Colorado\Canyon 5-speed swap

The MA5 2WD 5-speed out of the GM Canyon\Colorado pickups may be an interesting T5 alternative. They are closely related to the Jeep AX15 and Toyota R150 5-speeds. Todd Kozak of Kozak Automotive was kind enough to send the following info about them, some pics and some info about a project he and a buddy are involved in:

"Greg, the stock THM 350 mount does indeed bolt up to the MA5, although by the looks of it about 1 inch will need to be sectioned from the total height of the mount to properly orient the trans on the crossmember. The 4 speed pictured is a 1970 vintage Muncie M20 with a Pontiac A-body shifter attached to it. Some floor ' clearancing ' may be necessary but in my opinion not too much. The MA5 shifter is closer to the center of the driveline tunnel , so the opening would be re-located slightly to the right. A good friend of mine is going to put it in his 64 GTO , of all things an original tripower 4 speed car. When I ordered the (Novak) adapter last week, the guy at Novak told me they had a customer who had an AX-15 behind an LS1 in a Jeep and it lasted for 6 months. I'm sure they were off-roading it and pounding on it. We plan to put the MA5 into service behind a 400 Pontiac which has more torque output than the LS1.However, it will be street driven only so it may prove to be a good swap. Time will tell. The MA5 has a 1 1/8 inch diameter 26 spline GM input with 0.668 pilot diameter (Muncie, Borg Warner ST-10, T-56) and 27 spline GM output (TH350, Muncie) shafts. Check out the Muncie 4 speed comparison pic. Use a Novak adapter on the front of the MA5 to bolt it right to a conventional Chevy bellhousing or BOP bellhousing, using all your original clutch linkage etc."

Todds direct email is:


PS. I forgot to mention. The bellhousing that comes with the MA5 will bolt directly up to a 275HP GM DOHC 4.2L I6 out of the Envoy\Trailblazer\Bravada. Also, the MA5 uses an electronic speedometer output. Gear ratio's are: 3.753 2.26 1.37 1.00 0.729

Todd sent a pic of his AR5 hooked up to a BOP bellhousing with a Novak adapter. That's a Buick 350 in the background. I guess he's had a change of plan.
