BTS Valve body

[Hawkins115]

So, I know that these mechanically raise line pressure to firm shifts, therefor helping your tranny stay alive...my question is, just how firm are the shifts with one of these, I'm looking for something thats firm, but not slamming, kinda like my buddy's 78 camaro auto.

Mine's not really that firm, it feels better than stock though. My tunes were burned for this valvebody, so basically my tunes I guess are running stock line pressure, or close to it.

I often wonder how the shifts will feel with the pressure raised electronically plus a valve body?

Like dave said, it firms them up, but more importantly it QUICKENS them up...

I really like the firmer shift with the valve body. There is significant improvement while towing as well.
My chip is programmed for the valve body too, and I told BTS to make it for 35's, but I only have 33's currently, so I have a slightly firmer shift than they intended, but I wouldnt change it.

The valve bodies on the 4r100/e4odcan not raise line pressure, bts or otherwise. They firm up the shift by the accumulators, like putting on heavy duty shocks. Line pressure can only be raised pressure regulator spring or computer programming. Get all 3 of these and "ouch", things start to break. A good shift should be quick, not hard.

try the sonnax tricumulator it comes with springs and a valve easy to install and only cost 50 bucks i think this will give you what your looking for

Has anybody ever used a BTS valve body or Sonnax Tricumulator with a Banks Transcommand? I have a Banks Transcommand on my truck right now and I was just wondering if anybody has ever tried this before?

BTS valve Body is very nice and not to firm. It made a good difference on mine.

The pressure plate makes the difference.
