4r100 wouldent shift 2nd full throttle
Went to race a dodge the other day, it was really hot outside. Left the line around 10psi launch and got a jump on the dodge but when it came time to shift to 2nd the truck seemed like it went to neutral I let off the throttle and it shifted.
Could it be from the heat? Trans temps were at 155*. I bought the truck used and the owner before said it has a beefed up trans with a billit converter.
Can this be the valve body, or sound internal?
I got on the truck in the morning today and it shifted fine.
