I got you Hotrod!



Earlier SM465
The earlier era of the SM465 include the 1968 - 1978 transmissions. There were both 2wd and 4wd versions. Internally, they are identical to each with the exception of the transmission mainshaft. The 4wd version of this mainshaft (or "output shaft") has a 10-spline output with a 2-5/8" stickout and an accompanying 4wd adapter housing. The 2wd version has a 35-spline threaded mainshaft compatible with a driveshaft yoke, and accompanying 2wd style tailhousing.

**************"The 4wd version of this mainshaft (or "output shaft")".****************:lol:

Good catch there son !!! I had never heard the output shaft reffered to as the mainshaft until you said it. Good info on that link. Anyone doing a SM465 conversion needs to familiarize themselved with that info. :High 5:

What trans are you disassembling??? Do you have a clutch spring compressor yet? There are several differant types. I happen to use the Haggerty Press type. I also need to find a distributor of Haggerty presses cuz I been having to improvise doing 700r4s since my haggerty press doesn't have the long fingers for the input drum. I gotta buy some more arms for it. Or find the ones I had. Stupid me, lost them. :idiot:

I thnk I'd avoid the $39.99 one cuz it looks like you'd have to remove input shafts to use that one. The $99.99 looks to have locking lugs so you could use it and not have to remove input shafts and also looks deep enough to get into the 700r4 Input drum.

I know. I paid like $79 or $89 for mine way back when. I like it cuz of off all the adjusments and the hole in the center of it. So if you use it on a workbench, just drill a hole in your workbench top so the input shafts can go thru it. There is no reason to remove the input shaft from the direct drum when rebuilding a trans unless you are upgrading to a hardened shaft.

Nope, to damn expensive. I just use my workbench and have the trans vavlve body facing up, it will rock to one side of the other which is fine, where ever the bell housing decides to hold it. I've done hundreds of transmisisons and never use a holding device. Sometimes a bit tricky but it can be done without. I have also used a table with a hole drilled in it before too, so the output shaft goes thru the table, and I can gentrly drop things in place. The Turbo 400 has a set of drums that are tough to put in if its not upright.
