Transmission Trouble
« on: August 18, 2015, 08:15:43 AM »
I have a 95 3500hd bucket truck with 4l80e  transmision. The transmission went out so I took it in for rebuild and put it back in, 500 miles later it burnt up. The transmission guy said it is because some of the plastic on my transmission range switch was wallerd out causing a little slack. He said this caused the transmission to burn up. From all the wiring diagrams I have seen none of the wiring from this switch goes through the computer so it doesnt seem like that would have anything to do with it. Has anyone worked with the range switch much? Does this sound right to you?

If this happened within 500 miles of rebuild then the wear on the switch was already there. If he truly believes this caused the issue (which in my mind is 100% BS) then he should have replaced it while reinstalling the transmission, to prevent any problems.

I pulled it out and took it to the shop for the rebuild then reinstalled it, he blamed me for not getting the switch right so he rebuilt it agian for half price and put a new switch on it. I have the transmission bolted in place but it isnt finished being installed. I wanted to get some opinions before I finish. I have not worked with auto transmissions before. I dont want to fry it agian.

I had a shop rebuild one for me and a week later i lost reverse and drive and took it back ended up being a relief valve that they didn't replace the first time the black switch i believe is the range selector and neutral safety switch and reverse lights I am with Richard it sounds like he might be full of it.

I know it's not your exact same situation, but this is why when I see people asking about where to order a transmission from (like the mail order places) I always recommend having a trusted local shop do it, because if they do the install, they can't blame your installation for any problems.  (also to avoid shipping hassles if you have to warranty it out.)  So the same thing applies, if they had done the R&R they couldn't blame you on that switch.

Still though, blaming it on the switch is BS.  It is indeed the park/neutral safety switch and reverse light switch, it also controls the gear indicator in your dash cluster.
