At -3*F, my son started and drove my M1008 to school yesterday morning. After sitting in the parking lot all day, he started it up about 9:30 last night at -9*F with no problem. Let it warm up 5-6 minutes and headed the 5 1/2 miles home. Drove easy the first mile, but when he tried to get up to the normal 50-55 mph, the engine would race, but he could not pick up speed. When he let off the gas pedal everything was fine, It sounded fine and the engine revved as it should when in neutral or park. He eventually made it home driving slowly in 2nd gear. From his description, I am assuming that the transmission started slipping when it shifted into 3rd gear.
Transmission fluid level was full, color and smell are good. Fluid and filter were changed less than 7500 miles ago.
After sitting in the 35*F heated garage overnight, I drove it about 25 miles today at -15*F with no problems. Dumped a can of Sea Foam Trans Tune in, and drove another 5-6 miles with no problems. It is sitting outside tonight at a current -4*F, and it is supposed to get down to -10*F, so I will get a good test on it in the morning
My guess is that cold caused a valve to stick, and/or seals hardening and shrinking, allowing oil to bypass in a 28 year old transmission.
Anybody else have any ideas or advise?
