Re: Hemi fourspeed overdrive
I have one in my car, and I love it. My rear is 3:54, so on the highway I can run as fast a I want without running the motor to death. Around town I usually leave it in 3rd just for cursing.

So it still has 4 gears?, the 4th being an overdrive?

How about posting it here for others to see! Seems Passon picked up where Keisler left off.

No, the Passon is completely different than any other OD trans on the market. It's not only different, it's soooo much better.

Re: Hemi fourspeed overdrive
I wish Passion was an option back when I bought the Shaft Me Keisler Perfect Fit tremec. I'm still working on getting the drive angles right. Although I now know there is no alternative other than to cut the crossmember and build a custom trans mount. BTW Silver Sport transmissions is the old Keisler and they have NOT corrected the issue with the angles- or will tell you that some of these cars, ( for some mysterious reason) will not have the right angles. You have to chop your car up to find out. Sure had the right angles with the 4 speed.

Re: Hemi fourspeed overdrive
Even with a stock 4 speed, the angles could be off, that why there were special tools, and the service manual shows how to check, and correct it. And they sold shims for the job. I wonder if the OP ever decided what to do?

Re: Hemi fourspeed overdrive
Oh sure. very few cars I've worked on didn't have the shims at the trans mount for setting the angles . Now it's much easier with digital levels it takes about 5 minutes to get the readings and figure out where the adjustments need to be made. not difficult at all, as long as there is room.
