MA5 5-speed to 5.7 hemi?

Not to hijack as this may be relevant to your search for an inexpensive manual transmission option. Have you given much thought to the later modular mustang transmissions?

The T45/TR3650 are on my list of possibilities(providing i keep my car, long story).

The T45 is basically a 5spd T56 and shares some internal parts. They are suppose to be buttery smother shifters. It was the basis for the Keisler RS transmission. The Company theT45source.com has an adapter plate to ditch the integral bellhousing and bolt it to a TKO bellhousing.


mThe trans looks pretty narrow and companies like Hanlon/promotion claim to have versions that will handle 700hp. Stock is rated at 350-360(correct me if i'm wrong) and people have gotten by with more providing they stayed off the slicks.

Then there is the tr3650, its bigger(by how much is unclear) and the adapter plate is a little more involved because you need a 01-04 trans with an 05+ input shaft. Astro performance has one they rate to 1000hp and 700ftlbs. Stock rated at 360tq or 365tq


Upside is that either would bolt to a TKO bellhousing and allow you to use a 130T flywheel. Downside is that its all unknown territory. I don't know the diameter of the input shaft for the pilot bearing, and fitment in the stock tunnel is a guestimate.

Well, I do appreciate you listing some alternatives. I am familiar with everything you mentioned as I have followed the OD tranny market for at least a few years, throughout the development of Keisler's latest offering. Fitment-wise they may be slightly better, although cost wise I don't think they will come anywhere close to what the MA5 can currently offer. A little extra fabrication with an overall significantly lower cost is an acceptable compromise for me. Unless something were to "rear its ugly head" and make the swap implausible, I don't know if I see myself pursuing anything otherwise.

Right now it's looking like...

MA5 Transmission
3.9L Dakota Bellhousing and clutch fork
AX15 Bearing Retainer
11"/143-tooth 5.7 hemi flywheel(drilled for 10.5" clutch)
Jeep slave cylinder with advance adapters hose kit
Undetermined clutch master with Dakota angle adapter(not sure year?)
GM 26-Spline 1.125" clutch and pressure plate
Custom pilot bearing

I think that's bout it for now.
