So I have a little debate going with a few GTP owners that I can make my car perform better than theirs for less money. Their goals are 11.99's or better with $2000. My goal is fairly simple, go FASTER for less money. I currently have $675 into my setup with L/T's, ORY, Spiralflow, complete wet NOS plate kit with purge, Ls6 intake and a lid. With the budget in mind, how can I set up my trans to make it last at least for this season? I will only be spraying at the track to make the ET and then the kit will likely come off the car. I'm planning (IE: budgeting) a new/built 4L60E, but I'd like to seal this bet first.

I am purchasing a 3200 stall from a friend of mine, and the car will be wearing full slicks at the track. What should I do with the Nitrous to keep the trans alive a while? I will only be pushing about a 100 shot Digital window and keep it from spraying through the shifts? Is there a shift kit or trans tune that will keep it from grenading? I hear a trans cooler is a must, recommendations for size?

I'm a complete auto noob, all my previous performance suited vehicles have been manuals. I'm open for advice either way!

 

I ran 11.0-11.10's for three years on a stock 4l60 using the following technique. Ran 150hp through a Nitrous outlet plate

1. my window switch was set to cut nitrous at 5800 rpm, trans shifted at 6100

2. leave tranny in drive

3. good, large tranny cooler

I would also recommend non-adjustable lower control arms to eliminate threat of wheel hop. they are cheap

 

Yep, don't spray through the shift, and leave some of the TM in place.

 

If anyone ever tells you to cut nitrous through the shifts again, kick them square in the nuts.

 

You bought the worst plate on the market. Is this Peters' old kit?

 

I'd be really curious to hear why you think that.

To the OP, step up to a higher stall converter. A Yank SS3600 would get you real close to 11's with your other mods.

 

Yes..

 

Be carefull with TM and line pressure!

 

Shed some weight. 4L60's seem to last a lot longer in lighter cars. Lots of vettes going very fast with 4L60's

 

I can get a different plate for it, not really allll that worried about it. I also picked up a digital window switch today. What makes it bad?

GTPpower, I'm going to show you some LS tail lights.

 

Haha....bring it!

 

Good luck.. I had a 3600 stall and trans cooler put in along with a cam and first run on the street the trans went.. I had never had any previous problems with the trans either, so I was pretty pissed.

 

trans cooler ,deep trans pan.don't purge or launch with the NOS,with slicks you mite break some thing.short shift with the nos.how many miles on the tranny?short DR/slick will help ET.

 

you should be able to meet your goal with those mods right there. i went 11.64 with a 3200 stall / 100 shot. ls1 intake and stock manifolds. you got this.

 

no torque management here, line pressure is maxxed, shifts at 6200, spraying a 150 through the shifts... and its been going 2 years like this

 

hey

 

^ yup. Op is also asking "how to make my stock trans last"
Spraying through shifts and at same time deleting all TM and raising line pressure is more like the answer to....how to make my stock trans blow up in as little time as possible!

 

3600 converter trans cooler 700ish installed
Sticky tires 300
Nitrous kit with supporting mods 550
Tune 200

Spray it with a 150 hit..11s all day long easy. Yes, its that easy.
BTW, those are all prices if you buy **** new.

 

also, I would worry more about your rear than trans.

 

funny that mine has gone 2 years this way.... i didnt even have a cooler on it untill now. the key is not hot lapping it, and dont absolutely beat on it every chance you get. put it in d and let it shift. it will do the rest and will live plenty long...
