Transmission shifts out of 4th


OldsCrazy

Recommended Posts

It seems on a hot day my 95 Cutlass Convert will shift into 4th ok then once I sit in traffic and then get going again the trans will shift into 4th but then I am stuck in 3rd until I shut the car off and back on. That may work for a mile or 2 then it will pop out again.

 

Once it sets it is ok again but if it heats up a little it will pop out of 4th agian. It never happens in the spring, fall or winter so it must be a heat thing.

 

Any ideas besides a transmission rebuild?

 

Thanks,

Hey Old Crazy

 

Do a pan drop and do visual inspection, install a quality trans filter and some DEX VI, I would guess 7 quarts.

If you still have problems. replace the radiator or add a trans cooler.

 

Good luck.

P.S DONT EVER ADD LUCAS to your transmission, the problem you are having is typical :biggrin:

I will give that a try, thank you for the help.

It's no problem I also had a similar problem with my transmission in my 1994 Oldsmobile Cutlass Supreme 4t60e

Just dont settle for a flush/fluid exchange at a quick lube, you must remove the pan.

 

Good luck:)
