Tropical36: You're probably right. Somewhere in the literature, I thought that I read that it had the Allison Transmission. Since you brought the subject up, I thought that I should go back and look at the Factory Manual for the chassis.
In the 7th chapter on transmissions it calls it a Hydra-Matic 4L80-E.
So nothing special other than it shifts just fine.
I've been under it once or twice and I seem to remember that it had a coil spring front end suspension.
When I got it and drove it back to the house all the tires were low, but other than the front end feeling a little loose it was fine.
Since then I've pumped the tires to 90 psi and now I seem to have a wobble at about 40mph.
Looks like I might need some front end work also.
On the other hand since I brought it home a local shop has replaced the Hydro Boost Unit, The Power Steering Pump, and the Master Cylinder. I want to check underneath and make sure that they bolted the steering gear links and arms back solidly before I have any expensive work done to it.
