I got my '86 2.8 gt with a 4 speed going today that has been sitting a long time. My clutch is barely there and I had such good luck with Rodney Dickmans clutch slave cylinder on my 2.5 '88 5 spd. Izusu, i'd thought I'd get one for it but I can't find it in his store online. I found a '84 Izusu one and a V-6 4 spd. Muncie but no 4 spd. Izusu. I looked at my '87 gt with a 5 spd. and it looks a lot different than my 1986. I'm sure my '87 is a Getrag. Theres a dip stick and cables are not side by side on the 5 spd '87. I've been away from fiero's for awhile so I wondering if I'm forgetting something about how to I.D. the tranny's. Did they not make a Izusu 4 speed in '86 and do I have a Muncie? thanks for any info....jesse

The slave for the 85 and 86 V6 Muncie 4-speed is the same as the 85-88 5-speed Isuzu used in the 4 cylinder cars.

So there is no v-6 4 speed Izusu transmission only Muncie.Thats what i'll order than thanks!

There's no 4-speed Isuzu transmission at all. All the 4-speeds (both 4-cyl and V6) are Muncie gearboxes. However, the slave cylinders for the 4-speed Muncie and 5-speed Isuzu are interchangeable.

The aluminum master and slave cylinders are of much higher quality than the steel ones. Which will rust and fail in short time. I've replaced my steel ones at least twice front and back and going to need to get the aluminum ones next.

I know I never had a better clutch with so much pedal movement as when I got a alum one from Rodney Dickmans store about 10 years ago with the double seals on my '88 2.5. And this '86 is almost all the way to the floor with hardly any movement to make it engage. I think I got confused when I went to order one last night as I thought there were 4 tranny types, a '84 izusu,'85-88 izusu,muncies and getrags. Now I know. This is always my favorite place to ask and get fiero questions answered, thanks guys.
