I recently had an oil change and transmission fluid change on my 2002 Pontiac Firebird(81,000 miles) and now i have a problem...when I push the gas pedal to accelerate it is very slow to do so and seems to not be able to get above 60, and the service engine light is on. Would appreciate any hints as to what is going on and what I can expect in repair bills. :(

Change the oil and filter (cheap ones), substitute one quart of oil with a quart of type F auto transmission fluid. Drive it about 30-45 minutes and see if the tapping stops. If not drive it some more. If it stops change the oil and filter again

the cable adjustment from the engine to the trans its the one with a square section that goes on the engine side push the metal section in and pull back on the cable then push the gas pedal to the floor that should set it

The manual says there is no dipstick. The transmission is a sealed unit, filled for life. It's really a bad design to not have a dipstick, because transmissions will weep a little fluid at times and it's a good idea to check the level once in a while. The Manual says that if it leaks fluid you have to repair or replace the transmission. Not a valid repair when the car has 160,000 miles and it's a pint low. There's a plug on the passenger side at the bottom of the transmission to check the level (with the engine running, so it needs to be on a lift) and there's a yellow filler plug hidden under the air cleaner on top of the transmission.

If you put in 5 quarts, it is either too much or too little. Both cases will cause the fluid to foam, causing jerky shifting. Mine was too low at 185,000 miles and it was banging shifts when hot.

By the way, that transmission needs about 9.8 quarts after a pan drop and filter change, so your 5 quarts is way too little.

timming is off. check the distributor cap . clean all connections with a electrical cleanner

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

sound like your your trany is on it's way out but you can try changing the il and filter may give you some time until you can get it looked at

It's called accelleration.

you should be able to use power steering fluid or automatic transmission fluid.

check the connections to sending unit mounted in tank if conn. ok replace sending unit
