate and the tranny spins then jerks the car suddenly. An honest tranmission shop can tell.

I HAVE A 95 FORD AEROSTAR AND MY PROBLEM IS THAT THE TRANSMISION FLUID IS SOME HOW GOING INTO THE MOTOR IS THAT POSSIBLE AND IF SO WHAT MIGHT BE THE PROBLEM THANK YOU FOR HELPING


It sounds like you have a leak inside your radiator, if you have an automatic transmission the fluid needs to be cooled on long trips, hard loads (towing etc) or on hot days, this is accompished the same way your engine is cooled, by running lines from the transmission then through the radiator, the air going through the rad and also the coolant from the engine cools the tranny fluid then routes the cooled fluid back to the transmission. If the lines that run through the rad have a hole in them the fluid will leak out and into the engine coolant (antifreeze) and the fluid will make it's way into the engine through the engines cooling system, the other side of this is that engine coolant is possibly making it's way to your transmission and this is an even bigger problem as the coolant does not have the lubricity properties needed by your transmission and you are soon going to have operation problems with your transmission. You need to get this fixed soon and have both the engine cooling system and the transmission flushed to remove the cross contamination.

Need to add tranny fluid to '99 Rodeo, but where??


CAUTION: DO NOT OVERFILL.
Overfilling will cause foaming, loss of fluid, abnormal shifting and possible damage to the transmission.
1. Park the vehicle on level ground and apply the parking brake firmly.
2. Check fluid level with engine running at idle.
NOTE: Be sure that transmission fluid temperature is below 30degrees C (86degreesF).
3. Move the selector lever through all gear ranges.
4. Move the selector lever to “Park”.
5. Let engine idle for 3 minutes and open the overfill screw (1).
6. Add released transmission fluid until it flows out over the overfill screw opening.
7. Let engine idle until a fluid temperature between 32C (90F) and 57C (135F) is reached, then close the overfill screw (1).
Torque: 38 Nm (3.9 kg·m/28 lb ft)
NOTE: To prevent fluid leaks, the overfill screw and oil drain screws gasket must be replaced each time these screws are removed.

CAUTION: Do not open overfill screw with engine stopped.
CAUTION: DO NOT CHECK FLUID LEVEL UNDER THESE CONDITIONS:
 Immediately after driving at sustained highway speeds.
 In heavy city traffic during hot weather.
 If vehicle is towing a trailer.
If the vehicle has been operated under these conditions, shut the engine off and allow the vehicle to “cool” for thirty (30) minutes. After the cool down period, restart the vehicle and continue from step 2 above.

This is how you do it.

Ensure that the transaxle case temperature is 70° to 90° F (21° to 32° C). With the engine running, shift transmission through all gears. With engine idling in PARK, remove the check plug from the transmission. If transmission has been overfilled, allow fluid to drain out. If no fluid drains out, add fluid through the TRANS FLUID fill cap under the hood on the driver side in 1 pint (0.5 liter) increments until it slightly flows from the check plug. Reinstall the check plug.

Tranny high shifting


There is a linkage on the Loadflight A-500 transmission that travels from the throttle linkage to a lever on the transmission. Proper adjustment of this linkage controls the shift schedule of the transmission with respect to engine throttle position. This would be the most likely place to start after ensuring that your fluid level is correct.
