My car had an accident and was repaired. The Automatic Transmission fluid was changed and since then the car ceases to accelerate after about 15 to 20 minutes drive. I've been told that a wrong fluid was used, I have purchased the right Toyota transmission fluid now. 1. Do I have to open the gear box, clean the filter before refilling with the right fluid? 2. Will refilling with the right fluid stop the problem? Thanks

Check your automatic transmission fluid. If low, change fluid. Transmission is slipping

Check transmission linkage.

Check the transmission fluid.make sure the car is at operating temperature and in park.go to parts store and buy transmission filter kit. automatic transmission works on fluid pressure if it is restricted the tramsmission won't shift right.the fluid and filter are to b changed usually between 40 to 50k miles

Hello, what kind of noise? Clanking, whining, knocking, cladder, squawking,squeaking, rattling, etc...
It could be a number of things. But first, have you ever had the automatic transmission fluid changed? If you have a lot of miles on your vehicle and never had the transmission fluid changed out, ti might be to late. The biggest killer of automatic transmissions is heat. The heat generated by the transmission gradual destroy the viscosity of the auto transmission fluided. GB...stewbison

check the tranny fluid, make shure the fluid is pink and not brown, when was the last time the fluid and filter where changed?

the worst thing it could be is a transmission failure, but I would try checking the transmission fluid before I would get to worried.
to check the transmission fluid, drive the vehicle for 15 - 20 minutes, park on a level spot, set the emergency / handbrake and place the vehicle into neutral, pop the hood and locate the transmission dipstick, check fluid level, add if necessary.

if the fluid has a burned smell to it or it is almost black it is probably time to change the fluid and filter on the transmission. fairly easy to do especially if you can locate and buy a haynes or childers car repair manual. most autoparts stores carry them for 15-25 dollars (atleast around here they do.)

He is wrong it's the speed sensor on side of trans

when it reaches its top speed of about 15 to 20 mph does it rev out or does it stay in that gear?

Ya but if nissan planted filter's in there tansmission's then they would grow,right?NISSAN does not install filter's in the tran's.It is a permanent screen and luckily for people all I have to do is undo the plug from the pan and drain while hot, screw the screw the plug back in and funnel your new fluid back in to the tran from the dip stick tube(my 04 sentra 1.8s 4speed automatic takes 5 quart's but holds 6-type D nissan fluid from dealer,change about every 15 to 20 thousand miles to keep it clean and thin.Remember trans fluid is petroleum and get's hot burn's and thicken's making restriction's on rotating metal).My car has over 90,000miles and shift's perfect
