Input shaft spline
 

Hi all. I'm looking to convert the 3 ott to the t5 5 speed swap. I found a late 80's world class camaro 5 speed, and an early 90's s10 5 speed for the tailshaft.

This is new terrain for me, so I'm really curious, is the spline amount on input shaft universal? The seller of the camaro 5spd said it was 27-28 splines. I happen to have an old 3 speed floor tranny that has 14 splines(PO was going to install that). Also, from what I know the engine is a 350 from a 75' Monte Carlo.

Thanks,
Mike

Re: Input shaft spline
 

If "3 ott" means Saginaw 3-speed manual, it will have 27 splines, same as many GM transmissions.

Trans output shaft spline count:

Automatic Transmissions

Powerglide 16 spline
Powerglide 27 spline
Turbo 350 TH-350 27 spline
200R 27 spline
700R 27 spline
4L60 27 spline
Turbo 400 TH-400 32 spline
4L80 32 spline

Manual Transmissions
Muncie 27 spline (M20, M21)
Muncie 32 spline (M22)
Borg Warner 16 spline
Borg Warner T-5 27 spline
Borg Warner T-56 27 spline
Borg Warner T-10 27 spline
Borg Warner T-10 32 spline
Saginaw 27 spline See Muncie
ZF 6 speed 32 spline

Manual Trans input shaft spline count is typically 10 or 26. Your Saginaw is probably 10. If the T5 is 26, all you need is a new clutch disc.
