transmission overdrive

2001ramtough · May 20, 2014

My 2001 dodge ram 1500 won't shift into overdrive. I put a new overdrive/lockout solenoid on it and new filter and fluid but no change. I didn't see any metal in the pan when I changed the fluid. Any ideas? I not getting any codes either. could it be the speed sensor? and if it was electrical would I get a code?
Thanks for your help

What overdrive

Transmissions don't usually "report" through OBDII. Some vehicles (BMW for example) have a separate data port for pulling not only OBDII codes, but also tranny codes, airbag, etc.
That said, this PDF ( http://www.edgeproducts.com/product_images/customer_support_article-pdf-39.pdf ) says P07xx would be tranny-related, assuming your problem falls into one of those codes.

Anyone know if we have a computer in these trannies, and how you can access the data if it's not a code reported through OBDII?

still need help

thank you for the codes. I'm still needing help troubleshooting. anyone else got any ideas of what could be the problem?

Just to be clear: What you're saying is, when you get up to a certain speed where you expect the auto tranny to shift from 3rd to 4th.... it doesn't. (Say, 45? 50?)

I don't have an answer for you, I just wanted to clarify the question. My truck is still new to me and I have my own issues to sort through.

yep thats correct. It won't shift into 4th gear or what they call overdrive.
