That transmission is a work of art!
I have a couple of questions.
What are you using for a launch control? I was brake boosting and I was cracking transmission cases (2) and I broke one input shaft (the input shaft broke on the road months after racing). I think it might have been due to the fact I was welding my gussets in and that might have been weakening the cases. I've gone away from welding cases and brake boosting and now have tried using a launch controller. Last time I ran I used the lunch controller and didn't have welded gussets and my trans held up putting 360 hp and 460 ft/lbs of torque through it. I've done the all the other regular mods to the trans, Peloquin, tighter clutch packs, eliminated accumulator servo, higher line pressure, etc.
Are all those external transmission supports you built one-off items or are they easily reproduced?
Did you build a gusset here to support the pinion too or just the one you pictured?
What year/trans does the 300M(904 spline) input shaft you use come in, is it hollow for a lock up converter, and does the clutch hub it splines into have to be machined to fi or does it slide right in?

I have since stopped racing do to my transmission being the week link. Now a days I get more enjoyment taking my turbo-van to car shows and blowing peoples minds than I do pulling and building transmissions.
I footbrake going into pre stage getting the boost and rpm up, then I bump in to stage and apply the line locks, locking-up all four wheels, then mat the throttle against the brks, let-go of line-lock button on last(or first) yellow.
I do not weld in the gusset you showed, makes the case move around and distort, and-or crack.
I know there are those who have successfully welded their cases, but I'm not taking a chance. From experience I know how much aluminum moves around when welded, especially cast aluminum.
The strengthening girdles are one off (the diff. cover and attached plate and bar). The transfer gear cover we water jet cut from 1.50 billet, and I have the cad file for that, so that could be easily duplicated. You would only have to drill, and tap the holes.
In this thread JB weld is legitimised. This is true TM genius at work. Impressive as always Warren.
The 300M input shaft was a custom piece made by a Chrysler engineer about 10 years ago. Don't know how many were made back then, but I tracked this one down in Canada.
I talked to the guy who made them (John Donato), he said he would make more if I would commit to at least 10 pieces. And yes, it is a drop-in part, non lock-up only. Direct fit into the clutch drum, but the turbine hub in the converter must be re-splined to accept the larger 904 shaft.
There are about ten people running them as far as I know.
Exceptional work as always Warren!

I once read some where that ohiorob was pulling timing on shifts but I couldn't figure how that was possible to trigger.
Almost hope something breaks and you have to raise the bar again
Yes, through the shortest distance to the hole for the shifter housing and corner bolt hole.

As always Warren, your work preceeds you, :nod:
Any chance of making the diff cover?
Guess I've been lucky, only split one case right across the diff housing, happened while brake torquing at the line, don't really know what caused it.

Not much new here, got my torque converter reconfigured (higher stall) and installed. while waiting for the converter to get done, I finally got around to fixing my sloppy front suspension. Removed the rubber bushings, and machined some aluminum replacements, with spherical and needle bearings.
Front end is aligned and car is ready to go.

Wow. That's impressive. I take it you're going to make another trip to the track soon? I'm also noticing that I may need to reread some of this thread, because last I can recall you were ultra close to the 9s with a hybrid 50 trim or some such. Now I see in your sig that you've gone 9.82. Congrats!
Just out of curiosity, why'd you stick with the stub style arms and k frame?
Was in the nines two years ago. Built a new trans last year, tested it a few times at the track, broke some trans parts sorting it out, and found out My rebuilt converter was way too tight. just got converter back and ready to test.
Hope I can finally start upping the boost.
(PS, the Laser has gone quicker than 9.82)
Was going to build a tubular K frame, but got lazy. These stockers are light, and strong, but mainly cause I did a lot of lightening on my stock K frame years ago and I don't have time this year to tackle a full tubular build. Oh, did I mention how lazy I've become?
Great to hear updates Warren, beautiful work as always! :clap:
