I have had nothing but problems with the stock fiero isuzu transmissions. It seems everyone of them I got were abused, so I decided to swap a grand am 5 spd. I didn't find too many pictures to help finure out what I needed to do to get it to swap over. So I took a few pics so others don't have to search like I did. This transmission came from an 89 Grand Am with the 2.5 and not the 2.0. I guess the gear ratios are the same. The shift mechanism cannot be rotated and the clutch arm is too short. Both are an easy fix if you swap them from the old isuzu. If you wanted to use the clutch slave from the Grand am(or Cavalier/Calais), then you don't have to swap the clutch arm. I decided to use the stock clutch slave to simplify the swap. I had to swap the clutch slave mounting bracket also. All in all it was a really easy swap.

All of the internals are the same. If you scroll down to half way you can see the gear rations for the 82-89 Grand Am Isuzu 5 Speed.

Not at all. It does very, but the medium price range is between 250 and 400. I got mine for a steal at 100.

Ah, ok. So you are saying this is another source for Isuzus, not that they are beefier. Still, maybe they did some improvements so even if they were beat on they would last. I've seen some that were pretty noisy but for the application they seem to last.

Good info! + for you.

Isn't it the case that usually gives up the ghost? That was the reason they began casting enforcing ribs into the cases in 85. That case actually looks stronger on the outside, especially around the output shafts. That's some pretty heavy gusseting. It's most definitely stronger than the 84 4-speed transmissions.

Outside of putting a V8 on one, is there a common failure for the Isuzu? The only solid failures I've heard of were from exceeding their torque spec. Behind the 2.5 they seem to be bullet-proof. I know, that just doesn't sound right does it.

I have seen many pics where 2ND gear had been chewed threw when it blew.

You are thinking of the 4 speed Muncie which was in the 84 and returned in 85 with additional ribs in the case. The 5 speed Isuzu in the Fiero was the same during it's entire run of 85 to 88.

Yes I was, but I was also referring to later transmissions. That ribbing looks wider and deeper than what I remember on even the Getrags
