81 F100 Trans ID

Can someone tell me what trans I have? It is a 4 speed manual and the **** indicates it is an overdrive. It looks like the SMOD, but the case is aluminum. It has the fill port on passangerside, and speedo cable on driverside.

Yes, but it doesn't seem to have the unique shift rail that the SROD is supposed to have. A mechanic told me that there was a 4 speed non-overdrive trans offered, and that it could be it. I'l post pics here shortly.

I must have typed something wrong, because it turned "shifting" to ****ing

LOL,

Crap, I was hoping it wasn't the SROD. I saw a pic somewhere that claimed to be one, and the shift rail looked like it was on the top and about a foot long.

How hard is it to rebuild this tranny?
Should I remove it with or without the bell housing?
Any other comments or suggestions?

I haven't rebuilt one yet, some say it isn't hard. I chose to swap mine out with a t-18. You can pull it out without the bellhousing, I found it easier that way.

Did you drop the crossmember to get it out, or unbolt the trans and turn it out of there? I like that it has overdrive, beause its gonna have to take on DD duties, but I wish it wasn't so weak. I'll probably take it off by itself, and then remove the bellhousing after, because I believe there is a freeze plug behind it that is leaking. I'd like to check out the flexplate and clutch while I have the trans out, what should I be looking for?

You can get it out without taking out the cross member but it isn't easy, with a tranny Jack it is almost impossible, but if you can handle he weight on your chest you can take it out manually without removing the crossmember

lol,
Yeah transmissions aren't really my thing. So what use a flexplate, an auto? Does the clutch just contact the flywheel are what? I personaly don't care for manuals, but this is not my truck.

I have the same transmission with the shifter mounted to the side of the tailshaft. Is this a specific type of T170 or what? It's proving hard to even find pictures of one with the side shifter.

Desperately need transmission part

Alright guys here's why I ask: I just acquired the original Tremec SROD 4 speed tranny and the potmetal shift turret housing on the side of the tailshaft is rotten from sitting in the dirt, so I can't mount my shifter. Can ANYBODY please help me find this part?
