M-22 or Super T-10 ?
 

I am going to look at a 4-speed next weekend and the guy can´t tell me for sure what it is. The casing is made of aluminum he thinks.

Cast on the passenger side: 1304065903 W.G.DIV FPC2 (with the P lower than the rest) 1/8/1975

Cast on the driver side: B.W.13.04.066.901
Stamped on the driver side: WB2552

Cast on the cover: 13-04-097-90# and under that G297#

<font color="blue">I would say it's a "Borg Warner".
Whether it's a super t10 or not - https://www.yenko.net/ubbthreads/imag...lins/dunno.gif</font>

Re: M-22 or Super T-10 ?
 

I don't see anything there that looks like a Muncie number.
The best place I have found for identifing Muncie's is at www.4speeds.com then look for Muncie. Great info here. It helped me ID my M22.

Re: M-22 or Super T-10 ?
 

An easy way to visually distinguish a T-10 from a Muncie is to simply look at the side cover. A Borg Warner T10 will have a curved bottom on the side cover, while a muncie will have a flat bottom on this cover. Muncies are always aluminum case, while some Borg Warners (not all) came with a cast iron case.

I was going to thank you guys when I received the transmission, and I got it today. Thank you !
It came with a 62-67 Chevy II scattershield and a Mr Gasket Pro shifter.

looks like a slick shifted ST-10 with every other tooth ground off the speed gears...Crash

Re: M-22 or Super T-10 ?
 

Hey Crash... Did you ever hear of a crash box?

Re: M-22 or Super T-10 ?
 

Something tells me thats how he got his name !!!

Re: M-22 or Super T-10 ?
 

<font color="blue">From the close-up I did on the clutch disc
you recieved with the trans, I would sat it is a B-W T-10.

It looks like the disc is a 10 spline (correct me if I'm wrong),
&amp; the ST-10 should be a 26 spline. </font>

Re: M-22 or Super T-10 ?
 

The geartoth-angle is the same as in an M-22, and it has a 26-spline input shaft.

Re: M-22 or Super T-10 ?
 

I could be wrong but the angle of the gears that you posted the picture of do not look like M22 gears to me!M22 gears are not cut at that much of an angle.The gears you are showing look different somehow,looks maybe like they have been modified or something but don't look like M22's to me.The 26 spline shaft is a super T10 and the side cover is a borg warner,are there any grooves on the input shaft.A M22 has no grooves on it.I do not believe a set of M22 gears will work in a borg warner trans!You are showing a borgwarner trans in the picture!

Re: M-22 or Super T-10 ?
 

From all the pictures you've posted, you have a 2.43 S series ST-10, not a Muncie at all... M-22 gears have a staighter gear angle, but not perfectly staight across...
Yes I have heard of a crash box, I have several in stock... Along with over 100 Muncie cores, over 50 ST-10 cores, 10,or 12 Nash 5-speed crash boxes, and over 300 Hurst shifters...
As for my name, I had a bad run of luck with people hitting and crashing my cars... I lost track after 20 accidents, not counting the one in Mexico... Crash

Re: M-22 or Super T-10 ?
 

Damn I was wrong !!! I figured you were just plain ole crash box CRASH !!!

Re: M-22 or Super T-10 ?
 

I didn´t say it had M-22 gears in it.
Can someone post a picture of M-22 gears ?

Re: M-22 or Super T-10 ?
 

From "Corvette by the numbers" by Alan L. Colvin:
"The Borg-Warner T10 4-speed was introduced in the Camaro and Corvette in January 1974." "By 1974, the muscle car era was basically over, and General motors decided to outsource transmissions for those few models that still needed a high performance gearbox." "This version is considered the sixth, or final, design, and is more commonly known as the Second Design Super T10." "The Borg-Warner 4-speed offered two new gear ratios, a low wide 2,64:1 and low close ratio of 2,43:1"

This one is 2,43:1 close ratio built in 1975 with a Norwood VIN on it.
What does that first #2 designate ?

Re: M-22 or Super T-10 ?
 

I agree, the ST10 gear-angle is somewhere in between M20/21 and M22.

Re: M-22 or Super T-10 ?
 

The first 2 is GM Division designation
1-----Chevy
2-----Pontiac
3-----Olds
4-----Buick
The 5 after the 2 is the model year...
So your trans came out of a 1975 Firebird built at the Norwood plant...Hope this helps...Crash
