Re: transmission, please help.
The tech who said ign switch has nothing to do with trans problems is clueless. There is a service bulletin about it. Ign switch can drop ign 1 voltage to the tccm and cause all kinds of problems. Causes the trans to go into limp mode when voltage is lost

Re: transmission, please help.
I fully agree that is why Ireally want to get to the bottom of this with this forums help. The dealer in question is way up north from where most of you are, which is where I am from. Edmonton, Alberta, Canada. It's called Southgate, I couldn't believe what I was hearing the first time around. If that's the kind of attitude at all of GM's operations, no wonder they are in trouble.

Re: transmission, please help.
So I changed the switch this morning and problem persists, f&*k! Do you guys think it's possible I snagged something on a branch or a tree, there were a few bushes I had to get through to get to the quad site?? If so where on these trucks would I find the connectors that would cause this?

Re: transmission, please help.
No, that is one of the problems. At least then I would know the diagnostics are picking something up. I will go and get a scanner today and see if anything pops up. In the meantime any suggestions are greatly appreciated. Thanks

I am in Edmonton, Alberta, Canada, I don't know how many members are from around here. Also I just had a thought, maybe it might have something to do with it. The day this happened, I fueled up and forgot to put the cap on when I was towing my quads. I drove for about 15miles before I noticed it, check engine light never came on though. |

Its mostlikely gonna be a speed sensor. I cant remember if its on the back of the transmissions on these, or the transfer case.
