Several years in the making.
After purchasing Factory Tech Transmissions in April of 2012, DieselSite spent the last couple years setting up the lathes and mills to cut special parts, installing blast cabinets, paint booths, and a state of the art $250,000 dynamometer powered by BlueReach Automation. They can duplicate actual driving and load conditions in a truck, including all upshifts and downshifts.

Shipping based on your location. If you need liftgate service, you will need to specify this and be aware that there is a $75.00 additional charge for this service. We will handle all the shipping arrangements getting the transmission to you in a shipping container and arrange the pick-up of your core when you are ready. So, this shipping cost is all inclusive (other than liftgate if needed) to cover shipping to you and the shipping to get the core back to us.
Core Charge. The transmission is shipped to you in a molded shipping container. We must get this case back with your transmission core. If you send back your core without the case, you will only get 1000.00 of your core fee returned. The case has a 250.00 core fee on it. If you ordered a TC and do not send your tc core back with your transmission, there will be another 100.00 deducted. ***Transmission casing can not be broke.
Custom Tuning Notes: Ask your tuner to leave the line pressures set at stock levels. Increasing line pressures electronically will only cause very harsh shifts.
Options for custom builds include:
MagHytec Deep Transmission Pan
300M Advanced Alloy Billet Input Shaft
300M Advanced Alloy Billet Intermediate Shaft
300M Advanced Alloy Billet Output Shaft
Single Sided Intermediate Clutch Pack- Designed for high rpms/ high hp drag racing applications. This is a must for Ford Lightning owners!
