Out of interest, where did the tremec part of the rumour originate from? A10 is easy to understand as it’s all off the shelf OEM mustang parts but tremec harder. The gt350 version isn’t geared right for a street coyote, and isn’t designed for high torque, although I understand the tuners have proven it works on boosted cars for ages. The magnum which does handle torque and could be geared right with the correct gear set and final drive would require investment in a new prop shaft being manufactured etc. It’s hard to see this investment being made for a limited run model sold at a relatively low price point. If it happens my money would be using the gt350 spec parts and a suitable final drive to gear it down a little.
