Default noob 4l80e question

Hi Guys,
I'm having a hell of a time finding a 2wd 4l80e trans.
am I even looking for one or are the masses using the 4wd version with some sort of modding?

Thanks
Warren

car-part.com
ebay.com
craigslist.com

I picked up a 2001 4L80e from a 2wd 1500HD for $500 on craigslist complete with lower cover, correct flywheel and converter. It had 98K miles on it and is working fine. You can get a good deal if you can be patient and check around. Just figure whatever you pay for one might end up being what you pay for a core so be careful how much you end up investing in one.

Good luck.

4wd will need a new tailshaft for 2wd. You can use an LS-style 4L80 99+ or an older 4L80 with the 6-bolt bellhousing for the older small blocks. The extra bolt won't make a difference but you'll need the correct flywheel and torque converter. If you have a 4L60, you can buy a converter that works with your flywheel.

After reading the stickies and the how-to post here on the site. The tranny he used is the exact one i can buy. 02 model from a 2500 hd pickup.

He didnt mention anything about swaping tailshafts.

I know the converters are diff. Wiring isnt a issue.

4wd has a transfer case bolted to the rear of the transmission. There is no way to make that work in an F-body or 2wd application without changing the tail out to a 2wd one. If you have the 8" aluminum cone on the rear without the transfer case, then it is a 2wd transmission and not a 4wd. If you got a heck of a deal on a 4wd tranny and you are using it in a 2wd, you will have to change the tail to 2wd.

Where in Canada? I live in South Louisiana and I had a Toyota 7MGTE shipped from Montreal for $300 IIRC. If you are anywhere near Michigan, it may be worth a drive across the border. I don't know how easy it would be to take back, but I see them go for beans in the Great Lakes states a lot. Not sure if that helps, but it's all I've got.

thanks for the info! any round about idea what the tail shaft cost to change it out?

I can get this 02 tranny with two sets of guts and a shift kit for 450. and hes local. but if its not worth swaping parts, I may just buy one already done and ready to bolt in.

I've seen the components on flea bay new for pretty cheap (I think they are anyway) but I think you have to install the new tailshaft and that's best left to a shop and I don't know for sure what it would cost. I would call around for a quote. I think a used output shaft is $50, plus seals, bearings and labor. You're looking $200-250 if it can be done pretty easily.

I'd say get a quote on changing it over with and without a rebuild. You may be farther ahead going through it and changing the tailshaft at the same time.

When I got mine for $500 I figured that if it was another $1200 to rebuild, I'd still be in it about what I was going to spend on rebuilding my T56, buying a new clutch and all new hydraulics. I put it in assuming I was just test fitting and crossed my fingers it would work. It's been running for about a week and so far it's been fine. I'm digging the A4 with the M6 axle (3.42) but not my MPG. 18.3 best so far.

I'll probably go 9" with a 3.50 gear set when I put my LQ9 in. I almost never road trip so my DD mileage is the same, and the handful of trips I might take where it costs me MPG won't offset the grins from the higher ratio. The only thing I didn't care for was that my T56 in 5th (0.75) at cruise would be around 22mpg. So I'm hoping my average comes up some. I don't need it to be a civic, but my Silverado VHO gets 19 hwy so I'd like the car to at least best a 5300lb truck with a 6.0 and 3.73s. The gas in it is a mix of what was left from September so I'm hoping as I fill up a time or two, the mpg will come up some.

NP. Even for a core that's a great price. Good luck and I hope it turns out to be in good condition internally.
