Blown-The carquest p/n is 2-1153 and it says "supplied to carquest by neapco" on the box. Hope that helps.

 

Did you have your d/s shortened? If so, how much?

 

the stock d/s worked just fine! the 60 and 80 are almost the same exact overall length.

 

Good to hear.
If my stall gets in by this weekend. I should have the 4L80 in by Sunday!
I think I have everything I need.

 

Do you need to get all of the tranny lines? It looks like all 80's came from the factory with a cooler. I don't have one, so will I need to get one, or can I mount an aftermarket cooler in front where the stock one would be?

 

I would recommend you get one. It'll be easy in my situation since the motor's out anyways + I think its worth the extra insurance IMO.I am not even using the stock trans cooler, but I will be pmounting the cooler in front of the radiator.
I got one of the biggest ones B&M has to offer from Allen. I'm also not purchasing new lines...I'm gonna bend my own.

 

My stock driveshaft fit,I used a TH400 yoke with a special u-joint to adapt the different size ends.

 

Guys, another question--what is the difference between the 2wd and 4wd cases for hte 4L80E? Would it be possible to convert a 4wd tranny to work in a 2wd truck? What parts and how expensive would they be?

 

Where do you get a flywheel?

 

Try 750 for that driveshaft ... Dennys wont make the N20 driveshaft in our lenght. You need a HD aluminum....
