I had my transmission rebuild by a local shop and now it failed after only a few hundred miles but since life got in the way I took over a year to install it and the warranty expired as it sat in my garage. It feels like I lost second gear the fluid turned Purple. I remove the pan and saw what looks like clutch material at the bottom ( see attached Image). I am thinking about getting a replacement transmission and I was wondering if anyone had suggestions for replacements. I was thinking about doing a 4.8L/5.3L swap at some point however I am not sure when I will have the means to do so. The truck is a 1994 C1500 2WD TBI 5.7L/350 CID 4L60E.
