Tranny is done what to do?

[custm2500]

The trannny in my 2001 gmc 2500 is now just a boat anker. I can get it rebuilt for $500 with a new TC. Is there a better tranny to put in the truck that will bolt up to my 6.0 and perform better for quarter mile racing? Also if I have mine rebuilt is there any perofomance stuff to do inside the trans? I know a new TC would be great but I don't want to spend a grand on the converter alone!!!!!!!! Thanks for your ideas.

500 with a new convertor? thats hell of a deal...heck convertors up here run 400+ for a decent one...also if you change specs for your convertor may need to adjust comp though not shure on that...
hell 500 is good deal..jump on it if buddy knows what hes doin...just payed 2k for tranny rebuild in my 97 :O(

yea check out wildhorsstable.com. The guy built the trannies for that truck. He has a shop and has done a probe tanny for me before. Great guy knows what he is doing and does it quick! I want to increas performance as much as posible though! Then price goes up as always!

FLt Level 4 4L80E with a 3200rpm stall. You'll never have to buy another tranny again.

What is FLt Level 4? Pauly was saying a higher stall than that. This is a truck that isn't driven much so perf all the way minuse big cost! I know it is hard but I am giving it my all!

Then a 3600 stall would be more your speed, especially if you're putting a fairly large cam. Finish Line Transmission makes a great tranny, that's the FLT part. Level 4 or Level 5 are different strength builds depending on your expected power level. Check out their website to learn a little more. If you don't plan on making any crazy power though, a rebuild on your 80E and a Yank stall converter would most likely be sufficient.

Sounds good thanks for the info. I talked to the tranny guy and says it actualy sounds electrical because I have reverse great but forward doesn't want to go into gear and when it does it doesn't fully engage and slips till it wants to go into gear. What fuses have anything to do with the tranny? He said try fuses first and then scan it if none are blown.

The trans needs rebuilt eventualy because it slips some between 1 and 2 shift, unless what has went compleatly wrong was causing that too.

Looking at either level three, or stock rebuild. Stall will be 2500 ish because I am running nitrous. I don't want to go stock because that is no fun, but for the amount of power and the minimal use my tranny guy feels it will be more than enough. Tax money get here in a few days and the it will be decision time.

Well she is at the tranny shop as I type. 2500 stall, level 4 style build. Should be back in before the end of the week.
