Hi y'all,
I spent about 45 mins searching on "transmission", and aside from gaining the knowledge that my tranny isn't the only one that's ever puked, I didn't see anything related to Superchips programmers being a possible cause of transmission failure.
The long story:
I've got 67k miles on my 2nd hand '02 and about a month ago, my tranny puked going up a very steep grade, pulling a 9k lb 5th wheel and a cab-full of family and dog on a 98F day. I noticed the trans temp gauge ramping, so pulled over into a turnout and saw a fast flow of ATF boiling out of the tranny and a trail back down the road as far as I could see. Since it was a dangerous place to stop (with no cell service), I had little choice but to try to limp it up over the top of the grade to a safer turnout after letting it cool for about 20 mins. When I reached the turnout, the truck pitched a fit and would not go fwd or reverse...it was cooked. I guess I should be appreciative that it went the extra couple of miles to get the family out of harm's way. I'll skip all the frustration related to towing a crewcab and 30' 5th wheel down into town, but three days later, I had a new rebuild and cooler installed and I was on my way home...wallet $3800 thinner.
The question that's been nagging me is whether the Superchips tow performance setting could have hastened the failure of the transmission. I thought I had it in tow safe, but no.
Any thoughts?
I'm going to take it up to a local tranny expert next week and have him give it a once over and make some recommendations to try to increase reliability and squeeze a bit more than 67k miles out of this one.
Thanks in advance.
