This 5-Speed is out of a 2003 ZR Blazer. Can someone tell me what it is?????
The tag says Muncie, I know that much! Searched the 'net and couldn't come up with anything.
A friend calls it a T-50. What do you think??



Thanks for the help,
Mike

It would appear to be a 5 speed fully synchronized transmission, with bell housing integral to aluminum transmission case. It is similar in design and appearance to HM290, 5LM60, and NV3500 (New Venture) series transmissions, but slightly smaller. Requires some special tools to rebuild. Used in 1998 and up GM S10 vehicles with 4.3 liter engines. Also known as an M50.

T-50 is the old borg warner chevy Monza tranny from the 70's.
So far I've come up with M-50 2 wheel drive 5 speed 1998 to 2005.
M-50 is a NV3500 ,1rst gear ratio=3.490 2nd=2.160,3rd=1.400,4th=1.000,5th=0.780.
Its a medium duty trans. used in every 4.3 litre vortec S-10/blazer from 1998 untill 2003.
If you want to read up on it search WILKEPEDIA for NEW VENTURE 3500.

The NV 3550 also came in some Jeep Products. It makes a good transmission for a 4x4, I used one in my Early Bronco. Ist gear is almost a granny gear dont know how this would work on a street car. The transmission itself is actually a pretty good transmission for "SOME" aplications. I believe it is rated for up to 300 Ft Lbs of Torque.

Thanks to all for your help. The tranny is going in my '34 Roadster behind a
'95 LT-1. The engine is stock so, the tranny should be OK.
Thanks again,
Mike.
