I thought the stock was 3.78???????


Here's the deal. I am running down the highway at 60mph at ~2100-2200 rpm. The engine is a big TQ engine and it feels like it needs to shift. I would love to run this rpm at 70mph instead of 60.

I plugged the numbers into the RBT calculator and it showed I need the 3.44. I have been trying to get a hold of RBT and have gotten no response; phone or email.

I have gotten a response from someone else which is good but I want to make sure I am doing the right thing.

The trans is out and I really want to get the car back together. Last time I had trans work done it took 8 months!
