Transmission Question


It sounds to me like the transmission is starting to fail. As the clutches inside the transmission wear the clutch pack gains additional clearance. Your pressures in the transmission will be higher with cold oil so it has a tendency to build a bit of extra pressure, but it's also slower in flowing through the transmission. This results in a harder hitting first gear. As the transmission warms up, it will reduce the viscosity of the oil and work fine. Cold weather kills automatic transmissions. Let it warm up before driving it or it won't last long. It will require an overhaul soon.

97 cavalier starts and runs ok from a cold start after a few minutes of warm up it starts to run rough and miss. If i try to drive it it will start out ok but won't shift automaticly but shifts fine m


Sounds like possibly more than on problem, crankshaft position sensor, or ignition module likely on starting prob which maybe affecting shifting due to hard code in ecm, or shift prob could be shift solenoid in valve body of transmission. Both parts readily available from local parts store

1998 malibu won't shift into gear when cold outside but, works fine in warm weather,why?


you need a transmission fluid and filter changed.because if filter stopped up.transmission fluid little thicker in cold climate make it hard circulate through filter.when engine and fluid get warmer fluid get thinner where it can circulate through filter cause transmission to shift correctly.

Trans shifts very hard after 5 minutes of stop and go traffic


A reason for hard shifting could be a problem with many things with various degrees of seriousness. It could be your ATF( automatic transmission fluid) is low or broken down and old. This would cause the hardness and the reason for stop and go traffic effecting it. Another possibility is your transmission is just shot, and the timing gears inside are worn and not properly shifting at the correct RPM causing a **** during shifting.

Some possibilties, not all!

2000 GMC 2500 4L80E hard shifting after warm up


1st and 2nd shift solenoids has sediment causing them to stick.or you got damage leaking seals. it might help if you put a little transmedic in transmission dont over fill. if your valve body full of sediment it causing valve in valve body to stick.this might help still might have to go in transmission.
