Thanks for the part so quickly Abran! My mechanic was able to get the speed sensor off that one and installed on my lr3. Still getting shifting issues around 4th and 5th gear. Error codes are 730 and 735.

I'm about ready to just dump this truck for cheap unfortunately. Its a great looking and driving vehicle but no one can figure this out. Mechanic doesn't believe it needs a new tranny. He also tried replacing the brake lights.

 

Damn, Sorry...

 

Ya, its crazy. I just picked it up from the mechanic since they were out of ideas on how to repair it. Drove it for about 40minutes and it only acted up 2x's. Both from 3rd to 4th gear shifts. Will someone knew what to do on it. Guess the only option is a rebuild if I want to keep it. I may just trade it for something else at this point.

 

Start simple. Are both the front tires the same brand, size and tread depth? I've seen 5/32" in tread depth difference side to side cause a no upshift from 3rd to 4th without going to sport mode. Sensors look at each wheel speed while driving. if the computer sees too much variance, it will not upshift past 3rd gear in standard mode. Will it upshift to 4th in sport mode?
