[chevy wrangler]

4l60 or the newer 4l65. easy to spot. 4l65 has removable bell housing like a ford tranny or any stick tranny.

tcase should have a tag on it. or cast in the case borgworner. chevy has started to switch over to them. if older new prosses. it will have a red round tag on the back in the middle area.

i think the tag is blue i'll check it tomarrow, oh and thanks

4L60e and either an NP246 if its pushbutton or the NP263 IIRC if its floorshift.

 

[chevy wrangler]

push button with
4lo
2hi
4hi
they should have a neutral button but its a light

 

[bggrnchvy]

I messed up, the NP263 should be whats under your truck, the floor shifts should be the 261.

If I'm not mistaken it could be the np241.

being a Z71, it could have a 4L80E in it. i've looked at a couple recently that had a 4L80E and a 10 bolt out back. 16 bolts = 60E, 17 bolts = 80E

 

[chevy wrangler]

umm so a 10 bolt is a 4L80E?? it has 10 bolts

They stopped using the NP241 on the NBS trucks.

No half ton, being the only GM truck factory with the 10 bolt rear, comes factory with an 80e.

i've seen at least 10 trucks like this, one of them being my buddy's 94. ironically, ALL of them that i have seen were extended cab shortbed Z71s.

No, he is saying 16 or 17 bolts in teh tranny, not 10 on the rear end.

Its probably not a 4l80E, but theres a chance...
