I have a 90 F250 with an E4OD behind a 460 engine.
I have had some converter shudder so I am installing a billet Torque converter, a transgo shift kit and a larger external tranny cooler.

I have a couple questions:
1. Does anyone have any tips on the installation of the transgo shift kit?
2. How large of a cooler should I buy? I tow a 7000 lb trailer periodically.
3. Should I use any anti-shudder additives in the transmission.
4. What is the preferred tranny fluid?
4. I noticed that the transfer case bolts had lock-tite on the bolts. Should I use it also?

Thanks for your help!

on the transgo kit, just be very careful and clean. Mark things as you take them out. Their tech support is very good.
