Transmission problem
1999 Acura TL Two Wheel Drive Automatic 140000 miles

This is a repeated issue. The trans oil is black. The transmission makes a noise when pushed to reverse, doesn't make any noise for others drive or neutral.

Heats up the engine fast and the local repair shop didn't want to change trans oil and asked me to check with a transmission shop. The trans shop said run the car with the noise and don't change the oil as the car might react badly.

what is the problem? Why is the trans heating the engine and turning the oil black. The oil was changed a year back when it was found black.

Any clues?

Hi ramgct,

The only way the tran can heat up the engine is when it is running at high rpms most of the time. Possible cause is the trans is stuck in low gears and not upshifting.

This would cause the transmission fluids to turn black.

If the engine is overheating, was anything done or test carried out?

I checked the Engine with the dealer last year. He mentioned the oxygen sensor needs to be replaced by checking the codes and the transmission is dying. He explained dying means it may stop working anytime.

Checked with another shop a friend's friend, he replaced the transmission oil and a pump between tranmission and engine. He said the oil replacement should resolve the issue, nothing with the transmission.

Checked with a transmission shop if the transmission has problem and needs replacement, he said the same thing as you, the 1999 honda models/same as acura have 2nd gear issue. He took a test drive, didn't open anything. He told me not to change oil even if it is black and stop-by if there is anything else later.

Any suggestions?
