Transmission Malfunction

[Infinitiguy19]

I have a 1991 q45 and sometimes when its really cold like 20-30 degrees Fahrenheit I get a "Transmission Malfunction" error message and I did the check but I stays at the "A/T Check screen" I can't seem to get a code which i think is good or I might be doing the test wrong.

Is that normal or is there something wrong with the transmission the car has 166000 miles.

You should kiss the ground and the car that Q45 is on.My '91 Q had two new trannies by 76k.Boy did you luck out!!!!

Somehow I don't think this 166k was the as built transmission..........as far as I know almost every 91 failed prior to warranty.

Age is more important than miles. Few lasted 7 years, pretty much the same with Nissan rebuilds 7 years is a good life.

Why you budget and save $400 per year as prorated life of transmission.Some have lasted 10 years depends on shifts per mile.

But then again 10,000 miles per year [average] is so low hard for me to relate to the typical ATL situation same with Cold weather [which might have been somewhat protective] until now?

Best to find a Consult and read the codes.
