I just bought a 86 GT with a 4 speed. Was there only one 4 speed or two available for that year? If more than one, how can I identify that transmission.
Thanks

Just one...the M17.

Halfway through 1986 they switched to the 5 speed.

Are you positive? I'll accept the fact that the 5 speed came later, but im pretty sure they offered both in 86. Considering mine is an "86 1/2" and yet I have the 4 speed muncie.

BTW, the 4 speed is considered the strongest, tho the getrag is easily a smoother shifting transmission.

The Getrag 5-speed became the standard manual for the V6 powered 86 Fieros in June of 86, near the end of the production year. Prior to that, 86 V6 manual transmissions were the M17 as Gall757 stated. You can tell if it's the proper 4-speed by looking to see if there are cable mounts cast onto the case near the VSS and also if there is reinforcing webbing radiating out from the seals for the axle shafts. The 85-86 transmission will have the webbing and not the cable mounts.

You may be assuming your car is an 86 1/2 and therefore should be equipped with a 5-speed. That's an incorrect assumption. I've owned 2 86GT's that were 4-speeds.
