Has any one ever tried to put a ZF S6-650 transmission in one of there trucks? i would like to put a 5 or 6 speed trany with over driver in my truck, for better fuel Economy, and to Run better down the high way.

The money you spend in the conversion will outweigh the fuel savings. Did one of these fall in your lap?

I currently have a ZF6 from a 2002 Chev sitting, waiting for a transplant into my 1986 1 ton.
The 6 speed is a 2wd version, I got lucky......34000 km on the trucks odometer and I paid $1000 for the transmission. I also already had a divorced NP205 sitting around anyways.
The ZF6 is a big transmission, it's tall, long and heavy (about 220 lbs or so) and slightly worries me that I will need a body lift to even fit it under my floor. Either that or some good transmission hump modifications.
I wouldn't be looking for one specifically, in fact I would more so lean towards the NV4500 due to its size and availability. That being said, I found mine by accident and it was the same price as what people wanted for a used 4500 with more miles on it, so I wasn't about to turn it down.
I'm actually sorry now I didn't take the 8.1L that was bolted to it for the extra $1000 :-\
My bottom line I guess, if you find one cheap and in good shape, go for it. But if you have something like a 2wd half ton, there are other 6 speed options out there that would do fine.

i found one in a wreck truck 4x4 all they want is 300 for truck. it got better gears ratio and over driver i just want to know how much bigger is it them my ms465 and will my 208 will bolt to it be for i buy it.

I hate to say it, but it might be easiest to take the transmission with the t-case thats currently on it and covert your truck to a drivers side front diff.
I've seen a thread in the past about someone who mated an NP205 to the back of an Allison. The ZF-6 has the same rear end as the Allison in the 4x4 applications, so if an adapter can be done for the Allison then the ZF shouldn't be a problem either.
Therefore, if the NP205 can be used, an NP241 can be used as well. Not too sure about the NP208 though.
