Thanks!

 

I received my ATSG 4L60E Repair/Rebuild manual.  Pretty much read the whole thing.  I am convinced I have a chance of completing it myself as it is pretty thorough.  I should get a rebuild video next week.  After I watch that I will have a good enough idea of the level of complexity to determine if I want to attempt or not.

 

Parts are reasonably cheap if you don't mind doing the labor.  I figure I'll spend around $500-$600 on parts including some upgrades and a week off work to do it if I decide to forge ahead.

 

BTW- Manual was $20.  Can get through JCWhitney or http://atsgmiami.com/

Just watched the rebuild video (got it from KDSPerformance).

 

After watching it, I am definitely going to try it myself.  For me it's not so much the $$ as I actually enjoy taking stuff apart.  I have always been timid about trannies but after watching this I'm gonna crack into it.  Plan on getting all beefed up parts for end of Jan and take a few days off in Feb to rebuild.

 

See if I have the same opinion after finishing it
