I've had my interceptor in about 2 years now(2001, 20-25%,full delay)

I've noticedthat different brands of transmission fluid seem to effect how hard the transmission shifts too. 95% of the time the interceptor shifts perfectly. maybe 4% of the time on full throttle I find myself wishing for harder upshifts, and maybe 1% of the time slowly coasting down in traffic I wish for softer downshifts.

I have come up with an idea to solve this. Haven't had tome to implement it, but I see no reason it won't work.

Install a micro switch on the throttle body that will cut power to the interceptor when the throttle is closed. This should allow you to turn the line pressure up a bit.

I had considered wiring the line pressure trim pot up to relocate it in the dash with a knob on it too.

Someone who has time on their hands could arrange a trim pot on the throttle linkage to increase line pressure proportionatly with throttle position.
