PCS push button shifter - is it fast?

[Steve Chryssos]

I installed the Sonnax heavy duty 2-3 shift valve, that enables the overrun clutch in 1-2-3, vs. only in 3rd. This is nice, but it's a pain to have to physically shift from OD to D to enable the braking feature (then shift back), especially when you're driving on the road. What about only utilizing the D to OD motion of the push button - somehow integrating that into the paddles, then solenoid shift from there?



That would be pretty cool. And not all that impossible to achieve when the pushbutton shifter becomes available. However, during performance driving, I never use overdrive, I put it in 3rd and get on with it. As far as I'm concerned, redline in 3rd gear is top speed.

I've seen some of your other posts - how can a different converter help with engine braking? I'm interested in tweaking my transmission.
By tuning the converter different than everyone.
Also, has anybody come up with a way to engine brake with an 80? Like I said I have the 60, but I think it has a Corvette sprag in it (Phoenix Trans), so it shifts kind of firm, even with shifts set all the way soft with the Compushift. I was thinking of putting a bone stock 80 in it.

Goodness, I would NEVER give up a Phoenix built trans for a stock '80. Phoenix makes a great transmission. Please give me a call and we'll set up an appointment to go through your tune. You get free lifetime Teach and Tune as a Twist customer. As for engine braking bits, no. There's a lot of vaporware products out being talked up, but nothing tangible. Nothing drives me crazier than vaporware....
