Best Over driver transmission

[sprdv1]

I guessed right. Even guessing the tire size and gearing. Too tall of a tire with too tall of a gear. Add in liking to drive it hard. Failure was expected.

You MUST regear or failure will happen again and again.

A 4R70W is a good choice, but it needs to be matched with a set of 4.88 gears. Bonus, it will feel like you just got another 100HP as well. If you ignore the gearing, you will smoke the 4R70W. You will smoke any automatic.

It's to be expected Broncobowsher.
Changing the ratio in both axles is expensive and intimidating too. That's why owners try to rationalize living with it.
But it won't run right it if it not in it's torque band.

for sure on both counts...
