So Will, are you saying since I have a 6# flywheel on my tilton setup I won't blow a transmission?
If you need any contacts to adapt stuff to your Northstar let me know.

I just measured this little guy at 80 ftlbs of break-away torque.The Dark Side of Will wrote:
Jeff is about to disassemble it for me. I'll ship the gears--along with a 3.94 R&P set--to a specialist--probably Liberty Gears ( http://www.libertysgears.com/metal%20enhancement.htm )--for cryo, maybe tempering, shot peening, ISF/REM polishing, etc.
Once that's done and Jeff reassembles, I will check it again to see how much the polishing dropped the break-away torque.
When I install this one and remove the Gr8Grip, I'll check that unit for comparison.

This is the setup I used to measure preload:
Re: Getrag 282 insights
I'm trying to combine one of the new Opel Silhouette (quad 4) NVG T550 transmissions with my original Fiero Getrag 282. I wanted to use the Fiero first, second, and fifth gear ratios while using the Silhouette third, fourth, reverse, and final drive. Of course, I'm also trying to use as many of the new parts like synchros and bearings.
Everything seems pretty straight forward with one exception. The output shaft has a different bearing design for first gear, and it's not immediately apparent if the two designs are compatible.
This is the 282 output shaft. Note the diameter of the first gear bearing surface (next to the final drive gear).
This is the 282 thrust bearing that first gear presses against and the roller bearing that goes under first.
This is the T550 output shaft. Note the diameter of the first gear bearing surface (next to the final drive gear) is stepped down to accept a bearing with larger rollers while using the same gear bearing surface ID.
This is the T550 thrust washer that first gear presses against and the roller bearing that goes under first. You can see these are significantly different designs. The ID of the thrust washer is the same as the ID used in the roller bearing from the 282, and the washer thickness is very similar to the stack of bearing assembly from the 282.
The critical dimensions seem to measure out very similarly with my cheap digital calipers, and I'm expecting to be able to use the 282 first gear with the 282 thrust bearing on the T550 output shaft with T550 first gear bearing.
Has anybody tried to use a 282 first gear on a T550 output shaft like this? I haven't been able to find any discussion on it, and I'm a bit nervous to experiment with this gearbox. I was hoping somebody else was the guinea pig instead of me.

Re: Getrag 282 insights
I haven't put it together yet, but I have that style bearing and thrust washer for my 3.94 output shaft. I anticipate no problems.
I didn't know that was T-550 part... I thought it was a 3.94 part.

Re: Getrag 282 insights
I don't have any 3.94 282 or other T550 gearboxes to compare, so you could be right; I hadn't considered the possibility as the service literature (published for the earlier 282s) I have shows the thrust bearing only (so I assumed they omitted this and used only a thrust washer as well as the updated first gear bearing later). Where did your 3.94 shaft/bearing/thrust that looks like mine come from? As in, what vintage transmission?The Dark Side of Will wrote:I haven't put it together yet, but I have that style bearing and thrust washer for my 3.94 output shaft. I anticipate no problems.

Like I said, it *looks* like it will work. I'm hoping somebody else has actually tried it to confirm or deny.

Re: Getrag 282 insights
Pretty sure mine came from a Quad4 application, but I don't remember what year.
The part number for the 3.50 first output gear is the same for the entire production run, right?

Re: Getrag 282 insights
I guess I should also mention the 282 first is a 3.5 and the T550 is a 3.77 in case that affects bearing/thrust designs as well. I'll see if I can find part numbers for Fiero and later T550 applications to compare.

Re: Getrag 282 insights
Can you confirm that 3rd is the same on the Fiero 282 as the Silhouette T550? (1.38:1)
Re: Getrag 282 insights
Ratios I measured in this Silhouette export transmission are:
1: 3.77
2: 2.19
3: 1.38
4: 1.03
5: .80
Final: 3.94

Re: Getrag 282 insights
Thanks. For reference, the Fiero Getrag 282 (MG2 option code) is:
1: 3.50
2: 2.05
3: 1.38
4: 0.94
5: 0.72
Final: 3.61
So for your hybrid you're looking to use 4th, reverse, and final from the Silhouette to get:
1: 3.50
2: 2.05
3: 1.38
4: 1.03
5: 0.72
Final: 3.94
That looks good! I certainly wouldn't mind a shorter 4th for mine. That said, a 3.94 final might make the difference alone.

Re: Getrag 282 insights
I have 3.50/2.19/1.38/1.02/0.72/3.61 in my car now... the short fourth makes a surprisingly big difference, and really helps out the top end, especially if you top out third too regularly...

Re: Getrag 282 insights
Will I thought you told me the first and second gears shared something and couldnt' be interchanged? I think the 3.77 first is rediculous and would want the 2.19 second and 3.50 first but I could have sworn I remember reading that wasn't possible. Maybe I have the wrong pair of gears?

Re: Getrag 282 insights
I may have said that before I actually found one
There were three input shafts made:
3.50/2.05 Stock Fiero & V6 FWD cars)
3.77/2.19 W-body and minivan V6 models, later Quad 4's)
3.50/2.19 Early Quad 4 cars... I think I got mine from an '89 Beretta. It's pretty rare. I really like it, but for Steven's use it makes 2nd gear too short. YMMV. My limiter's at 7k and I just clear an indicated 60 mph in 2nd (with 3.61 final).
The only combo not made is a 3.77/2.05.

Re: Getrag 282 insights
First and second are part of the input shaft so they can't be interchanged, but most combinations were made.
I tried a 3.50/2.19 input shaft and while the 1st-2nd shift is awesome, 2nd-3rd is horrible and ruins it. I took the trans apart and built one with the 3.50/2.05 set, which is what I'm using now.
