This evening i took apart my 4L60e, then took the swap candidate all apart, cleaned it out, and began rebuilding.
Checked my low/rev clutch clearance and piston travel with an air gun and it came out tight like i started... so no changes were necessary. I saw some minor slippage on the steel plates between the clutches, but no burning on the clutches, presumably from when rev was "locked up" with that vette servo, and i hard headedly laid on the gas til it popped... either way i scuffed them up again, and got the lil bit of shine off.
Moving on, i didnt even open the 2nd, 3rd, or 4th clutch packs. I saw no reason, they arent "case dependant" to set the clearances and i was more than satisfied with their performance
When i say "case dependant" i mean the clearances can change between castings with machining tolerances. 2nd 3rd and 4th are their drums, so whatever.
I did however check my 2nd gear band's clearance and piston travel with an air gun, and it was satisfactory.
Im taking a gamble putting the 03 pump in a 2005 trans body. Nicks transmission didnt advise it, but didnt condemn it... the local guy i get my knowledge from said its been done and does work
Nobody said no, so here goes nothing. I looked at the lineup of the pump, and there doesnt seem to be any difference, so we'll see.
I checked my final endplay of the input shaft, and ive got about .018"
Which is close to the low end, but i believe thats about what it was with the other case, so it'll be ok.
Got the valve body on, i did have to re-adjust my 3-4 accumulator's blockoff... but got it solid again so it wont move. Should thump those guys firmly still.
Tomorrow i gotta go to the parts house and get new bell housing bolts.. for some reason 2 of the NEW bolts i had put in the bellhousing got seized and i had to drill them out lol
And my pressure switch got boogered when i removed it. I think im also going to remove the accumulator block-off i made for the 1-2, and instead just put a super stiff spring in there so it wont pound the case so hard.
Either way, within this week it should be back in the truck.
