I have a Muncie and I am starting a 3800sc swap. I would like to know if its worth it to buy a getrag and why. Also other than the actual transmission itself , what other expenses and work is there in converting from a Muncie to a getrag?
Thanks------------------

It really depends on what you want and how you plan to drive the car.
1st gear of the 4 speed (assuming V6 4 speed) is much better suited to a higher torque engine vs. the 282 Getrag, F23 Getrag or the F40.
The 4 speed starts to lose favor when you want to drive it at elevated speeds for long periods of time. That is when you miss having the 5th gear to lower cruise rpm and many time cabin noise volume.
The placement of the transmission and axles are the same between the Fiero 4 speed and Fiero 282 Getrag, so if you start with the 4 speed and later want to swap in the 5 speed then it isn't much additional work.

The more power your engine makes, the fewer gears you need to get that power to the road. 5 speeds are a great idea for the duke....6 speeds are a great idea for new tiny efficient motors....but for a 3800SC, I would rather not waste my time with extra shifting.

This is what matters. If you use the 4 speed you will want a 5 speed just for this reason.

The shift & select cables are different.
The Getrag shift linkage at the transmission is different
I believe the shifters are different
The transmission mount brackets are different
The VSS connector matches up
Also, be careful which version of the transmission you get... Fiero Getrags only came in one flavor, but the Grand Prix with 2.8 (and 3.1?) had different gearing.
Also, there are several versions of the Muncie: 3.32, 4.10, 3.65 and FrankenMuncie[This message has been edited by Will (edited 05-19-2014).]

Wow! Thank you all for the immediate responses. I thought the 4 spd might have been more fragile than the getrag and that's really what I am worried about. I don't plan on doing extended highway driving with it so ill stick to my Muncie. This forum is AWESOSME!
Now if I could just find a step by step for my swap.------------------

You could easily break either with a 3800 swap. The 4speed is slightly weaker.

Yeah, the 4 speed trans is a bit weaker, but none of the available transmissions are rated for a 3800, so they're all out of their element. You can break anything if you're dumb.
