Most of you guys on this board are making big power. I am eventually going to build a supercharged 396ci small block for my car. Anyway, I have had it with breaking transmissions. I like shifting my own gears but do not think any streetable manual will hold up behind the HP (750 + hopefully) I want to make. If there is one, let me know of it. I have been looking into the Art Carr 200 4R, and it looks like it would handle the power and since the 200 4R has less parasitic loss than most other overdrives it would be the best of both worlds. Any Ideas would be great...(I want a lenco...but the price tag makes me go into cardiac arrest)

 

oh yeah...overdrive is a must...I drive my car quite a bit and like to be able to cruise at 80mph+ without reving the hell out of it.

 

cool...how has your t5 been holding up....im getting my motor back on wednesday and i should be easily in the 400 hp range

i see u ran a 12 flat...was that with the t-5??...i am also wondering if the trans will hold up..

third gear syncro is the weak spot. it has held up alright, I had it rebuilt about 2 mos ago and 3rd gear syncro is already shot again. This is strange because I bought the tranny used (it was in a low 13 sec car before mine) and had well over 100k miles on it. I used it for about a year before anything ever went wrong with it. Now the same syncro went out in less than 2 mos? kinda strange to me. Yes the 12.0 was on the T-5, but as you can see by the MPH I was not hooking at all. I think if you ever hooked hard on this tranny, it would break.

 

If you are thinking about an Auto I would suggest a 200R4, or a TH400 with a GV OD unit. I think that a build 200R4 is cheaper than the other option. as for a stick............?????? got me. There are always JeffCo's

ive got a "built to the hilt" b&m th-350 if any one is interested...its set up for drag..and can hold a **** load of tq...

pics can be seen here

Go check out www.pro-built.net and look into his 700 and 200R4's if you want a damn strong overdrive tranny. I went through a B&M and a TCI 700R4 before I found out about probuilt. I bought it put it in and I have not had any more trouble out of my car. Dana (the guy that owns pro-built) has some guys running deep into the 10's on his overdrive trannys. The customer service can't be beaten. Dana takes alot of time with each of his customers to make sure you get what you want. Don't just take my word for it, do a search on this board, I bet you find nothing but praise about his tranny's.

 

the 200 can be built to withstand 9 second passes and 1000ft/lbs of torque, but it will cost you about $3000 for it

I wouldn't trust a 700 tranny even if *** BUILT IT for much faster than 10 seconds unless you drag race it like twice a year

WHY THE HELL IS G-O-D EDITED?

what kinda censoring is that?

 

The Tremec TKO has worked for me-so far, so good.

TKO

 

I couldn't agree more

 

bbunting, do you drag race your car at all? If so, what does it run? I could see how it would hold up road racing, but not sure about drag racing...thanks

 

IROCFAST- I haven't drag raced it yet, but I can tell you that is has survived my driving which is very abusive!

 

bbhunting, what kind of power is that making? i saw a dyno there and i though it was upper 400 range, which is still within the TKO torque specs, if he is going to make 750+hp, i assume he will be above the 500 torque rating of the TKO.

 

mine is 600 at the wheels so far

 

thanks, i was just wondering, i am going to be building mine up here over the next year (twin tubo cross your fingers for me please ) and i would like to keep it manual if i can , but was scared of spending the cash for a TKO, only to rip it to shreads because i make more than 500 ft/lbs

 

my brother has been having good luck with a 93' T-56 (car in video in sig) that has dynoed at 636 HP & 622 TQE. Drag raced & road course abuse.

 

i was thinking either the tremec t56, or the TKO. i would like a 6 speed, but would go 4 speed, if it means i won't blow it up

i think the factory t56's are actualy rated higher than the aftermarket t56, so i may need to consider that route.

 

What is the difference between the T56 in the camaro and the one in the viper that is rated at 550ftlbs? Can you make the one from the camaro's stronger?

 

the "93 only" T56 is the one with the lowest internal gear ratios and also the "weakest" of the T56's. which even with this weakness and the HP/TQ your brtoher is running is a testament to the T56's underrated strength.

 

Before you run out and drop big cash on a TKO I must let you know that the only difference between the more affordable tremec 3550 and the tremec TKO is the output shaft diameter and the input shaft diameter. since I have rarely in my time of tranny work, racing, or rodding seen either of these break off of stock trans let alone a performance piece like the tremec. I once saw a S-10 6 cyl trans input snapped off when used behind a V8 with a trans-dapt kit in a 4x4. There have been a few problems lately with the LS1 T56 now produced by tremec (since they bought B-W) in mexico. The T56's used behind the LT1 saw fewer of these problems (other than jammed/bent shift forks), which is great because these are the ones you swap behind our standard chevy engines. Most T56 problems can be remedied by the installation of a super high quality shifter like a "Pro 5.0 power tower" made just for GM T56 cars only. gear ratio mostly. If given a certain amount of area to put the gears into you put a real low set of gears like the 1st gear 2.97:1 in a T56 for 93's (P/N 10236021) one of the gears will have to be very small to achieve this ratio, therefore it has a less desirable 400 ft/lb rating (yeah right less desirable). Take that same area and put a 1st gear of 2.66:1 in it like the 94-97 cars (P/N 12558016) and the gears can both be bigger and therefore stronger to the tune of 50 ft/lb's more (450 ft/lbs). The FORD guys have been upgrading their T-5s for years by changing a few critical gears or all of them with higher nickel matrix content gears, this only helps a little but T56's come with that stock. the viper has the same exact ratios and same tranny (for the most part) as the 94-97. Why dodge says it takes 550 ft/lbs torque is beyond me, but the real questions is how come GM was under rating theirs. I hope this helps.

 

I like the T56 there is a good post on how to put one of these in your car here on the third gen homepage. I did it once a long time ago and got one of centerforces first "2 piece rear main seal to LT1 clutch" flywheels, built my own X-member, and dealt with available clutch shortcomings at the time by using a stock clutch cover and a ram 900 disc. That is what was in my JYD (picture) when I sold it (movie). I intend to use a T56 in my 91 Z drag car project with one of the Spohn tranny swap X-member/torquearm kit for T56

 

Hey Brit, I am still interested in any parts you have if you get a auto tranny. i want the 5 speed for my vert. i got a TH400 w/brake for the Bad406Z. Hey check out my car at www.Bad406Z.netfirms.com , later- steve

 

What I find interesting is that G-O-D is edited, but Hell is not I supose that is likely because of the word that typically comes After it.

I think I found the difference between the viper T56 and the camaro one...all it is, is the tailshaft.

 

there are a variety of insignificant differences between the viper and f-body trans

 

I don't know that anyone exactly knows. I've heard 2 different answers to this, one that input shaft is bigger and another that it is made of a different metal/heat treat. Either way, the viper input shaft will not match the factory T56 which will not match the aftermarket T56 (the factory f-body and vette manual tranny's used an odd bellhousing that requires an input shaft that is roughly a 1/2" longer then the standard chevy v-8 setup).

BTW, seems like when you get the car down into the 11's the T56 becomes a wear item. There's a few local guys that have gotten really good at rebuilding them and are doing it about 2x a year and they're only in the high 11's. They don't seem to 'break' as much as they just seem to wear out and get cranky like a high mileage manual tranny.

oooo, ahhh, ohhhh.....

The jerico and the g-force are just plain badass. For your information, the g-force is the tranny that was used in the recent (late '90's) LS1 Camaro that ran 9's. The Richmond is actually a very similar design (there's speculation that they are essentially the same designed by the same person. Parts do interchange), but I'd wonder about the Richmond since I've never heard of anyone happy with their 6 speed.

 

(Sorry for the slight discontinuity in my last 2 replys, I typed them around dinner time and just before I sent them I got a phone call that my brother was in a car accedent and just got back now and hit submit)

I don't know for sure that the tailhousing is different (doesn't really make a difference if they are all cast with a TA mount and just not used in other applications), but that would be insignificant anyway. The input shaft is definitly stronger on them, but like I already said, no one has really confirmed if it's size or material (I believe andris posted to another list that he was told by someone that it is bigger).
