Hi all,

I bought a 2005 dodge dakota 2wd 6cyl automatic with a 42RLE transmission in it just before winter. It drove fine until the outside air temperature started to rise.

At first when i started the truck the engine would rev up and down and eventually stall only when its hot out. I found that when i started it i could hit the accelerator and the rpms would level out and everything would be ok. once the truck was warmed up i could turn it off and restart it with no problems. Doing some research i found that it might be the idle air control valve. I replaced it and the truck starts fine now.

At some point the truck started shifting hard into second and then eventually third. This only occurs when the out side air temp is high. (not sure what is the exact temp is. about 85F and up maybe). The outside temp can be 70F and the truck will shift without a problem. I have driven it for three hours in 70F and the truck does not have an issue. I was thinking maybe the transmission had to get warm first and then it would start shifting hard again. But this is not the case. One day it was above 85F and I drive it for three hours and it shifted hard into second and third the entire way. For the last two weeks i have been noticing this trend very distinctly.


I have done the basics like check the fluid and made sure there was no dents in the oil pan. My thoughts are maybe it is something to do with the electronics or the solenoid pack.


Any help and suggestions would be great thanks.

The check engine light is not on and no codes show up when plugged in. I followed the instructions on the transmission fluid dip stick to check the fluid. Not sure when the transmission was serviced last. Planning on getting this done. The truck just broke 100k miles

Seems like I read somewhere about a transmission temp sensor on these trannys , just a thought. Anyway, does the fluid look dirty or smell badly? How does the truck run? Sometimes engine issues affect how a trans shifts. Let us know how it shifts after the tranny service.
