4L60E valve body reconditioning.

[dfarr67]

Anybody really happy with a service that does a quality job with vac testing reaming/repair and updates. Found a guy and was wondering if $450 was a decent number.

That's about what a Sonnax reman costs.

I do my own for the units I build.

A Sonnax AFL Valve Kit (Reaming required), Sonnax Bore Plugs, And a TransGo TCC Regulator Valve will fix 90% of 4L60E valve bodies.
If they need more than that I throw them away.

Whats the quality of Sonnax's kits- I love Sonnax parts but have read the VB's don't measure up to there own spec. Who buy the tp HD model ?

Sonnax like any other large corporation uses cheap labor & the VB's are tested on a test stand in a pass/fail. Not vacuum tested like we do in the field.

HD is for the Overrun Clutch it stay on in D3-1st & D3-2nd to protect the forward sprag, If you're not abusing the unit.....Not a need.

My plan was to cheap out on solonoids and just replace the EPC, buddy wants ALL replaced and harness- considering the age alone I'm ok with this. Is Rostra decent not a fan of ACD these days, GM Genuine?

 

[clinebarger]

The Made in Mexico ACD solenoids are still OEM made by Borg Warner.

Rostra makes a decent harness....But not quite OEM quality.

Things get expensive fast for that harness if you try to move beyond Rostra.

Are these eps connector interchangeable?

They are not, That's the earlier design '93-'02, 2003 & up is different.

You can run a early style PC Solenoid on any 4L60E & is arguably a better Solenoid.

Installed several, Not needed until you cross over 450 pound feet of torque.
