Is it possible to run 9's in a m6? Can you make then stronger, can u have them rebuilt, other 6 speed trans for this car?

Well, it depends on your rear gear choice and HP as too how FAST you can go... Ohhhhh... I think you meant to ask "How quick can I go?"

Ha! Just messing with you... Yeah, there are some aftermarket T-56's built to handle at least 750 HP. I am not sure what you can do to your factory T-56 though to strengthen it - hopefully the 'experts' will chime in and provide some real help. Good luck!

Yes, it's possible, it's been done by several people (but not me... yet ). It's also possible to build up a T56, but I don't care how you build it, you can still break it. GForceTransmissions seems to have a pretty good looking unit, but it's pricey. If you learn how to build your own T56 (it's not hard, and about $300 in tools is more than enough to do it), it's a no brainer. Something goes wrong, ya fix it yourself. Have a spare T56 on hand, and you'll be fine. That's what I do.

I put my spare T-56 in yesterday and took my "good one" down to Liberty gear in Taylor, Mi to be PRO Shifted/rebuilt. I ran alot of mid 10s with 1.47 60 ft times and the only upgrade was carbonfiber blocker rings. I'm trying for a 9.99 without anything "exotic" mostly GM off the shelf parts and full interior minus backseat only. All throttle and NO bottle.

So the answer is hell yes you can build/rebuild a T-56 to be reliably fast/quick.

Good luck to ya, Tom

You'll love the pro-shifted at the track. Sux around town, but at the track, it rocks.

Nice thing about it, if you can build the trans yourself, all the parts to pro-shift only cost around $275. That's what I did.

I dropped the trans off at Liberty's this morning. I dont drive around town very much anymore, mostly track and a nice spirited drive to work on occasion. My fingers are crossed for a tailwind on a nice cool dry 9.99 kinda night. 346 cubes and she uses em all.

Thank god, to me Autos are such a turn off, no matter how fast they can be at the track.

I droped mine off at libertys a couple of weeks ago and its being faceplated, I talked to Paul and he said its just as good at the track and a little better around town. He seen the parts that came out and all of the teeth on the 2nd gear where the syncros are were broke off. I should have it back sometime this week or next then I am goign to take it back down and let him check out the clutch and see if he thinks its releasing enough. Then its off to the track and see when she'll do. I am hopeing for a 10.99 all bottle run sometime this fall.

What do you mean by Sux around town?

you have to rpm match it to down shift and i believe some people were saying that when you shift it feels like you are going to break something. Search the site. It has been posted many times. Right now i am trying to find a t56 to hold 1600 hp but it seems impossible lol. How come gforces come with the triple cones insted of being proshifted gears. I thought proshifting the tranny allowed you to shift much faster?

Camaroholic

It sucks around town because it's a pain to go up in the gears (pulling it in to second, to roll a right turn, for example, requires you to double clutch to get it in to gear - have to rev match the internals of the trans to the rear, or it won't go in to gear). And since first gear still has the little nubby teeth but no synchronizer, it flat won't go in to first gear unless the internals of the transmission are stopped.

And then it "thunks" and jolts the car pretty good if you slow-shift it. But when you're at the track, WOT shifting is awesome. Don't have to lift the gas pedal, just blip the clutch and pull the stick, slides right in to gear.

lol! maybe so but a T56 is a T56. my pocket book isn't deep enough to goto G Force, and I drive my car all over, hell went to pre- Woodward Dream cruise last night, damn traffic, hell car never went above 175, lol!

D&D Transmission did all of my work for me! Great quality and great customer service. if you do ever call them ask for Donnie Senior and tell him I recommended them

You guys are right, that would pretty much suck. I live less than 10 miles from the local track, but my car will still see 95% street driving, including some fun times on the twisities in the hill country around here. So, I think a pro-shifted tranny would be out of the question. This is the first I have heard of it and was curious. I think I am going to need to do something though, because my goal is 650 rwhp and mid-low 10s at 135-140 with street weight of around 3850 lbs. and I plan to use some ET Streets to get my 60' times down. I don't think the stock tranny internals are up to this for any length of time and reliability is very important to me.

Well, to stay somewhat on topic, what can be done to beef these bad boys up but still maintain enough street manners for auto-x and maybe roadracing?

Thanks

dont worry about it, the pro shift does not help strength.

your options are the g force trans, or just a good rebuild with the latest revision of stock parts, some viper spec, you could do a viper output shaft and possibly a cobra input shaft i think. some have had some parts cryo'd but i havent heard any great results you could contribute to that process

if you shift like crap then you are going to wear the trans parts out reguardless of how much torque you have.

also get a good off the trans torque arm

Thanks, Dave.
Do the Cobra and Viper input and output shafts have the same spline configuration as the LS1s, or do you have to change your clutch disc and driveshaft yoke? Is this really worth it and any idea on cost?

Thanks
