Im looking at the 2 shift kits that transgo offers. The first one is just their diesel shift improver. They say that it is designed for a stock truck. The other one I am looking at is their heavy duty one. It is designed for racing or heavy pulling. I don't do too much pulling but do race the truck now and then. I would like a good firm shift around town but not hard enough to snap your neck at every shift. Any one have any experience with either?
The heavy duty kit- TFOD-HD2
The regular kit- TFOD DIESEL
