    Well I got a sweet deal on a 4l80e so I guess I'm goin that route. I found a guy with a mild-mileage 80e that needed a 700r4 and he agreed to trade straight across! Go figure. Anyway, I found this converter and need to know what you guys think....GM 4L80E 9.5" 2800-3600 STALL TORQUE CONVERTER 4L80-E:eBay Motors (item 250549646150 end time Jan-15-10 10:05:08 PST)
    I heard that going to a 9.5" converter on a 80e makes a big difference in parasitic losses and the stall on this converter will better compliment my cam. Comments welcome.

    Also I still need to know if I need a 6.0 flexplate and spacer to run a 4l80e behind a 5.3
    thanks

    You will need a spacer and 6 hole flywheel.

    The converter looks decent but the cheapest isnt always the best. I know a similar circle D verter is about $795

    $795?! Holy piss! I know you have to pay to play but damn. This one has a one year warranty. Ill probably go with it unless someone has a good reason for me not to.

    Yeah its expensive but 80e converters usually are more expensive. Ill be getting one when I go my swap. They are billet is why they are pricy.

    @%$#!! Today I drove three hours one way to pick up what I was told was an 02 4l80e. After getting it home to look at it and doing a little research, I found out its a '96 model! Does this change anything major? I know they were changed a little throughout the years - I think 97 or 99 but I dont know if it changes if I can use it or not. Please advise!

    I knew I should have done my research BEFOREhand so I would know what I was lookin at when I got there. Then, I could have identified it right there.

    are both cooler lines next to each other or is one near the rear of the trans and the other up front?

    Thanks for the confirmation! Did your cooler lines install with no modification? Any issues with the gear linkage?
