Re: Tom's 4L60E build

Amazing. This is why I didn't try it myself.
As for the water...I had the trans in the detail bay at the dealership I work at. I'm assuming a cleaner got some on it being careless.

Re: Tom's 4L60E build

Got the Band Clearance right with a Sonnax 77787-02K servo pin kit, Uses 700R4 Teflon seals for the 4th apply circuit & an O-ring to seal where the 2nd apply piston rides......

Finished up the pump, Running a Sonnax .490" Boost Valve & a 10% over Regulator Spring......

Re: Tom's 4L60E build

Next up is the 2nd & 4th Accumulators, Spacer Plate, & Valve Body....


*I blocked the 4th Accumulator by driving a .250" check ball into the 4th Clutch feed hole in the case, If you leave the Accumulator piston in the case......The Lo/Reverse Clutch will no longer receive orificed lube while in 4th gear. So I leave the piston & pin out of the case & let Accumulator Oil feed the orificed lube circuit at all times.

*The 2nd Accumulator Piston, Springs, & Housing were in excellent shape & got reused with a new piston seal.

*This in a new OE GM spacer plate for a 2003 Silverado SS.....
2nd feed.....Left factory at .073"
3rd feed.......093"
3-4 Circuit....093"
4th feed........093"
BR (Band Release).....Left factory a .086"


*Basically installed most of a TransGo SK-4L60E shift kit.....
*Did not use the 2nd Accumulator Springs as they break.
*Did not use the 4th Accumulator Spring because it's blocked.
*Did not use the Pressure Regulator Spring because I use the Sonnax 10% over one, I DID use the PR Bumper Spring though.


*****Your Accumulator Valve was stuck HARD in it's Bushing, I had a like new one with the same (DX) code, Was this thing "Thumping" into 2nd before it started slipping??

This PIN (Arrow) can be removed & allows access to the Accumulator Valve & Bushing without dropping the Valve Body.
I used the recommended 24oz TG spring (For a DX Accumulator Bushing & a Vette Servo)
****After a minimum of 500 miles, If you find the 1-2 Shift a little soft for your liking......Swap the Accumulator Spring for the next heavier weight. I'll send all the extra Accumulator Springs with the trans.

****If the 1-2 Shift is too Firm for your liking.....Remove the Spring entirely.
IF it's still too firm......You'll need to source a YZ,C,CX code Accumulator Bushing & Valve, These are found in Camaro, Firebird, & Corvette 4L60E's.
A,AX,B,BX code bushings are found in 700R4 & 4L60 units & require a slight modification to work with the "Special Pin"
I'm confident you'll be happy with the 1-2 shift after the Band gets seated in, But without being able to test drive it myself.....It's definitely a variable!

Forgot the most important page.....This gives you the Accumulator Spring colors to their respective weights.....

No, it worked perfectly until it slipped in 3rd gear accelerating on a freeway on ramp. I did put the b&m line pressure controller into its highest pressure setting at that point and drove it another month or so until I could afford a rebuild.

Re: Tom's 4L60E build

Who knows when the valve stuck, I was just curious, But I don't think it was shrapnel from the pump as I could Clear It by working the valve back & forth.....I wasn't stuck fully closed either.

Finished it up this mourning with a GM filter & pan gasket, Has new O-rings & Clips in the Cooler Fittings, New Shift Shaft Seal, And the VSS Sensor got damaged somehow.....It got replaced with a used one out of my stock with a new O-ring.

You now have 2 magnets in the pan instead of 1.
