BIG PROBLEM -- Tranny --
« on: September 20, 2010, 04:18:42 am »
Ok... So about two weeks ago my truck wouldnt hardley take off. It was like it was taking off in 2-3gear. So i called suncoast and took it to the tranny shop. It was blowing the fuse in the motor compartment under "diesel Transmission". we replaced the fuse multiple times. So we sent the tranny back to suncoast and they made some repairs. Now the tranny was replaced... and doing the same thing! throwing 2 codes(I dont have them at hand but i know one was unknown and one was a low voltage) and blowing the fuse.

What should i do? could it be ecu? or how can i test for a pinched wire.

youve got a hot ground. . .check the wireing harness and make sure nothing is chaffing, you may have to pull the wires out individually to look at them.

I will check that as soon as i get home. We looked over it... and found nothing but ill check again. Suncoast is also sending me a harness so it will help to change it to double check. Any other ideas incase this dont help? Could it be in the ecu or the tranny?

If you can't find the short, a good auto electric mechanic can.  They have the diagnostic tools to figure it out.  I had a msifire on a 2000 Grand Cherokee once.  All signs pointed to a bad ECM after a new plug and cpoil didn't solve the problem.  Ended up being a chaffed wire.  Cost $25.00 to fix it right plus the $70 had invested in a coil and plug.  Glad I didn't spring for a $400 ECM  :suprise:  Point is- A good auto electric mechanic is worth their weight in gold!  Good luck  :cheers:
