I have just recently purchased a 5 speed auto TB48. Love the auto to bits.
Except.
It refuses to hold first gear, in 2wd/4wd high and low. Even trying to manually select it, it can sometimes just keep shifting from 1st to 2nd and back every 5-10 seconds.
It scares me to think of the wear and heat being generated in there...
I've also noticed (while being a bit of a yob) that it seems to cut power or maybe throttle input when you have your foot on the brake and accelerator at the same time...
Does anyone know if there is a workaround for these issues electronically? Or am I looking at a new valve body etc?
