faceplated t56?
faceplated t56? hey guys ive been trying to gather info about faceplated transmissions just to see if its wat i should do in a year or so and after three hours of reading and looking around i feel like i still dont understand it well enough to deside. i understand that it get rid of the synchros but how does it make it hard to miss a shift? it doesnt make it clutchless? im really just looking for as much info as i can get ill be choosing between doin this or a th400 in lik a little over a year. id love to get the car into a 275 class. also looking for some info on a slipper clutch. if anyone has info ill appreciate it not sure exactly wat ?s to ask here
thanks

I'll be doing a faceplated trans build within couple of months and I'll post a build thread here so it would be easier for the "rowers" to understand.
First, the faceplating is only done 1-4 gears. The 5-6 would be synchronized. Some people have driven their faceplated trans on the street and said it was drivable but all I can say is "different strokes for different folks". One might consider drivable, yet another would say no way. I personally would NOT do it on a street driven vehicle.

It's just a little more tedious to drive on the street. You either shift pretty much like normal, and get a clunk each time, or you can double clutch and it'll go in with no noise. "Basically" it's just like a motorcycle transmission. I plan to drive mine on the street because I don't have a trailer. Like the previous guy said, each person is different as to what they can deal with.
Check this video out. The trans here is pro shifted (the middle gear in the picture above), not faceplated but it's the same principle when driving it. The difference being if you clunk the gears too much with a pro shifted trans, you'll be dressing the gears often when it starts to pop out of gear. The faceplated design won't pop out of gear and will last much longer before the gears need attention.

i understand a bit more now. i need to learn a bit more about transmissions in general but that did help. the car will be a racecar after i do this. does anyone sell the gears to build it yourself or can i only send the trans out (i have a guy that built my trans and helps me) ive read some people think their shifting was no faster with a faceplated trans why might this be? and not being able to miss a gear does that mean if the clutch isnt fully pushed in while racing itll still go into gear?

do you think the possible consistency with a faceplated trans can hang in a class with all autos? and as far as a slipper clutch any info there? also longevity of a faceplated trans read they last forever and also read that they might not if you cant drive it. would this be a trans id have to check the internals often or any maintenance on?

Are you thinking about the faceplated trans for racing only? If not, you should reconsider. To explain what goes on the faceplated trans is difficult but take a look at the gears below. The image is from Liberty's website. The gear on the left is normal gear and the one on the far right is the faceplated gear. The "wings" are the plates the interlock with the slider and even if they don't "hit" it, it will rotate until it "locks". When you first engage the shifter into a gear and let the clutch out, the "plates" have to "lock" or "enage" before moving. When shifting, the plates either locks or rotates until it locks so there is no "missed shift". I hope you can understand this.
I'll be doing a faceplated trans build within couple of months and I'll post a build thread here so it would be easier for the "rowers" to understand.

Is Liberty going to faceplate the gears for you?

The clutch still has to be depressed but just enough to get the load off and to the next gear.

thanks guys. and i dont think it'll make the car faster i dont think i said that. what type of adjustments wit the slipper clutch need to be made? and is mcleod thee only company that makes them?
The two adjustments you make are base pressure and counter weight. How I think it works is the base pressure is the initial clamping force that's applied as soon as you let the clutch out. Then the counter weight applies more pressure the higher the rpm. The goal is to be just on the edge of slipping the clutch in high gear. Check out the umtrdragrace.com website. They'll be able to tell you a little better how it works. I'm not sure who else makes one besides Mcleod.
A faceplated trans can be shifted faster because there is no delay while the blocker sync's up the gear and shift sleeve and then moves to center, allowing gear and shift sleeve mesh. With my faceplated T-56, I'd just kick the clutch and pull or push to the next gear. It shifted into gear every time, no delay whatsoever. It would never be as fast as an auto though.
how well would a faceplated/ proshifted t56 perform on the autocross or road course? i have an LS2 in my miata and have purchased a cheap proshifted t56... i will rebuild it if necessary, real question is how quickly can one be downshifted?

if you need a slipper clutch look up rob youngblood at advanced clutch spendy but worth it, to adjust the slipper clutch you have to set you air gap, and base spring pressures. its complicated but fun in the end when you sidestep it at 8k and dont break anything i hate send a member to another site but if you want clutch info ask these guys, its all the stock/super stock/comp guys

that is true about the road racing aspect, street driving depends on your disc and if you turn up your pressures you can do it like it was nothing,
if you guys have questions about it ill refer you to the same guy i was refered to and that's rob youngblood at advanced clutches he really helped me understand clutch technology.
