Post subject:  2006 CRD SHIFTING PROBLEM WHEN COLD
Up to now the weather has been in the 40s and 50s in the morning and everything was just fine. This morning it was in the 20's and when I got out on the hiway the trans would not shift into overdrive at 64 mph like usually does. Once warmed up it shifted. Any ideas what could cause this? Once warmed up it shifts fine no matter what.

Thanks,

That is by design. The TCM won't do it until fluid is up to temp.

It also is programmed to do the same if the/when the transmission overheats :JEEPIN:

True... but be sure you have a clean air filter. That also will cause shifting issues.

How could the air filter affect transmission shifting?

Proir to puting in a K&N and provent my air filter would plug up within 5k and I would notice my shifting was bouncing all over. Mainly when cold and lower speeds. Now i clean the K&N every 5k when i change the oil. Never had a problem since.
