Title: T-10 4-speed
Post by: got2haul on November 15, 2007, 09:53:49 am

Anyone running one of these Richmond Gear T-10 4-speed transmissions?  I'm looking for fitment comments.

It should fit fine.  It is basically the same as a muncie 3 or 4 speed.  I used a M22 passenger car Muncie for 7 years.  I have a Nash 4+1 that replaced it now. (Richmond bought Nash tooling)

So tell me about the Nash 4+1.  What's the "+1", overdrive or 5th?  So you're saying I probably won't have to modify the cross member?  I currently have the OEM 4-speed with granny low.

Nash 4+1 is identical to the Richmond  5 speed.  No overdrive.  5th is 1:1.  I didn't want overdrive.

You have the toploader SM465 then.  It will fit with no problems, just bolt it in and go.  The biggest hurdle is cutting a new hole in the floor.

MY 6 is a 4 speed overdrive.  OD being the 4th. gear at .71  It is the same size as a muncie, and made for our trucks.  I have 3 of them...

mm 7 was the RPO for a 4x4.  They are vary rare and I have only seen 1.  3.09 first gear with a .71 final.  It is a New Process A-833.  It is the GM cased Mopar A-833.  The non-overdrive version was the hemi 4 speed.  Looks like I will be putting one in my C-10 soon replacing the 3 speed.  I have one for the Chevelle as well.  I haven't actually driven one in a truck but I have the Mopar version and the gears are long but managable.

The A-833, in just an ancestor of the Hemi 4 speed, they don't have the same strength.  They are known for being VERY weak behind mildly built 350's.  They came behind light duty diesels mostly and were offered in 1981..  It wasn't available behind BBC's or HD diesels.
