I believe Bullwacker007 is right, I think he said it was a 4L80E but its not on the paperwork. Next time I'm underneath I'll have to remember to look. So I picked up the bus from the shop Thursday (final bill was $3080) and it felt alright, no noises and shifting better. But yesterday I took the bus out on the highway to go camping and 10miles later im overheating!! It was too late to get to the shop and we were pushing it to make our hike so I limped it to the trailhead. Then today we got back to the bus and over to the nearest Aamco but they were booked up till Monday. So we're spending yet another weekend waiting for the shop to open back up.
In the mean time I have been pulling my hair out trying this or that to figure out whats wrong. Nothing appears to be leaking out anywhere, I'm getting heat blowing from the vents so the thermostat (which I replaced back in Austin) should be open, I bought a new reservoir cap today but no change, Oil dipstick is black and at level so we dont have a cracked header... unless one of the hoses is collapsing I can only assume there is a clog somewhere.. but why would that magically appear right after they finish working on it? My other theory is that we aren't getting out of 3rd gear and the high rpm's maybe are making it run hot, although I don't actually know that would happen. But I can't feel it shift into overdrive (4th) and it sounds MUCH louder now than it did before on the highway, kind of has a whine to it. And I drove a back road home from Aamco where we only drove 45mph and we didn't have a problem at all, so it may just be the overdrive. I think that makes more since given we didn't have an overheating problem before I dropped the bus off.
guess we'll find out Monday...
Here's some pictures of my one night hiatus from mechanical problems..
Big Easy does not blend in well in the desert..
Because of the overheating we got a late start and couldn't make it to Geronimo's Cave.. maybe next time.
We camped here with our friend Trenton (far right) and had two visitors share smores with us before they hiked back down in the dark. Desert camping is so different than anything I've done in VA where your always under trees. It was so bright last night we could have hiked on without flashlights and been fine. It was actually the first time I've camped without a tent too (VA has too many mosquitos and I usually get destroyed without the safety of a tent), fun times.
