It's not good to tow a car fitted with a LT77 gearbox as per our 5 speed 7's. I think my original 7 handbook says the propshaft should be disconnected if towing more than a few miles and then stay below 30mph.
2nd gear is always slow to engage until the gearbox warms up. This is normal even with the correct fluid. (There are several threads on the forum about this)
Deb, I can't see what your mechanic could have done apart from make the pushrod longer or shorter but I'm stumped as to the benefit.
