TKX .... yay or nay?

it's a lot of money - but the biggest hesitancy is 600 lb torque limit. It would be annoying to buy it then have it put man glitter across the road course....

Other Corvette's control arms

and new battery for PF2


in other news, I'm at the maximum camber for the rear so it's not going to be easy to get another -.5 degrees

trans oil leak.edited Yeah, I get it, I can always just add lube AND the level will never get to critical... but still.editededited

driveshaft out

new seal kit

trans out

bright side is there is no oil on the inside of the bellhousing

it might be that just the tail housing gasket was leaking, and yes, it's a lot more work to do it right


so sue me.edited The other side of that story is the counter-shaft may be loosening in its bore.edited Now, I can 'just' replace the case.edited Let it go long enough and it'll destroy everything

yes.... not sure who makes them, but at least one of the rebuilders does... to me, it doesn't look terribly hard to replicate if you have a lathe and/or mill

If the case is bad, I'll probably replace it with a Super T-10 from Richmond gear. That said, I've been looking at Doug Nash 5 speed/sequential gearboxes as the future upgrade. I'd love something I can bangshift on the autocross course... that said, budget wise, I need this one to survive next year. I need wheels before I need another gear

what's fun with the Super t-10 is the roundy round guys continue to use these (and there are cast-off NASCAR ones as well) - so there are updates, better cases, better gears (and gear ratios).... all for, comparatively, not a lot of money

There may be a lot of the NASCAR A431 transmissions available after the season since they are going to a new sequential transmission next year.

for those who wonder how I end up falling down the rabbit hole.... NASCAR A431 is now a new, and exciting way this has happened....


looking.....

and what a rabbit hole... it looks like it's a very attractive alternative at its price point. Much more research required, but thank you.... I'm also looking at either Jerico or Doug Nash as well. Jerico less so because they are noisy beasts.... but still...

the tl;dr is I think the mid-plate is cracked... but I'm going to run it
so
they say you should pull the main shaft out to pull the midplate....
no, you don't


the came a gasket search.edited I'm not convinced the rebuilder made a mistake - granted, the gasket he used was leaking - but still, there's probably a crack here somewhere


more gasket fun



somewhere on here

see the dirty blank spaces? those were both sealed and clean 300 miles ago

then there was the moment Luigi was laying at my feet while I dropped a gasket sealant brush on him.... oops

replaced the bushings while I was at it


​​​​​​​
back in and leaking.... we won't talk about how it's sealed now

in other news, I can now use my laptop to program the Sniper


and in still other news

Thinking out loud.

I could replace the midplate, but if you look closely at the case, you'll see the counter-shaft bore is oblong - which means a new case too. Believe it or not, these are very popular and parts are available, new, for them... including upgrades.

I'm pretty sure my Right Stuff tempenant (or permanary?) fix will hold until winter but the writing is on the wall... so what to chose - so far these seem to be the choices.

1) Doug Nash 5 speed ($3600)
2) New Super t-10 with upgrades ($2500)
3) fix and pray ($1000)
4) TKX at $3500
5) T56 - $2500 (found one for that with all the upgrades)

1) - complaints about clunky and a pain when cold
2) - highest rating I've found is 325 ft lbs -though rumor is they can handle more....
3) cheapest - and it leaves me with a spare or sellable trans
4) they can't seem to come up with a price, but I think if I do this one, I'll spend the 'extra' and get the one rated to 900 ft. lbs (stock is 600)
5) requires replacement of my bellhousing so could be the most expensive (and could require hydraulic clutch change)..

Auto gear m22 or m23 were around 2200-2500 and good to approx 700 hp. Lots of ratios. Not sure availability or price any more.


4-16-2021 price update.
[Only registered and activated users can see links. Click Here To Register...]

In 2006 the m22 was around $1900.

AGE direct looks like $2240. That is a complete m22 with a super case.

Iíve had one close to 14 years. No issues.

M23 is their new design.

Hopefully their product is still good, but might want to check other forums.

This is a bit old, but shows a middleman price.

so a bit about P2
Great Stuff has become my go-to stuff for sealing impossible leaks... it's at it again with my trans

time to attach the console cover plate better

bracket built

installed


Paul's car is back on the road.... needs an alignment but a bit of muffling for the summer so he can enjoy it until it gets rotten weather.... and now it's safe to drive
the old wheels were held on with the wrong lug nuts so it destroyed all of them
but new wheels

need to do some altitude adjustment but they look really good

Luigi felt his advice was necessary

This had me scratching my head:

Thought that stuff is FOAM. Dropped into the chandelery to get some screws etc - there it was... Permatex Right Stuff.
Does it really go off in a minute? Would it be a suitable replacement for "blue" on the corners of my oil pan gasket on install?

If/When I get this boat sold (tomorrow?) full time on Elvira!

Cheers - Jim

sorry, this stuff
[Only registered and activated users can see links. Click Here To Register...]

it doesn't shift well at all if the rods come off

the 2nd lever was backwards (offset out, not in)


and this hints what's next...

I drove it today and had all sorts of trouble with the fender getting into the tire...since I'm playing with the springs, I'll pull them out and set the camber/castor for racing at ride height.... in other news, I may have new dual adjustable shocks coming...

centering device engaged

you knew you saw it somewhere before.... works perfect

so it's set with a good baseline

Front -2 degrees, 1/16 toe in
rear -1.1 degrees 1/32 toe inedited
editedit's a good start point, still need to balance the car on scales, but that'll happen later

drove it today.... I may have to set compression to a stiffer setting. It also can feel loose in the rear (twitchy?) to the point I checked all the mount and adjustment points to see if something came loose...


learnin' any input would be great.

Need a little more detail...

Loose [in rear]:
  1. Straight line - Instability
  2. One wheel bump
  3. Hard Braking
  4. Sloppy/slow to take a set in corner
  5. Good turn-In, then washes out
  6. and, more

These are all Problem>Solution based entries in Carroll Smith's Engineer in your Pocket

It's about $20 from A-Z and pdfs can be found online too.
I'll look up a few possible answers while you wait..

It's gonna rain here (Ida)

Cheers - Jim

*check tightness of all bolts.... also, get full instructions. the QA1 steering adjust rod - it goes to a bolt that threads into the knuckle. They provide 1 washer but don't say which side it belongs - it goes on the inside or, the opposite of the way I'll install it every first time.....

Also need to revisit the spring settings up front, back to a bit of a rub under light, right turn....

and rotated the shock adjust to 9 (out of 11)... seems to handle well, so we will see.... I have Jeep work to do next then I can focus back on this

that sounds like a rear alignment issue. when it travels up and down there is no jerky movements is there? are you using poly bushings in the trailing arms?

I read once that the poly bushings in the trailing arms actually impact the alignment since they dont compress at all during there range of travel

washer placed on the wrong side was the issue this time. Drove it yesterday and it handled fine - granted, there was no hooning but no wiggle either.

would handling improve, stay the same, or be worse if I swapped to 18x10 and 18x12 for my C3 .... right now it's 18x9.5 and 19x12

I'll take a stab at it - but this is just cursory. I found a couple of SAE articles - but not a member - so didn't download them.

I have "invested" in a square setup. The wheels are 15x10, the tires are Pirelli P-Zero (275/695/15). I specifically went to a square setup as it will (should) give neutral handle - from a wheel and tire input. All other "habits" (good or bad) will be from the chassis and suspension setup. So, my choice is made. As I have no time in the car yet, I can't comment. I expect I'll keep it square as I can move wheel/tires front to rear and get another session or two out of them. My testing plan is to get the car done and run some sessions without the body, and sort chassis and suspension (Exo-Vette). Then, add the body and aero and see what works/doesn't.

Back to your Question:

Your setup is already staggered. With bigger rear tires than front - you gain traction from the rear - great on corner exit and the rush down the straight. But, you could get loose with too much power. Your alternative retains the stagger setup, so I can imagine (guess) the handling may be similar, barring any change in ride height. I did a quick run of the wheel diameters and found little to no change in the roll center between 18 and 19 inches - note I kept the same tire width 275/45 on each run. I'll send you a copy of the excel spreadsheet I used. You can play with it and see what happens - it just one axle at a time - not a full car analysis.

I wonder if any iRacing gamers might have any inputs - so to speak? Know any?

Cheers - Jim

​Well, I did it.edited didn't buy a kit because I don't care about my floor AND the driveshaft wouldn't work anyway....edited

I got the TKX with the 2.87 first gear and .68 overdrive. that does mean I need to do something about the race RedZone lifters - but I think I have a plan - I'll call tomorrow to double check but I think I can get the rebuilt to the street spec (not the race spec which is causing my lower oil pressure at idle). While this won't be a DD it might actually be capable of driving to autox next year.

In that vein, Oct 11 is the last of the season for us, then I'll start getting it ready for Las Vegas Optima next year. Just wheels - and I think I have a pretty good idea of what I can do - C5 Z06 fronts, C6 GS rears.... thus my question about wheels and square, I can only get an 18" wheel - but I'll go ahead and step up to 200 tw tires for next year....

In that vein, I'm driving to SEMA (mostly because I can) this year, so I may try to get there a couple days early and get some track training the day before SEMA starts....

Forgestar F14

opinions? watch out for....?

I may have found a reasonable deal on take offs - 18" wheels, which means different rear tires .... but I'll probably simply buy all 4....
