I recently purchased the sk4l60e transgo kit to fix my p1870 code on my 00 Silverado 1500. After removing the valve body I couldn't get the PWM valve (or whatever it's called) out to swap the valve per the instructions. The directions say to just tap around the valve with a hammer and screwdriver on the valve body casting and I guess it's supposed to just pop out (after removing the clip on the cap of course). The valve acts like it is stuck and for the life of me I could not get it to come out even with trying pics to work it out. Anyway I ordered a used valve body off of ebay that was listed as a "96-01" valve body in the hopes that the valve isn't stuck in it. I got it today and the valve does move easier but I noticed a difference in the valve body in comparison to my old one. One of the check ball locations is cast differently. I contacted the seller to see if they knew exactly what vehicle it came out of. The ad did list my truck as being applicable to. I'm attaching two pics to show the difference. Does anyone know if this will affect anything or will it be ok? Any help would be appreciated.





If you can see the horseshoe looking pocket for my original faces down and is flush whereas the one I just got is rotated 90 degrees and is countersunk below the face.

 

Im not claiming to know anything but maybe its an updated design to optimize fluid? it appears to be the same other than that
