TS chip fried my PCM
 

How can I prevent this from happening again, and why did this happen to begin with....

Prior to installing - put the key in your pocket and disconnect the batteries.

I had a diesel perfromance shop install it that does 10 of these a day. So what does that mean? I disconnect my battierys everytime that it happens(every 30mins) and it goes away, if the chip is turned up from stock it happens in like 5 mins. my truck only has 135,000 miles on it

are the conections clean?

I have no idea TSD did everything, could that cause my truck to go into limp mode??

So is the PCM dead or does the truck stall?

What happens in "like" 5 minutes? Your going to have to explain what "IT" is.

There is no "limp" mode on a 7.3...

Ok well the trans shop that has done e4od trannies for 10 years said it a limp mode that protects the trans, and "it" is the flashing overdrive light....... They said it could be PCM, and I herd that a ts chip can cause it

So to be clear...

The TS chip did nothing to your truck, or the PCM.

The TS chip added enough HP to kill your tranny. End of story.

Flashing OD light means code stored in the PCM, pull it and go from there. Could be as simple as a VSS in the rear end, or a valve body issue...

:edit:

I'm sorry if I said something to hurt your feelings, that was not my intentions. However you posted that a TS chip fried your PCM... That was just simply not the case.

I am trying to get exactly what your problem (truck related) is, and what you were giving myself, and others was not enough to get any good information back to you.

THanks!
