What happens if my transmission temp is too low?
The ideal temperature for it is 175 degrees, plus or minus 25 degrees, and when the transmission gets below zero degrees, it gets too thick. Shifting problems: When it’s cold, the transmission will shift harder and shift points can become delayed which can lead to yet harder shifting.
What temp is bad for transmission fluid?
#1 Cause of Failure The optimal temperature range for transmission fluid is 175 to 220 degrees. Above that, for every 20 degrees bad things happen, starting with formation of varnish at 240 degrees, followed by seals hardening, plates slipping, seals and clutches burn out, carbon is formed, and, ultimately, failure.
What are typical problems of an Allison Transmission?
Other problems include the transmission throwing fluid out of the fill tube, excessive engine flares, intermittent noises and the retarder not functioning properly. Abnormal shifts in an Allison transmission happen during shifting at high and low speeds.
What does limp mode mean on an Allison Transmission?
This transmission state is often called “limp mode” – a built-in protective behavior for some types of Allison transmissions when a serious problem is sensed. Transmission temperature was normal. I shut the engine off, and then restarted.
What’s the coolant temp on a Allison Transmission?
VMSpc showed that transmission fluid temperature was about 160 F. – somewhat higher than usual, but still within the “normal” range. The engine was revving higher, fuel mileage was down, and the engine was running a bit warmer (around 190 coolant temp). After exiting, I again shut off the engine and restarted, and the error went away.
What to do if you have a transmission problem?
Either way, you’ll probably want to clear the trouble codes . The best way to do so is to get a code scanner and scan the code to wipe it. It will go away after enough engine on/off cycles where the problem is no longer recognized.
