On the snap rings for the pump bores, do they go in smooth side facing outward towards you or sharp side facing out? I’ve heard both ways. This seems correct as I pushed the valve and it moved and the snap ring stayed in place.

Hi Cline,
Do you have a wiring diagram for a 2002 external 4L80E harness and one for 2005? PRNDL wire colors and all?

These are GM "cell" diagrams, If you have trouble reading/understanding them.....I have some Mitchell full schematic diagrams, But I wouldn't know how to post them in a readable format as they're quite large.

2002 Chevy C2500HD, LQ4/4L80E......

Do you have an 04 and up also as I'm told the wires were a different color. Sold an 05 harness to someone and they are having an issue making it work with their 02 even though it's plug and play once you swap the PRNDL switch.

Hi Cline,
I see that the driveshaft manufacturers recommend these yokes with shorter barrel lengths for 4L80E applications even with the 24204289 output shaft being used. Their reasoning is that that the longer the yoke is the further away it puts the u-joint from the trans bushing, which can cause play and wear the bushing out faster. Any truth to this in an application where the Sonnax no walk bushing is installed backwards and the properly sized bearing is used to rollerize the output? What would be the draw backs of using T3-3-2431HP or U1664 yoke with shorter barrel length of 3.650" or 3.880" vs the T3-3-5571HP that has a barrel length of 5.380" when using output shaft GM 24204289 in a rollerized application? To me, the more contact the barrel has with the grooves on the output shaft, the better, no?

They probably don't realize how much spline you have on a fully splined shaft, Tell them to make the shaft the same length they would with a short barrel yoke & run a long barrel yoke.......

Will do! Thanks! I’m surprise strange doesn’t even offer a long barrel 1350 yoke like sonnax does. Sonnax tech said with the full spline shaft, you can run either their long or short so long barrel it is!
