I came across a T-10 that has an all iron case & coarse input splines. What can you-all tell me? I can't see the tailshaft in the photo to see if it is the TH400 or Th350 size. Any idea what first gears it might be? Can't see input grooves either, but this is the first coarse spline T-10 I have seen. Strength info? Anything? Thank you.
What does it say on the case??? Is it stamped T-10* something? If it is it is an early one. Go to www.5speed.com and google it. To help ID it. Michael
cast iron case and alum. tailhousing? thats what my 65 gs had in it also came in all gm cars till 65 except chevy they used muncie after 64 Ive never seen a fine splint t-10. be careful if you are going to buy as ford also used these and the will not bolt to a gm bell if ineterested I have an all alum t-10 to sell.
The "B" is the series which also designates ratio. Not sure what the extra 1 designates. Could signify 1st design though. There were two designs. B series is 2.36, 1.78, 1.41, 1.00 Interesting that the tailhousing says "k." The tailhousing date stamp leads me to believe this is a Ford OE. I'm now thinking the two housings are from original separate trannies. 1st design supers had 10 splines; 2nd design super has 26. A "super" would probably have an "S" before the T10 (at least it does on the ID plate on mine). Source for my info : Mucslecar Review Sept. 95. I'll scan the article and post it next week.
'62 Pontiacs were one of the 1st GM's to receive the cast iron case/cast-alum tailshaft T-10. There will be a casting date on the tailshaft housing. In the racks, I have a T10 out of a late '62 Cat. It is a wide ratio version. The close ratio version seems tougher to find. Never learned how many cuts in the early T-10 input shafts, designated what(?) Historical reference: On the Muncies, they started to be used in '63 models by Chevy, in Impallas & Vettes. For '64 models, GTO's & possibly (???) higher powered Chevelles received them as well. From all I've ever come across, all production 4spd '64 GTO's received M20's when optioned with a 4 speed (no M21's). Have rebuilt quite a few of these small pin Muncies, they're not the hottest ticket stock... need some serious upgrading p -Buick... 4spd '65 Buick GS's had the T-10, believe this was the way it was through '66 model ('66 owners?). Have come across several '66 Buick big car that had a T-10, as well. Big Pontiacs '65 & later received Muncies. -Olds... have what's left of a 4spd '64 442 post car, & a good buddy has similiar '64 442 post car as well. Both of us rescued these cars from longtime owners. Both cars originally came with Saginaw 4spds. Also have longtime friend who bought a 4spd '65 442 new, it came from factory with Saginaw 4 spd. -Not sure if any late '65 442's received Muncies or not (Dave H?)... -When one reviews "who was getting what", sure seems like Muncie production was being taxed to the limit, & only Divisions 1 & 2 were getting the Muncies... :3gears: Roger
Limited experience on other brands, but the 2 Buick T-10's that I have are the Iron Case coarse input shaft design. Both from '65 Wildcats, both are 2.20 : 1 first gear, they also have 3 "rings" around the input shafts, like small indentations. That is supposed to indicate the high nickel content input shaft and gears. The 2.20:1 first gear is steep, lots of clutch slipping to get the big Wildcat moving.
And this... http://www.classicar.com/articles/T-10.asp ... I'm going to put a ST-10 in my Stage 1. I got a 904 nodular iron case and billet aluminum mid plate from Tex Racing ( www.texracing.com ) good people, and good info. Steve, I think, told me that a iron cased billet midplated ST-10 would work with our torque monsters, but if it ever hooked, ie slicks, kiss it good bye. He said that the iron cased ST-10 was stronger than the muncie, but there was not much that can take that amount of torque... But this was b4 the new Tremec's came out. :3gears: :3gears: :3gears:
