What's my Transmission?

[jzak]

Hey guys,

So my 3rd and 4th gear syncros are gone on my 1981 Jeep CJ5 AMC 258 i6 / 4.2l , so I was looking at rebuilding it, but i'm still not 100% sure which Transmission I have. I'm pretty sure it's a Tremec T-176 , but I don't want to buy a rebuild kit without knowing for sure. I suspect it's the T-176 because its a 4-Speed found on 1980-86 CJ's, and has the same shift pattern with reverse positioned to the right and down.

Just to be completely sure, are there any model numbers that I could visually inspect on the Transmission , so I know what I have?

Any help is greatly appreciated!

Thanks!

Thanks for the link, but i'm sorry to say it's really not helping me. Based on my jeep year, It could be either the SR4 or the T-176 . I need to know exactly which Transmission I have, so I can buy the correct rebuild kit.

Thanks Anyway!

The SR4 tranny's shift pattern has reverse to the left and up towards the dash. The T-176 shift tower sits directly over the gear box. You might also have a T-4 . The shift tower sits behind the gear box on the tail shaft on that one. There's no telling what a previous owner has put in there. Pictures would help.

OP-Post up some pictures of the shift lever and side shots of the tranny.
You say the 3-4 syncros are gone-How so? How much free-play do you have in the clutch pedal??
When was the last time you check'd the oil level in the tranny or t'case???

What does the shifter cane look like? A T-176 or 177 has a straight cane, where a T-4 or SR4 has an S shaped cane but reverse between the two are opposite. Go to novak's website for pictures and descriptions.
