Need Extreme Automatics 200-4R Stage 11 feedback

[dart6]

Hi
What are their manners like purely for the street and cruising with a lockup converter?
Are the line pressures extreme
Looking at putting one behind a BB Moper

I’ve got one in my GN, stage 2 with billet forward drum & David Husek 3021 L/UP converter., Hughes Deep pan with
700-R4 bottom feeder filter. Running DEX VI transmission fluid thru the radiator & external LPD external cooler.

Street driven car , works great , shifts are crisp, no issues .
Plus EA offers a $450 lifetime re-fresh

Thread 'larger boost valve'

Dec 18, 2023

I was looking around for a larger boost valve and I can only find the one from PTS which is .555 and the .500. Is there any thing in between? I believe I have heard of a .521 but I could be wrong? I can't find it.

I too run one. he offers two shift packages today. Mine came a little to form for street almost 15 years ago. One phone call and a 1/4 ball and it was perfect.
15 years and 25K miles it works perfect today. It came lock a few years later I broke sprag and went none lock and just recently went back to lock.
I always call when I make a change that walk me through and it works every time
I have always ran B&M and TCI non synthetic

The re-fresh has changed to $750. Refer to Extreme's web site.

I haven’t been on their website for the past couple of years.
Thanks for the update & for correcting me. I guess they’ve upped their pricing for this. Was $450 when I had mine done ( 2 yrs ago), makes sense on the increase though with inflation & cost increases. It’s still a great deal regardless

Are you rocking back and forth when you're changing gears?
