Opinions on transmission type to use.

[TurboTerror]

Hi all. Been a while since I was here & things are progressing with my new car.
Ok... as there seems to be a good variety of racers on here i'd like some opinions on what type & brand/builder of transmission to use.

I dont want to run a Lenco or the likes as the car is street legal, so i'd like to stick with an auto type. I'd also like a 3spd but I dont know how long one would last in a 3300lb car with a twin turbo'd 615 in front of it. I'm running a 34.5 tyre also.
There are so many options over there that i'm lost. I'd like to hear preferences & why, pros & cons etc.
A couple of makes i'm considering are Abruzzi & Rossler.

Any help/options anyone?

Thanks.

Would a 4L80E survive? I have run across a guy who has one behind his Twin Turbo 468.

I'd probably go with the turbo 400 since you're wanting to stay with a 3 spd. They can be beefed up pretty good.

Thanks, Don

The pro mod 400 from TSI is as good as anyones. Both companies you have listed have the same stuff along with Coan. All of them purchase most of the aftermarket parts needed for these to survive and I could assemlbe it with my eyes closed an it will live. Ask them about a real warranty in writing and that will separte the good ones from the bad. The converter is more critical than the tranny. This application will warrent a spragless design if your over 800 lbs of torque and we know who makes those the best (TSI) if you don't know. I can help with the unit shipped right to your door. Private message me and I will shoot you over a quote if your interested.

Rossler said they'd give their TH210 a 3yr warranty which I thought is very good & there was something he mentioned about the use of a spragless convertor for the street but I cant remember exactly.

Yeah everyone who says that just proves that they did not own the patent and still believes a sgrag is the way to go. A sprag or spargless on the street, for which you might do 10 times a year or something will not affect your tranny nor performance. I run a 540 in my 68 RS, which is for sale, and run 8.50's @ 160 with 0% converter slippage with a TSI spragless. My cars runs away from the whole class once past the 1/8. If they are beside me in the 8.50 index stuff we run, they are going home. I run this on the street and is killer. The 2 speed is there just because I don't like taking trannys out. If your car was mine, I would kill the 3 speed stuff unless it is the Pro Mod style TH400. The 3 year warranty thing would have to read 5 times to understand just what is the warranty going to cover. No one does that @ 100% warranty and your going to abuse it. Thats why your building it. I will warranty a tranny for 5 years as long as no abuse happens! But, your going to abuse it so get used to fine print. I do prefer the 3 speed, but for applications like mine, the powerglide gets it done and does not break the bank. There are very good TH400s out there. Just how heavy is this car and just how fast do you want to go?

[TurboTerror]

The car will be maximum 3000lb with all the road gear in it (lights, wiring looms, glass windshield, wiper motor etc).
I had a glide in my last car & didnt really like it on the street; especially with a 6200 stall. I really want to run a 3 speed.

I'm wanting to run high 6's/low 7's on a DOT tyre & push it into the low 6's on slicks. I'm building it to bring to America for some of the streetcar shootouts so it needs to be fast judging by what's happening over there.

Cheers, Karl.

That will require the Pro Mod Style TH400 or AwesomeGlide from us. I don't do a lot of the high end TH400's, but they are the way to go if not going with a Lenco with a converter? They are the Bomb along with the JeffCo stuff. I have a blown application that is making well over 1600 hp and was @ the PRI show if anyone saw it, and it works very well. To run those times with the car as heavy as it is will require some serious power. 1800hp is usually PowerGlide and ProMod style trannies only. The Lenco or Bruno is also what I would be checking out. See you @ the shootout maybe. With fuel and cost like they are, people are falling out like flies over here. Good luck mate.

I don't like to show my ignorance but how do you know you have 0 slippage

Your Mailbox is full also.

Thanks, Underdog

My mail box is empty. I run now with just one shot (275hp), which I usually use for my second stage, 8.50 @ 160 mph and go threw the traps just under 6300 rpm. I can't really be dead on looking at the tack when running 160mph. Check the chart, it works out perfect. Even At 7.90 @ 174, I go threw just a little under 6800rpm. So when you can get a converter to do that, that is almost 1/1. It never has broke in 3 years and still on the same AwesomeGlide. This is a real street car weighing in every time @ 3300 lbs and I run 3.73 Dana 60 standard gear set rear. That is only 1040 hp with the 275 shot running the 8.50 class. 1250 hp running the 2 stages at the rear wheel. Nothing really special, it all just adds up and works very well as a package. For you to run the e.t you want, you will need around 2000 + hp. Blown or really big engine with 2 stages will be at the very least.

Rossler makes a good trans, and for the converter, hmmm there like eggs in the hen house, you may have to try a few before you get the golden egg. I would go over to the NMCADIGITAL.COM and ask some of the guys in that forum who run Pro Street, and Super Street, like Dan Millen, and Spirro Pappas, he runs a big block with a hair dryer and runs 6's. I know they can give some ideas, and you can always call Neal Chance? is that his first name???? or Lenny at Ultimate converters they have links on the NMCA site also at 203-874-2100 for Lenny at Ultimate, or join and ask someone, they will guide you to the info. I know Tim Lynch runs a glide, and some run liberty's, but another ball game there. Let us know who you talk with.

Most of the converter people out there will do a good job, but I will gauruntee they all will be spragless to use the 2000hp and not ring the sprag right out of your converter. What no one tells you about their now new sponsorship with their all new latest greatest converters that we see advertised is how many they went threw just to get them to work. I know for a fact that over 10 converters and what I was told was 16 was gone threw just to get 1 that did not slip! FACT not fiction. None of the guys will tell you nothing about their converters. Marty @ Neil Chance converters makes a nice piece and will sell you one of those bolt together units for around $2500.00. If he would make it work right the first time, you would not have to take it apart to make it right after you get it. Anyone can keep changing pumps, stators, and stall speed to finally get it right. Real converter people get it right when you order it. There is only 1 converter company that does the really high HP stuff right and don't cut both your arms off when you plunk down the ton of cash they say it takes to get one. TSI, they invented the spragless converter and it will handle well over 2500hp with less than 1 % slippage in most cases. I have used their stuff since racing and tried everyone else's stuff with finding none of them being less than 7% of converter slippage and I was blamed for giving them the rpm crossing the finish line that the unit was giving us and told every time I must be doing something to make it slip? Like I must of put the pedal to the floor and drove it to the end and that made it slip!, Yes I was guilty of that for sure. We purchased 10 high end converters from the 1 shop and all 10 were returned for a complete credit. Not a good % for that company. Most converters are fine with engines up to 1000 hp and using a sprag. This will deliever more mph and free up some hp. But when you have 1000 + and most around 1500hp, you have to run what makes less than 1 % slippage. ESPECIALLY when you have to use a lot of gear and a little tire like 28x10.5 classes. Get any one of them to gauruntee their converters or your money back and that will clear the wannabees!. TSI will do that, especially if I am building the engine.
