Need 6 gears on 22re
I do a lot of highway driving and would like another gear. I know there used to be a company, I think Saturn that made Overdrives that bolt to the back of a T-case. I have not been able to find one for a Toy T-case. Has anyone else been down this road? I don't want to loose my 1st gear crawing so changing axel gearing is not what I want to do.

I've never heard of anyone making a bolt-on overdrive for our trucks but a few make bolt-on underdrives (dual t-cases). http://www.marlincrawler.com/htm/tra...ansfercase.htm
The thing to do would be install dual t-cases for the granny gears and gear the axles higher or better yet just put on bigger tires. I kind of doubt the 22re would have the power to pull a much higher gear except downhill or with a strong tailwind. What speed and rpm's are you running at now in 5th gear.

Well I am constanly running 3100-3200 rpm for 40min at 70mph or so. I would like to drop that down to around 2800 with another gear. I could put bigger tires on but then you have more weight to move around and it is a 22RE. I think it could handle another gear. Yes, I would have to downshift a bit more but it would be worth the savings in fuel and wear on the engine.

The downshifting and having to floor it to hold your speed will have a more dramatic effect on your fuel economy than the lower RPM.

22re's are made for higher RPM's, these trucks used to be just 4 speeds anyhow. BTW, my 5th gear went out on my 86 nd I just drove it in 4th for a whole summer at 70 and 4000 rpm, the 22re took it no problem. Eventually the tranny wouldn't go into gear though....

The R-series are a torque motor.. Good for low RPM. Above about 4000-4500, the torque really falls off fast.
2800 is a little low.. If you really want to gear it like that, I'd adjust my 3rds (or tire size) and use a crawler unit for the off road stuff. The 22R is going to struggle to pull 70mph at that RPM however, just due to the force of the air...
