The secret may be hidden in your Jeep's serial number. Not sure, but research the digits on your VIN on <a href="http://www.specialtyparts.com/vins" target="_blank">www.specialtyparts.com/vins</a> and you might get lucky that way (and find out other cool info on your rig).

Pretty good info to be found here - I agree with Jim, it's probably a T-176.

if this is a t-176 does anyone know of an aftermarket shifter for this tranny one that might give it a shorter throw than stock???

AMC was in the habit of putting the T176 behind its 304's, and the stock manual tranny behind the 304 in 1980 was a T176. So, I would guess that you do have a T176. I believe 4wd hardware has an aftermarket shifter that claims to reduce the throw on the shift, but let's face it, you're looking at a might long stick going through a pretty big arc. You can always cut the shifter off...

I agree it s a T-176. The other 4-Speed offered that year is the SR4 Ford Tranny, which was used standard behind the GM 151 4-banger, and (unfortunately) behind some of the 258's

The SR-junk, I mean SR4, you can easily tell, it is an aluminum case, and I believe it has some "fins" on the case. The T-176 is a cast iron case.

sr-4 is definitely crap... i wish i had researched more and stayed away from it when i bought my 7. i had the reverse fixed 2 weeks ago and it pops out again... good thing the mechanic says he will "stand by" it...

That's not too big a deal that you got the SR4, KG4PAM, you have the Dana 300, and swapping a new tranny in is pretty easy, you may need your driveshafts retubed though. It could cost a little bit to do it, but I sold an SR4 on Ebay for $172, not including shipping, so you could sell yours and get some money back on it.

I am a little confused. I have what I have been told by the tranny shops around here is a T-176. The code off of the casting is what was used to identify it. It has an aluminum case. It is currently not in a 1980 CJ-5 with a Dana 300 transfer case. Not in it, 'cause I am fixing a whole buncha' stuff!

Are you positive it's an aluminum case?

If it is definitely an aluminum case, then it is not a T-176, it is an SR4 or something else, like a T-4.

T-176 is a cast iron case, no bones about it.

It either has the wrong tag or was identified wrong.

Yes, it is definately an aluminum case. And, the number is not just on the tag, it is cast into case as well. After I wrote the above post, I checked out the link for Jeep Transmissions that is listed towards the top of the list, and it shows the T-176 with the 2604203 casting number and says that it is an aluminum cased transmission. That seems consistent with what I have. Now to get it back inside of the Jeep, instead of sitting on the shop floor! Oddly, they don't seem to do much good on the shop floor, just take up space. Question, though. Is it worth changing the yolks on the dif from the strap type to the u-bolt type?

I personally think it is worth it. I have seen many many strap yokes blow apart from hard driving, LOL. I have never seen a U-bolt blow apart, usually you will shatter the yoke before blowing apart the U-bolt. <img border="0" title="" alt="[Wink]" src="wink.gif" />

I'm gonna check a bit on that tranny. You peaked my interest a bit, LOL.
