The Stovebolt Site Forums The Shop Area Driveline Auxilery trans on 54 3600 4 on floor. YES OR NO ???

Hello. Was thinking of putting a auxilery trans on my 54 3600 to get a few more MPH. Has anyone done this? Is there another way? Open for any suggestions or ideas from those who have dealt with this. THANKS.

First get some faster gears for your rear axle.

Another option is a 5 speed overdrive. The NV4500 would be a good choice. A T5 would also work but is kind of light weight in comparison.

The auxiliary will be heavy, need crossmembers and mounts, shifter, and both a new and modified driveshaft. Plenty of work and added weight, possibly expensive depending on your luck finding one and how much of the work you can do.
Don't choose an auxiliary transmission because it's a smart choice, because there are easier ways to go faster. Do use one if you want an auxiliary just because, they are interesting, unusual, and functional.

I have a 4 speed auxiliary on hand for my 1 ton when time allows.

Thank you Grigg, you have made up my mind. I looked at the tech tip you posted and that looks like the route I'll be taking.

Be sure you have enough frame length to get the driveshaft angles right. A Brownie takes up a lot of space, and you're likely to end up with short driveshafts at oddball angles- - - -lots of vibration and/or rapid U joint wear possibilities.
