Transmission decision


V8 Beast

Recommended Posts

I have been talking to a few transmission specialists and I'm getting different answers. I may go mod crazy and change my entire setup. In doing so I need a bullet proof tranny. A few say a built 4l60e will be fine, others are saying I should start looking into a 4l80e. The 4l60e's I have been looking at can hold up to around 700hp. I drive the hell out of my car. If I have a tranny that can hold 700hp how long will it hold up for a 675hp car?? Some say its fine, others say it will break before the end of next summer. Any opinions on what I should do? I'm not worried about money, because cutting corners with the tranny just leaves room for disaster. But I also want a transmission that will not have my wife cussing me out everytime she rides in my car.

I'd say it should hold well for you especially if you're looking for roll racing. Dig racing may show that tranny an easy way to hell if you do it a lot. If money isn't a big issue you may want to go with a little stronger tranny, will leave room for more mods if nothing else. It's best to go all out now rather than do it again later.

then go 4L80E, built too take over 800!(if this is possible), i know they used too build the old 700r4 too take like 1200hp. and those where total p.o.s's.

4l60's are a nice trans.. I say build it. We have one behind a Cummins, and it holds up well. Its pretty much stock, but it still puts out some torque. We just did it too see what kind of Fuel Mileage we could get. We did break a input shaft but that was stock, and it was done during play time!!

have a 700hp 4l60e built by mickey at bowtie transmissions. Total with all the best TCI componets, TCI converter and a race front pump was about 1400 (used my racer discount at jegs to get better prices on the tranny componets and converter). Although i took the tranny out and brought it to him. Still compared to what else is out there i think i got a good deal. Also if i have any probems he is local and i can take it to him.

Good point, local is good. I'm going to stay with a 4l60e. Thanks guys. I have a few companies that I am working with now. I noticed just about all of them use the exact same parts. And the ones I am working with got great reviews on ls1tech. The warranty, and location will be the deal breaker.

As a lot of CR members would say "Rossler" FTW

 

I tuned a guy with a 383 & Rossler and it's pretty much bullet proof. N/A he does 11.0x @ 122 MPH and 150 shot around 10.4x @ 134 MPH.

 

It shifts perfect at WOT, nice and firm but not too much at PT. I think he spent around $2,500-3,000.

you say they all pretty much use the same parts but thats not true Rossler has a custom3-4 clutch pack, and many other upgrades that are not available on the open market. not to mention he will refresh the trans for 500$ plus hard parts. call Carl 330-530-5000

Have you looked into CPT?

From what I've read on camaross.com, they have great customer service, 6mo warranty and use better parts than other shops. They also offer a neat Customer Freshen Up deal in case have the tranny pulled out a few years down the road and want to have it inspected and "freshened" up while you're getting your stroker kit installed.

I am looking into these guys for my latest modifications. They won't state a definative horsepower limit, but they give a good explanation to why here:

Basically, tranny holding capacity seems to depend more on 60' times than hp is what they say.

I would be interested in what you have in the end so please keep us posted or PM me the details.

I've looked into a bunch of them. I actually broke my 3rd gear mid run, and last week I went to spin the tires, just to let the engine run a little, and lost second gear. Right now I'm leaning towards Rossler because a lot of 9 second cars are using them with no issues.
