Any way you could drill and tap in a roll pin and jb to secure it better?

The trans will hopefully be out this weekend and i can get to swapping everyrhing over to the other case i have

Well that's unfortunate.

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.

25$ today at the transmission parts store

A bag of bellhousing bolts
A Transmission filter
a secondary spring to put in the 1-2 accumulator

I figure while im here i'll remove my block off sleeve, and instead do a beehive spring setup.

It'll still be firm, but not so damn firm its pounding the casting to death at part throttle.

Fully blocked off, it'd bark tires and get the truck sideways at WOT 1-2 @ 6300. Kinda scary.

I did a hard pull from 1st in the rain and it blew the tires loose in 2nd and fish tailed haha. Guess thats what 4AWD is for in the transfer case.

Im not wanting to be in "full race mode" all the damn time. Like my lumina, i want street manners at part throttle... like so my wife can drive it even

Then at WOT, it needs to be scary.. when it gets a turbo i'll be aiming to have the same behaviour

 

[squaredeal91]

Yessss!!!!!^^^

Yessss!!!!!^^^

Man, it makes me miss my lumina so much. Most of it was in the turbi sizing. I used a T04e with i think a .5 a/r exhaust housing.

IT paired beautifully with that 3100.

You could drive around part throttle, stay out of boost, drive like a sane human, get around 20 something mpg. I had the trans tuned to match that profile.


Then when you laid on it, it'd smash gears, and straight up devestate some stock and slightly modded v8's.

With the manners this 4200 has, coupled with VVT, im thinking a properly sized borg S366 will pair well.... this motors pretty much "all in" by 2000-2500 if you give it the beans, but otherwise, you can float around town with part throttle under 2500 rpm

Trans and transfer case in tonight.
I guess all this weight lifting finally had a purpose, i pressed the t case off my chest into place haha

Got the truck together last night! Went to take it for a drive and its moving slow as a slug in fwd.... it immediately seemed like a 3rd gear situation, which is default for the 60e when its got no power.... i thought how in the hell? I plugged up the connector?

All these check engine lights are on for tcc solenoid, shift solenoids, force motor current, etc (trans errors)

So i drive back to the house, get back under it to find i didnt have the plug fully pushed in, i guess somehow the pass thru connector wasnt seated in the case.

So i plug it all up, get back in, and go to drive it. Shifts beautifully again. I Get back home and go to find my phone for s light so i can see if its leaking any fluid..... then i realize.... My phone! My phone! Lol I left it on the frame rail earlier!

So i got in the truck and began driving down the road with the flashers on and found it face down with the flash light still on. Man what luck. Lol

Either way, everything ended up working out, with no issues.

That's pretty incredible you found your phone not broken to pieces. I've destroyed so many lol

Related story just happened. Put my little girl in her seat in the back of my 4runner. Set soda cup on roof. Drove 5 miles, soda cup was still there haha. Roof rack kept it in place.

I remember when I was a kid me and my dad went to a hardware store over 45 miles away and when we got there and started walking away one of us noticed my dad's yellow screwdriver on the chevy step bumper lol most of it was freeway driving too
