Not only will the quad 4 transmissions not bolt up, I dare say that it would be exceedingly difficult to adapt one to small metric pattern. I have considered adapting the quad 4 bellhousings, but they are too dissimilar to be worth the effort.
ive learned that they will work, but it must be a 2.8 or a 3.1 is this correct? how are they better? stronger? whats the advantage besides avalability?

Late Getrags use stronger differential gears and use more modern metallurgy. You will need Rodneys shift bracket conversion kit and a speedometer adpater module but its a bolt in.. Seems like every week we have one or two Getrags blowing apart. IMO, the Fiero Getrag is a very light duty transmisson. I can lift up one with ease so I'm guessing that the thing only weights about 60 -70 lbs . As time goes on I would say that most Fieros will be going over to the later Getrags or even to autos.

they weigh about 95 lbs and they are not that light weight as you always seem to be implying..they are just old and worn out ...a rebuild and cryo can do wonders for strength just like it does for a 4t65 hd

if you do not want to get rodneys conversion ..you could take your blown trans apart and take the Fiero shift shaft and put it in a FWD v6 getrag and use all the same shift arms for the fiero you already have

Absolutely. I have been running a 93 Cavalier Z24 3.1 V6 Getrag for 3 years. The 92-94 versions have an internal hydrailic throwout bearing and a reluctor VSS. A $75 dakota digital unit will make the VSS compatible to the fiero and cutting/reflaring the stock fiero clutch line will get the hydraulic throwout bearing to work as well. You will want to check the clearance between the throwout bearing the pressure plate fingers to ensure the bearing will not over-extend (it will come apart and new ones cost 100 to 150).

i might have found a 92 baretta trans what is needed to get it to work, can you tell me more about the hydraulic TO bearing? do you use a fiero slave? -----can you?---- mine is new with under 40 miles on it
hod do i check about the distance from the To bearing to the pressure plate fingers?

if your trans uses the hydraulic TOB, then you don't use any slave. The slave cyl is built into the TOB.
