It will be an issue LOL

 

im about to order a hayden trans cooler . do some of the chevys come with a small a small trans cooler stock ? yea looking at slicks to

 

Yes they come with a little baby 8k gvw transcooler or something real small. I run a 30k cooler inline with the stocker and the radiator.

Just so you know, and I'm speaking from experience, but your trans will be on borrowed time with that converter.

I recently lost the 3-4 clutch packs in my transmission. It had all kinds of good stuff installed: full rebuild, band, servos, shift kit, vacuum mod, sleeved input drum, beast sun shell, sprag, etc. Well when I bought all my parts, I neglected to buy a 3-4 clutch pack and what do you know that's what burnt up on me.

Just a bit of personal experience.

 

I just had a Yank SSTB 4000 installed in my 2008 5.3 ext cab 2wd. The truck will smoke the tires at will now from a dead stop which was my goal with the converter install. On the down side of things driveability has suffered somewhat, I live in hill country and when hitting a big hill you have to rev the sack off of the truck to pull the hill with the converter unlocked. Also at WOT the truck does not pull as hard on the big end as it did with the stock converter. When you get your retune done tell the tuner to take all of the pulse width modulation out of your tune so the new converter will stay locked up when you want it too. I'm seriously thinking of sending mine back to get it tightened up to around 3200.

brett what mods do you have on your truck ? if you got just bolt on's even with the 4000 stall converter you prolly only doing 3200-3400. add cam and what not will jump it up. what i was told by dave over at yank.

 

random you cant just replace the stock one with a bigger one. or is it better to just add a bigger onto it. you can use the lines of the smaller stock one right

 

I only have a tune and a Flowmaster 40 so far with 342 gears. I told Dave at yank my next upgrade would be cam and long tubes then I would be pretty much finished with no plans of FI or any other big power adders. He suggested the 4000 stall with me wanting it to hit the tires really hard. I'm going to put a 4:10 gear in it to see if it will take some of the mush away from the converter before I send it back to get it tightend up. My converter right now will brake stall to 4000 before it breaks the tires loose. To me this is too loose for the hilly terrain where I live. Dave said it should only brake stall to about 3000 but for whatever reason mine will go to 4000. I would go with a 3200 if I were you if there are any hills where you live.

 

I also added a 40k gvw tranny cooler in line with the factory cooler and the tranny hasn't gotten above 130 degrees in 40 to 50 degree weather so far.

 

i just recently had a Yank SS3600 installed in my truck. even with the stock cam it's friggin' sweet. pulls way harder than the TT3000 i originally had.

 

I would get the SS3600,trust me if you don't you will wish you did,I promise
