72 Charger Posted November 28, 2015 Share Posted November 28, 2015 Hi all im planning a build using the Allison Aircraft engine for a Rat Rig . I wanted to know what gearbox would best suit it? Quote Link to comment Share on other sites More sharing options...
Junkman Posted November 28, 2015 Share Posted November 28, 2015 A Fuller. Quote Link to comment Share on other sites More sharing options...
Crazy Ed Posted November 28, 2015 Share Posted November 28, 2015 Maybe surprising, but many of the only slightly modified Powerglides could do the job. Quote Link to comment Share on other sites More sharing options...
72 Charger Posted November 28, 2015 Author Share Posted November 28, 2015 Im not to savey with gearboxes which trucks would I find a Fuller or a Powerglide Quote Link to comment Share on other sites More sharing options...
10thumbs Posted November 28, 2015 Share Posted November 28, 2015 Hi Dave, a Powerglide is a 2 speed automatic Chevy trans. Very robust. The Fuller deal I'm not sure about, but then again any truck-type trans would probably work, unless you're going for a perfect assembly.Google is your friend.

72 Charger Posted November 28, 2015 Author Share Posted November 28, 2015 Thanks Michael I did look on Google at the Allison engine but didn't think about the box Quote Link to comment Share on other sites More sharing options...
LDO Posted November 28, 2015 Share Posted November 28, 2015 Jay Leno has a couple of cars with huge engines (aircraft size). They both use Allison transmissions, as used in Greyhound busses. What does an Allison transmission look like? Heck if I know. I'd guess it's the same for most of us. Use a trans from a big rig kit.Where are you getting a big Allison engine? FYI- Airfix makes a 1/24 P-51 with a Rolls-Royce Merlin that is not bad at all. You could get a couple of turbos off a larger scale kit and make an induction system like on pulling tractors or old hydroplanes. Quote Link to comment Share on other sites More sharing options...
Ace-Garageguy Posted November 28, 2015 Share Posted November 28, 2015 (edited) Where are you getting a big Allison engine? Probably this one, re-released many times in various packaging. For good info on Allison transmissions, ask over on the big-truck forum. Edited November 28, 2015 by Ace-Garageguy Quote Link to comment Share on other sites More sharing options...
Force Posted November 28, 2015 Share Posted November 28, 2015 The AMT Kenworth K100 Aerodyne and Tyrone Malone race trucks has Allison auto trannys, and I have seen them from a couple of resin casters. Quote Link to comment Share on other sites More sharing options...
72 Charger Posted November 28, 2015 Author Share Posted November 28, 2015 Thanks guys that's very helpful. Lee I had thought about the Allison transmission for it and I do have the AMT KW that Hakan speaks of .Yes Bill that's the one Quote Link to comment Share on other sites More sharing options...
LDO Posted November 29, 2015 Share Posted November 29, 2015 Oh THAT Allison V-12. Forgot about that. It would be cool to see a pair of those on a pulling tractor. Quote Link to comment Share on other sites More sharing options...
