Default 3rd gear gone???

Well on the way home from san francisco sunday night, about 170 miles from home...the truck decides all of a sudden it doesn't want to shift into 3rd anymore.

So we had to hit the flashers and drove home at a whopping 45mph @ 3k rmps on the I-5 south (not fun).

But that's not all...after we got off the I-5 it started acting REAL bad and wouldn't hold rpms for anything. So finally we got about 3 miles from home and while in "gear" the truck wouldn't move...at all.

So we called a tow truck to get it home and after about 15 mins of waiting I decided to start the truck to see if any improvement and it started to go again.

So my question is: Is my transmission done??

It's an 05 VHO LQ9 and the trans is a ??? 65e or 80e? someone help me out there plz?

The truck has 83k on it and was purchased used 3 months ago. I have a feeling this won't be under warranty any longer because of the mileage so I'm gonna have to eat this one...

Any help would be appreciated.

i guess a TC or pump problem. Did it have a stall in it.

Obviously the tc would bust the pump if it failed.

Thats just my GUESS

Its not an 80e, I would assume 65e

Your 3-4 clutch has failed, Debris from it stoped up the filter, When you turn the truck off fluid from the converter drains back down and temporarily clears the filter, Then it will move at least till the filter clogs again and the answer is yes its done

Either way the unit will be rebuilt. If you have a local guy that you trust go that route. If not feel free to give us a call I'm sure we can hook you up. Vince
