Dog-ring T56 on the street *video*
 

This isn't in a Pro-Touring car, but I thought some of you might enjoy a video of what a dog-ring T56 trans is like on the street.

This is in my recent 1967 Cougar LS swap. I got the car on the road back in June and have actually been making some changes as the summer has progressed. One of the big changes that I made was buying a dog-ring T-56 transmission. It was built my RPM and has a G-Force gear set. Gears 1-4 are face plated, while 5th and 6th gears are stock and fully synchronized.

I made a video just showing some driving around to demonstrate the shifting and the little extra gear noise. WOT shifting happens at about 6 minutes into the video. Enjoy...

Nice demonstration....

Good video!


Having the Jerico dog box in the Mustang (track only car) -- and a locker rear end etc.... There's no way I'd "ENJOY" driving this on the street. The combo of the tranny not quite going into gear sometimes (1st mostly - and this was demonstrated in the video) and the locker clunking and banging.... No thanks! On the TRACK that all goes away and it's a pure joy to drive. In the pits - it feels as though I'm "hurting" the car... it just doesn't like slow speeds... it would drive me crazy mentally. On track it's smooth as silk - unless I get lazy and miss a shift - and then it's hard to get it back into gear -- not "hard" but you need to be careful and get it right.

We know your age Weld but you just showed it there.

:mock:

This type of transmission is certainly not for everyone, which is the point of making the video. I wanted to demonstrate a few things so people have a better understanding of how it works and can make a better decision as to whether it is right for them or not.

I thought the video was priceless! An excellent demonstration.

Thank you Greg!

Andrew

Great video, you are a braver man than me to row like that with no oil pressure and completely cold. ;)

All of those analog gauges are dead besides the fuel level. All of my gauge functions are fed through the Holley digital dash mounted to my steering column.

Andrew

That actually seemed like it was quite liveable on the street. Aside from the noise anyway. I was expected a lot more harshness with normal gear changes/street driving. Did the video not show that well? What are your thoughts Andrew? Thanks for making the video.

Trey,

To me, it is perfectly streetable once you get the hang of it. In fact, I'm in the process of driving it from Oshkosh, WI to Bowling Green, KY for the Holley LSFesf.

Andrew

Thanks Andrew. That's good to hear. Have fun at LSFest.

LS Fest was a blast. Drove there 600 miles, beat on the car, drove home.

Andrew

Great video Andrew! Which technique was harder to master up-shifting or downshifting? I have a Tex T-10 that I've gone back and forth on putting in my car. My biggest concern was damaging the gear sets when downshifting. Thanks!

Just blip the throttle and bang the downshift. No worries!

Andrew

Ok I've watched it three times. Im kind of in love with the sound.

I just might be crazy?

The gear whine definitely gives the car a certain amount of character. It definitely caught a lot of attention just driving through the pits at LS Fest!

Andrew

Something to be said for that. The gear whine of an M22 in a GTO is a great high school memory of mine(this was 1999 and it was still cool)

I can tell you that I have ATTEMPTED to downshift without the clutch with my Jerico dog box.... I will never do it again. When Road racing - coming into a corner - and just "blipping" the throttle - while the clutch is still engaged - is NOT what I want on corner entry... and just jamming the lower gear - causes immediate compression.... unsettling the car.... another thing I don't want on corner entry!

I don't know if the "pros" can drive this way -- but I certainly can't!

Like Bob Bondurant once told me -- the motor is to make the car move - the transmission is a gear SELECTOR - and the Brakes slow the car down... Don't mix 'em up!

LOL

The dog boxes can and are downshifted clutchless all the time. Add that to the list of things Sutton can show you.

:action-smiley-027:

They do.

Since you're going to T Hill this weekend, watch this first:

He definitely runs the fast line through T12. Also a great example of using all the track all the time.

To clarify, I always use the clutch when downshifting. During street driving, it is rare that I have to downshift at all.
