hey guys,
hopefully this hasn't been covered here before and isn't a naive question. I finally picked up a backup 23 spline box for my car, and right now both are bone stock but in great shape. I beat on my last box last year to the times in my sig with no real issues except sometimes a grinding on the 2-3 shift ( i think clutch adjustment and my technique were to blame there)
This year im planning to run high/mid 11's, and faster on spray. Besides clutch stuff, what tricks are out there to help the transmission live longer, shift better, etc.? I know there is only so much that can be done, and I know its only a 23 spline, but does anyone who has raced or still races these things have any tips or suggestions?
I still street drive mine so all out face plating/pro shifting is out of the picture until I am having trouble at higher rpms. Just looking for ways to get extra life or performance out of it if I can since they are both apart right now and getting back together for the beginning of my season

You can "slick-shift" prep the trans by removing the brass syncro rings and grinding every 2nd tooth off the syncro hub, as well as every 2nd tooth off the inside of the syncro slider. There were some magazine articles back in the 70s detailing how to do it. The car would become marginally streetable, you have to double-clutch when shifting to keep from "grinding" the gears. I used to race 4-speeds, and did a couple transmissions myself, it really did make them shift quicker/easier.
You dont have to remove the sync stop rings, take away every other tooth on them too, that way you dont have to double clutch.
Steel shiftforks should be used.
As long as you dont turn high rpms thats all that is needed.

There is a 307 bearing that has more balls than a standard bearing. I am curious on this topic since I have to build a tranny for my Charger...Tim
I have heard others mention these and may just end up checking them out for one of my boxes that seemed to have quite a bit of input shaft slop
They are costly though from what I have read...about 100 bucks as opposed to the Chinese bearings at 20 bucks

I have heard the recommendation of steel forks before...im assuming that they are more bend resistant than the bronze ones?
I have also heard of the different slick shift methods, although this is a street box so a full on slick shift box would definitely not work out. I have thought about the halfway, keeping the synchro rings in. Going to be shifting this thing at around 6600-6700rpms this year, so we'll just have to see how much the box likes (or hates  ) going into gear that high. Whatever I do, it needs to be able to hold up to street miles and not wear out super quickly

yup, I think one too many times...like my original post, was looking for stuff other than clutch tuning that helps. As much as I'd love to spring for an adjustable, its out of my budget, and definitely out of the realm of street driving that I do on this thing

Do nothing.
I shift a STOCK 833 to low 11's on slicks...and drive it a ton on the street. I power shift it at around 6,200rpm.
Im hoping my experience will be similar to yours...and that my increased shift rpms won't change that too much

Not to hijack this thread, but I am in a similar situation. I have 2 boxes, with 2 different shift fork setups. Either of these better than the other? First one:  Second one:

F1, I like the steel fork in the bottom, but see the other fork isn't. Try to find another steel if possible. Inside of that trans looks good.
When it comes to the side covers I would highly recommend sending them to Liberty for the HD modifications. They incorporate a knock in seal so you don't have to rely on the fork o-ring, install 3/8 studs on the linkage side as the factory 5/16 will beat back the edge quick causing linkage slop. Last couple I had done were 100-150 bucks pending on what I had them do.
Good luck.

Let me know if you can't find a fork I've got a few laying around. PM if you need.
If I get a chance I'll take a pic of the hd cover tomorrow.

Hey Andre,
if you could post a pic of that cover it would be great! What is the benefit of the steel forks? less prone to bending/breaking? Both of my transmissions are currently brass forks like in the first picture above
thanks!

My experience withe the brass fork is that the shaft will sheer off of the fork at the most inopportune time.
Getting old just means you were smarter than some and luckier than others.

Been there, done that 
Get the steel forks and cut the nubs off and use them in the early cover
