FU$% 4l60s lol, time for 4l80 swap

Well the 4l60e gave out after 2000 miles on the new motor setup, didn't get to have fun with it really lol. Only 39k on trans with two full syn trans flushes! Second gears just slips so i've been driving around first to third style lol, pain in the ass! Picked up a 09 2500 work van 4l80e with 20k on it for 250.00. Having the trans shop do alto red eagles, overdrive blue plate specials, transgo HD-2 shift kit, carbon fiber bands, 34 element sprag, 4l85e input shaft and a mag-tech deep finned pan. Hopefully that will hold for a while? Don't know to much about transmissions though? What do you guys think?

That'll hold for a long time

not to be the bringer of bad news but how is a 2wd van trans going to fit in your 4wd truck :confused: besides that sounds good :thumb: lol
yeah my 65e only lasted 1 race (and 1500 miles) with my 408 and i blew out second geat, the 1-3 is supper fun

Dont use synthetic transmission fluid its bad news to slippery!!!!!!! Use Dexron 6 or 7 whatever the newest gm fluid is

dexron iv (the newest iirc) is a synthetic, use dex/merc or dexronIII. Ive always used dex/merc Valvoline its a dexIII equivalent. anything dexron 4+ is going to be a synthetic. as the numbers go up they are replaced so 4 and 5 no longer exist really.

its the newest GM fluid that i was using, my work use to buy it by the gallon from gm for flushes. I plan on running it 2wd drive for this season and this winter i'll finish all the 4wd install. I do know what is involved with taking it back to 4wd. Don't have a ton of money at the moment so i'll just buy the 4wd parts when the funds permit. Gonna have to get the tail housing, out put shaft, longer front drive shaft and i wanna go with the HD t-case.
