Help e40d not shifting properly.
Hey guys the truck will not shift out of first sometimes and out is second. But on initial start it shifts properly. I monitor the temp and when it gets close to 195 she starts to act dumb. I just got the truck out of the shop. Its had a fresh rebuild kit, new converter, new solenoid pack. I also through a cam sensor at it to no avail. So any info would be greatly appreciated.
