Astro Perf.

Astro Performance Warehouse would like to introduce the "Super T-5" Gear Kit to thirdgen.org Members! The "Super T-5" Gear Kit was originally designed for Ford Mustang Enthusiasts as a additional "Option" over the Costly Expense of having to Swap out an Aftermarket 5 or 6 Speed into the Vehicle due to Higher Horsepower/Torque Ratings. The "Super T-5" was designed to be a "Drop-In" Replacement Gear Kit for all 1985-95 Ford Mustang 5.0L, and now is available for all 1988-92 Chevrolet Camaro V8 T-5 Users! The "Super T-5" Gear Kit will not work in the 1983-87 Camaro/Firebird V8 T-5 Transmissions.

The "Super T-5" has the capability of supporting up to 650HP/500 Ft. Lbs. of Torque when used with the Astro Performance 28 Spline 9310 Alloy Steel Output Shaft and Cluster Support Plate! You may have noticed we use a 28 Spline Output Shaft Upgrade over the Conventional 27 Spline used in the "World Class" T-5 Transmissions. The reason being, is that we had issues with the 27 Spline Output Shaft "Flexing" to a point where it was causing the 5th Mainshaft and Countershaft Gear to have no "Back-Lash". This was causing the 5th Countershaft Gear to "Seize". Now, granted, this problem was in a 1991 Camaro with a 383" Stroker putting 525 Ft. Lbs. of Torque Down! When the transmission was shipped back we upgraded the Output Shaft to a 28 Spline and never had any other problems. The only issue for Camaro/Firebird Users is that they have to change the Slip Yoke out on the Driveshaft. Of course not everyone is looking to apply 500 Ft. Lbs. of Torque. This is why we made the "Super T-5" Gear Kit compatible with the Factory 27 Spline Output Shaft. When you mate the "Super T-5" GearKit with the Factory/OEM Output Shaft you get a T-5 still capable of 425 Ft. Lbs. of Torque @ 550HP!

Other Advantages of the "Super T-5" Gear Kit:

1.) 26 Spline Input Shaft allows GM Camaro/Firebird User to reuse Clutch!
2.) 1st-4th Gears weigh 1 lb. 3 oz. more than Factory 1st-4th Gears!
3.) Works with Factory Bearings/Synchronizer Rings/Sliders/Etc!
4.) .79% "Road Race" 5th/Overdrive Gear Kit available upon Request!
5.) 2.95 1st, 1.95 2nd, 1.36 3rd, 1.00 4th!

The "Super T-5" Gear Kit can be purchased separately for the Do-It-Yourself Novice, or purchased as a complete built Transmission. If the customer opts to choose having us build a Transmission, the customer will be required to Exchange in a Core. CORE EXCHANGE IS MANDATORY FOR EVERY T-5 WE BUILD UTILIZING OUR OWN CORES! If the customer does not want to Exchange a Core in or does not have one, we have capability of building a Brand New T-5 for an additional cost.

wallyZ/28

how much for just the gears?

86Z

i dunno but that amount for that kit is comparable to swapping in a t56 or a tremec tko-600 id rather use a tremec then put a gear kit in my T5 and assume it holds the torque rating.

wallyZ/28

true.i know i can get a cluster and 3rd gear for my t5 for 220. but it's only a matter of time before i blow 3rd out again.lol....i was thinking about going the tko 600 or 500 route also.t56 i've seem too many problems with,but they do for what they are

Dyno Don

Sounds like G-force has found a new way to market their "stuff" , even looks like it.

dyrt

i have never seen a post with so many "quoted".....uh...."words".....

Astro Perf.

Dyno Don,

Not G-Force Products. If you look at the 1st Gear you'll notice the thickness between it and the G-Force is completely different. Plus, the 3rd/4th Drive Gears are on Super T-5 Cluster are seperate from one another, whereas the G-Force Cluster has 3rd/4th is integral. So to clear it up, these are in no way G-Force Gears. The only thing the Super T-5 and G-Force T-5 Gear Kit have in common is they both are "drop-in" replacement gear kits for t-5 world class 5 speeds.

dyrt,
In general I quote words based on terminology that helps in making it clearer to customer what I am trying to say.

Thanks,
Tony

Is that torque and HP rating with a hi-po clutch and sticky drag tires at the track, or with a stock clutch and street tires on a dyno? That seems like an awful lot of power applied to a transmission where the known weak link is the flex and distortion of the case first, and the main drive and cluster second.

Thats what I was thinking too...lol....its easy to claim a safe rating with stock tires and/or clutch, but start adding slicks and high performance clutch's and suddenly crap starts flying.

And like someone else said, at the prices here, i'd just go for the T56 6 speed.

If you believe it will hold behind 650HP and slicks, I've got a bridge to sell ya.

T56 all the way.

Astro Perf.

Kevin91Z, hgffrank,vindeezl,

The reason for the Case Distortion is due to the High Helix Angles found on the Factory/OEM Gears. When you reduce the Helix Angle of each gear (1st-4th) you reduce the Tangenical Force (Side Thrust/Force) being exerted on the Rear of the Case. We use anything from a 11 - 16 Degree Helix Angle on the 1st-4th Gears which reduce the Side Thrust by 50% over the Factory Gear Kit. Besides reducing the Helix Angle on the Gear Kit, we developed a Cluster Support Plate. This Plate replaces the Stamped Steel Plate that holds the Rear Countershaft Race and Shims in the T-5. This Case eliminates the chance for the Area in between the Countershaft and Mainshaft Bearing Journal Holes from Spreading/Cracking under high load.
So to answer your question on Torque/Horsepower, yes a Drag Radial and/or Slick can be used with the Super T-5. We run Mcleod 800 & 500 Series Single Disc Clutches, which feature both Bronze and Kevlar Material.
Please keep in mind, we don't like rating the Transmissions based on Horsepower. Torque is what breaks transmissions. We rate the Transmissions on Torque Levels achieved via Transmission Dyno and Vehicles Super T-5 Transmissions have been installed into. The Torque Rating is based at the Flywheel and in a 3,400 Lb. Vehicle.

The T-56 has potential of being one of the strongest Manual Street/Strip Transmissions. What we are trying to convey is that there is an alternative or easier solution for those making up to 525 Torque @ Flywheel. Above that the customer needs to look at something different.

its great your trying to explain everything to us but the part you seem to be missing is that we arent interested in spending the kind of money you want for this when we can have better for about the same, maybe a hair more. I think if your prices were more reasonable then interest would be higher. You are trying to get top dollar for a product that remains inferior to other transmission options.

Orr89RocZ

its always a great option for those who have T5 equipped vehicles that have done big motor builds and dont wanna convert to a T56, since a T56 isnt a direct bolt in, there is alot of little stuff that is needed to convert it over. Plus, T56's can be hard to find at reasonable prices. If you could find one for cheap with low miles on it, then go T56 if you dont mind converting over to that trans.... but if your someone like me that has aftermarket torque arm and crossmember for 700r4/T5's, and dont wanna swap that out, then a T5 build kit seems like a great alternative. the price aint bad at all if your in that kind of boat.

The only real advantage i see is that the T56 is a 6 speed vs a T5 5 speed. that 6 spd could have a much deeper overdrive which makes big gears like 4.11's much more tame on the street. it depends on the 5th gear ratio that they would offer. it be wise to offer a very low numerically numbered 5th gear to maintain great highway manners

KrisW

I think it's ideal for guys like me. V6 guys who pound the crap out of their cars and are going to upgrade but not likely to break 500 ft-lbs.

I looked at doing a Tremec TKO swap first, but for the price I would also have to change over a bunch of stuff which drives the cost way up.

I didn't buy this tranny. Mine is a custom/g-force/hybrid/world class but I have much of the same type of stuff in it. It is a drop in swap with a different clutch plate.

My next V8 car, I don't know. I guess I'll see how far I can push the one I have and then let you know.

my stock trans did fine till i hit third gear.......thats the only time i break anything ..........i may get a good kit to upgrade it.but as of now i will be putting my turbo 350 back in til i can get the funds to rebuild another t5......and i would rather put something that bolts right up to my aftermarket torque arm and trans crossmember than have to buy more stuff.........so the t56 and tremec tko's are out of the question.

MurcoRS

After looking at a TKO or T-56 swap and the cost to do the additional mods needed to use them this seems like a much better alternative to me. My car is strictly a street car and will never put out more than 450 lb ft of torque so a bolt in trans that uses all my current mounts, bellhousing, Hurst shifter, and looks factory - sounds like a winner to me! Heck, they are even in Florida so I can visit their facility and give you guys a first-hand report!

z28freak84

this is an excellent set up for those us with T5's and aftermarket parts. I already have a B&M shifter and Centerforce clutch. Next year I will probably buy a kit if I can come up with the money.
I wont even have to drop the bellhousing. It will be a 2 hour swap, instead of the ENTIRE weekend or possibly 2 if I were to install a TKO or T56. And no cutting of the floorboard, no new crossmembers.


I know you guys can do this, The price needs to come down at least $200.
The gear kit should cost no more than $795. If I could get one for $695, I would buy one in the spring after the motor is done.

wallyZ/28

i agree the price should be lower on just the gears.....they quoted me about 1100 on the gears..........kinda steep........but i am changing out my t5 for a turbo 350 for now.......it only cost me 15 bucks to repair the turbo 350 compared to 200 to 500 on the t5 patch job i'll be doing.lol

88 350 tpi formula

wow you guys need to lay off.... I really don't like the 6-speed (t-56) It's heavy ,large and requires extra work to make it fit. (gone through this twice now only did it again since the ls1 and it is pretty much choice less in the trans dept.) finding the gears takes some getting used to (hardly good for very fast shifting)

the t-5 is great! super light one of the lowest hp/tq loss to turn it. and uses cable or electric speedo out puts!!!!! with out a tail housing change or converter box.. which brings up another good point the t56 needs some good thought here if you are running a none pcm controlled car or speedo you need a cable converter box or signal changing box


the tko really is the best of both however you are not going to buy one very often for 1100.00 or so

LG4TA

I am still using the stock Mechanical Clutch Z-bar so that sounds like a great buy for me. I don't want to modify anything. I don't want to make more holes in the floor, don't want to change shifters and such and plus I don't think my 305 will break it. The 7.5 rearend might go first then.

Dyno Don

Yeah, it all sounds great until you spend the money and it breaks.
Will they warranty it...hell no!
So then, where does that leave you?
G-force made the same claims about power and torgue, and several folks broke them with less P & T. What then? More out of pocket expense.
Just bite the bullit and get the T-56 like I did ...end of problems.

I could continue going, but frankly I don't have much time on my hands. I'm not here to say our unit is better than a 6 Speed. I'm here to offer an Option to Ford & GM Consumers that want a beefed up 5 Speed without the extra modification a 6 Speed Requires. We manufacture our Gear Kits in the U.S.A. for quality. Not Price.

I would sincerely appreciate you taking your negativity elsewhere. It's not good slandering a company that supports the website your affiliated with. Especially given the fact you have never dealt with our company.

I went to the site and was looking for these parts and such to kinda start making a list. Was conciderin this for the resto Im starting this weekend. I can find anything T5 on there. Maybe Im blind or havent you updated the web site yet?

wallyZ/28

i'm sorry but t56's aren't bullitproof............i friend of mine has spent well over 2500 on his t56 upgrade and it still broke.and the company that built it said it will handle 700 ft lb.he is only producing 500 and now he is stuck with a broke tranny.
----------
i sent them an email and they responded to me..........i would rather keep the t5 in my car,but my funds are extremely tight so i will be doing an auto swap for now.
