My last purchase
June 15, 2019
In the past, I have been very satisfied with every aspect of my purchase. This time everything was great except the shipping time. Took 10+ days to get here. The tracking indicated it was hung up in Kansas for almost a week (yes, a holiday weekend occurred during that time, but still . . .)
Fit Perfect for my 2000 Chevy Silverado!

Worked like a champ, however be sure that the transmission fixtures are tightened. When testing I didn't check and it leaked a bit of fluid but tightening them worked nicely!
Very impressed
