HELP! Transmission problems. Starting in 3rd, and TC issue
Truck - 03 dually, standard output. only mod is a TC lockup switch.

Ok so the tranny worked fine but it was due for a flush and filter. So i got a new filter and atf-4 and did the flush. For 3 days after the flush the trans worked perfect.

Last night the truck would not shift out of 1st gear. The revs would hang at 2500rpm or higher for several seconds, sometimes almost 10 seconds! Then shift and the rest were all good.

This morning I leave for work and its taking off in 3rd gear. I am sure its third because I can drop it into (2) on the shifter and it will take off easier.

Also now my converter locks in overdrive about 5mph later then normal. My TC switch still locks it when needed tho.

I have to take a 500 mile drive tomorrow so this has to be fixed today. What do I need DTR?

 

sounds like gov pressure sensor going out. its going into limp mode. check fuse and relay first.

 

what relay and fuse?

 

trans relay...cant remember if there is a fuse too....

 

checked them both. Tested GOOD.

Governor then?

What else should I replace along with it?

 

DEALER WANTS 125 BUCKS! Geez

 

hi
before you doo aany repairs read the codes wright them down and erase them and test deive it .
sometimes just erasing the codes clears it !

 

Wound up taking the rabbit instead.

Ordered the PATC REgovenor kit. I went all out!
