I suspect that my 18 spline Hemi a833 is proshifted.
I don't have anything to compare it to and don't want to take it apart.

I bought this prostreet challenger as a unfinished project and it has already been through 2 hands since the conversion from a prostocker to a prostreet started.

I don't know much about the trans other than that is is a 18 spline a833, has a Hurst Super Shifter 3, and a Lakewood scattershield.

Noisy while shifting but not overly hard to shift except downshifting.

Rear is a narrowed Dana with 4.56 gears, 33in tires, and a ladder bar suspension

Engine is a 8-71 blown 440 that makes around 900hp

How can I tell if it is proshifted without disassembly?

Video of going thru the gears while parked:

We used to call em ""slick Shifted" .............. had every other tooth ground off the syncros............
was smooth like buttahhhhhhhhhhhhhhhhhhh...............

Never heard of a trans being Face Plated until googling slick shifting. The want2B racer in me would like to know more about it.
 
wasn't there a Bill Grumpy Jenkins trick 1st
on Dave Strickler's & Jenkins tuned 63 Polara
or Coronet
I seem to remember reading that somewhere

64 Polara AFX Don Strickler Bill Grumpy Jenkins tuned at Detroit Dragway.jpg


'the latter 64 Dodge Boys #603 AFX too
just before they went to Torqueflites A727, were faster

& later Dick Landy or Ronnie Sox used that trick too

IIRC The trick was to take every other tooth off the synchros,
to speed shift/power shift under full power

I believe
the term to faceplate or faceplating (not even a real word)
process the gears
was a tempering & then hardening process, to strengthen the gears
(maybe even hard chroming/plating of sorts)
it has/had nothing to do with the speed/power shifting
albeit;
may have contributed to the gears in the trans living longer
then a stock gear set

I could be wrong

carry on

Faceplanting is much more involved than that. Pretty serious ($$$) modification.
 
I think faceplate refers to what is more accurately called dog tooth gears, the actual teeth are on the gear faces.

I think liberty does it.
 
Of the trans is stock, when shifting (car moving under power) you will feel with the shifter the sycro hit before it drops in gear.
Pro shifted (and I assume face plate) you don't feel the bump of the syncro cause it isn't there.
They have to be up shifted hard and fast or they won't go in gear, and to downshift you need to double clutch.
 
3 of those "face plated trans" pictures above are mine. Here's a pic of the parts I typically use, they are made by Liberty...

The dog ring on the left welds to the gear after the gear's engagement lugs are removed, the faceplate is machined into the side of the slider on the right. There's a lot of lash between the two when engaged, but there's also a lot of lash on a pro-shifted setup. I've even removed every other gear lug and slider spline in a few transmissions, basically the purpose of all these modifications is to widen the window for engagement, which makes it easier to hit that gear's engagement window at high rpm.

That picture on the bottom left above is one of mine, it's a Saginaw 4spd that has a synchro on 1st, every other stock lug removed on 2nd, 3rd is faceplated, 4th has a synchro. I do all my own transmission modifications.

Can you give us some pros and cons of pro shift vs face played?
 
Faceplate is better than pro-shift, although both shift and drive about the same. Normal wear/tear on a pro-shift creates little burrs on the engagement lugs that can eventually cause a missed shift. Basically the slider will hang up on the burrs. The lugs are usually still good, just need to occasionally tear the transmission down for burr removal. Faceplates don't require that periodic maintenance.
