When my engine is cold, the transmission won't shift from 2nd to 3rd until I reach around 38-40 mpg. If I let the engine warm up about 5 minutes, it will shift normally. Oh, if I take off cold, and reach the high enough speed (38) at around 2600-2800

How many miles on your Camry? When was the last time that you had your transmission serviced? How is the condition of the fluid? Is it really Dirty? Always make sure that your maintenance is up to date. Dirty fluid or filter can cause shifting problems. Is there a power and economy selection for your transmission and if so, what mode is it in? If it is in the power mode, the upshift will be delayed a very long time when it is cold. If this doesn't apply, then it may be that a coolant temp sensor is staying cold for too long and this too will delay the upshift, especially the 2-3. How does your temp gauge read? Does it take a long time to get into the middle when that car is started cold. This could mean that the T-stat is staying open and this will keep the engine cold too long which will delay the upshifts. Hope these hints are a help. I have had to repair some Toyota cold shifting problems recently and these were all in play on a few Toyotas.
