I have a 2000 Auto Formula that put down 451 RWHP & 402 RWTQ on MOTOR N/A on the dyno before 1st & 4th took a dump on the trans.

I really don't want to convert to a T-350 Trans. I love the 1st gear ratio in these 4L60's. I have a Yank PT4000 in the car now. The car has had over 150 pass's on this Built Trans I had done at Phoniex Transmisson about a little over 2 yrs ago. Most pass's where in the range of 6.9 to 7.20s pretty consistant, But it is now toast!

My combo is pretty simple.
Yank PT4000
TFS 215 Heads
FAST 90/90
Vinticator Cam
Stock 10 Bolt w/3.42 gears
Kooks 1 7/8th Longtube Headers in to a 3 1/2inch X-pipe dumped through Pro Twisters.

My goal on motor is
6.65 @ 102 N/A
5.99 @ 120 on 180 shot.

I am thinking about dropping down to a Yank PY3800 Extreme Billet Converter so I can spray a little more then a 150 shot. I think I could get away with a 150 shot on my PT4000. But would rather not chance it on this new trans I go with.

With that said. Can a 4L60 be built to with stand conisitant 6.70 pass's on motor & some Low 6s sec pass's on spray? I really don't want to be having to drop $2800 everytime one of these breaks & I was happy with my last 4L60, But the power I am making now makes me wonder. I want my trans to be able to go in traffic on a hot day & not worry about the converter locking up on the hwy for cruising & still drive to the track & run some Bottom 6s & maybe high 5s & be able to drive the car home.

Are there any other members who have a sick fast street car that run these 4L60s. Also open to converter idea's also. Keep in mind I want to run 6.60s on motor & bottom 6s on a 180 Shot of spray.

Thanks Seb

Seb... glad to see you on the boards doing your homework dude!

You know what I think about it. Let's go with a 60E!

And if you break it then it is not the cost of an entire unit... you know my philosophy... if it breaks we fix it for parts and labor. But, heres the deal... in racing nothing lass forever. Nothing. So all we can do is build the strongest unit we can within the budget we have to work with.

I'm in... I'll call you later this evening, say after 5:30 or so?

RPM Transmissions in Indiana has built me 2 Stage V trannys for 2 of my F/I Vettes- one 550rwhp and ran 10.60's and my current one is 603rwhp and is a low 10sec car- I've never had a problem with either one of em. Those trannys have proven to be bullet proof- there are tons 9-10sec Vettes running this tranny and have had "0" problems. Rodney (owner) stands behind what he does 100% and his customer service is unmatched, IMO. My Stage V cost me ~$2600 (shipping included) with core exchange and it took him about 4-5 days to ship to to my local installer. I'm sure ACE does gret work as well- I'm just speaking from personal experience.

Mine took 550+ spraying through the shifts for a year and a half. It was a monster weighing in at 3580.

I REALLY don't think you will run 6.65's on MOTOR, and 5.99 on a 180 shot at the weight you are currently at. It's going to take alot of weight reduction and be setup for na max effort to reach that NA...and vice versa.

Where did you get those numbers anyways? High hopes my friend,but good luck.

My motor will hopefully make over 750 with both kits on.

I will have a TH350 in the car then.

anything below 6.40s a 60e is not gonna hold up

I had one run a best of a 5.78ET @121mph and many in the high 5's & low 6's in the 1/8 mile in a 3,560 lbs w/driver, street driven 1995 Firebird with a 2000 LS1 motor & trans. It went over 300 passes, till it spit out a driveshaft at the 1,300 ft. mark. This was with lots of nitrous. So yes, it can be done and made to last.

1/8 mile track = 1/2 a race! Sorry just had to say it. In our area we only 1320 tracks so the whole 1/8 mile thing to me sounds funny. I honestly think you should be able to run 6's 1/8 mile without a problem. Vince

ive been doing it for over a year seb...and my build was half what you paid for yours

told you a while back...spraying through the shifts also...
prolly have 200 street runs and 150 track passes

A built right 4L60E can hold the power but, The question is how long. If your wanting to keep a four speed in your car why not do built 2004R I know that will hold up to your power level. It all depends on how much you want to spend, You can buy a built 4L60E but I know it wont last as long as a well built 2004R. Why not do it right the first time?(if you want to keep an overdrive if not do a TH350 or a glide)

Give us a call and we can chat about your options, One of us spons. can help you out

I didnt even know there was an option for overdrive besides the 4L60E or the 80E.

MARO-KEEN

iTrader: (10)

Yes it's a very good option we have done many swaps here at the shop with excellent results. A well built 2004R can hold a pretty good amount of power, Our stage 4 2004R is behind a couple of vipers making 850+rwhp and one running 9.50's and drives it to the track. We also have f bods running 9.90's to 10.50's that are still drivers and at 3500lbs+.

Gilbert@Ace Racing

Yeah Vince and I had a good laugh on the phone the other night once he realized many of our guys run a 1/8 mile track... we have no less than 3 nice tracks within 1 hr of anywhere in D/FW! And then of course we have the Motorplex down in Ennis... lot's of guys run there as well of course.

That peckerwood Vince told me "No wonder you **** is holding up.... your guys are only running 1/2 a race!" That was alot of fun!

And indeed there are different options for overdrives. We find that we have to work within the budgets we are handed most times... in this case we'll build a stout 60E and go from there. I tell many guys who are wanting to go very fast that anything less than our max effort Glide is a compromise, so again it boils back down to the budget allowed. Sebs unit is no different. It really does boil down to relationships and expectations.

Are the 200r4's built to be compatible with a f-body plug and computer? If so, do they run 4l60e type convertors or are they different?

Vince And Chuck at FLT helped me and my 60E do 185 Passes in a 3850lbs truck last year. Best was 6.75@105mph in the 1/8th and on to a 10.66@128 in the full 1/4. 1.50 Sixty foot. This trans was the equivilant of a Finishline level 4. Your Goals should be easy to accomplish if you get in touch with the right people. We are lucky enough to have the right people on our side.

We have a modified vss we use for speedo and all you do is take the car to your tuner and have all the flags turned off for the 4L60E. The converter is a 2004R with an extended pilot, this converter bolts to the stock flywheel.

Another vote for Rodney @ RPM Transmissions. Fragged a Rossler. Went with RPM and have never had a single problem.
