My transmission is slipping when accelerating from a stop. 2001 Pontiac Grand Prix, 3.1, filter and fluid changed one year ago.

Check your axle seals, cooler lines and fittings And the vent for the transmission.

Sounds like your transmission is slipping or your torque converter is bad.---check the transmission fluid level and see if it smells burnt and discolored.

CHECK FLUID LEVEL SOUNDS LIKE ITS LOW ON TRANSMISSION FLUID.

COULD BE MANY THINGS CAUSING ENGINE TO SURGE LIKE RESTRICTED FUEL FILTER.DIRTY FUEL INJECTORS FAULTY APP OR ACCELERATOR PEDAL POSITION SENSOR.

Have you checked the fluid level. It will do this when it's low. The fluid runs away from the filter pick-up.

needs wiper module. check bushings around wiper motor at the firewall.

you may change the filter and fluid, but in most cases it will not do any good. Find a good trans shop to check it out.

CHECK TRANSMISSION FLUID IT COULD BE LOW OR YOU NEED A FLUID AND FILTER CHANGE.YOUR TRANSMISSION IS SLIPPING REASON FOR SLUGGLISH TAKE OFF.

You can't use those two words in the same sentence when talking about transmissions. Best is new (rarely done) next is a rebuild (most times if from a good reliable shop, good but not cheap) then there is the used unit from a scrapyard..cheaper than either, but if it doesn't work, you get to pay r&r as many times as it takes, even if the yard guarantees it. (only way I'd do that is if I owned another identical car that I had driven and knew for sure the unit was good.

Have a Code P1811 on my 2002 Pontiac Grand Prix. The only thing I have noticed is it gets warm very fast. Haven't noticed any slippage with the tranny...What do I do??
