Will it work and fit perfectly in my 1998 WS6 T/A?

Thanks.

 

OK, does anyone know a vendor that sells this set-up?

 

I believe gear vendors has their own website.Being mainly a street driven car, I think I'd take a look at yank for some lock up converters for a TH00.

 

I have an FLP IV now, I just know I'm going to run into trouble with over 800 RWHP when I install my 300 DP shot. My FLP was 100% rebuilt 2 months ago by FLP, and it already feels like it may be performing at less than 100%. I can't really tell.

I may go with a built Ford 9" rear end too.

I just don't want any headaches anymore.

 

if you dont want headaches, learn not to drive a race/street/strip car on the road everyday. go buy a daily driver.

 

Is it possible to have a reliable th400 with overdrive? Im thinking about converting to a m6 because I didnt think it was possible

 

I'm buying an SUV in a couple months but I still need a stronger tranny when I drive my car. What does it matter if I drive it every day or just one day per year, that power level will kill an FLP IV on the first hit, not to mention the torque hit.

 

Yes,

There's many of them riding around and working perfectly with our PCM's. I was just hoping someone can tell me the best place to go. I just e-mailed Gearvendors so I'll have some pricing and other info soon.

 

The Gear Vendors OD will handle anything you can dish out, nitrous, blower, turbo, all of the above - it doesn't matter.

Shimming the union adapter properly is critical to its survival. Set up correctly it will outlast your TH400.

 

Don't take this the wrong way, but if this car isn't going to be a daily driver why the overdrive concerns?

 

I don't have a TH400.

I want a TH400 with a Gearvendors Overdrive.

 

take it from me, dont do it. yes it can take the power but the added weight, HP loss, and price is not worth it. take a look into rossler. i think they have 700R that can take that kind of power. or if you are presistent on not trusting a 4L60/700R for a 800hp car(and i would not eather) and really need to have OD, then just use a 4L80. it would be an easyier swap then the 400/gear venders and could take that kind of power with ease. you would lose some HP and add some weight over just haveing a 400 but it would be way less then the gear venders.

 

I DO drive it all the time.

"gator's 99TA" just thought he would offer some of his great (and typical) technical advice in another thread. He doesn't understand that some people want a totally badass set-up for the street and I'll spend the money to do it. The parts are there and people do it all the time. I guess he'd just rather tell me and others to keep our high HP cars at the track and never drive them on the street.

So I want OD because my car is a daily driver. I never said it wasn't.

I ask a fuggin question about a tranny and another thread goes to ****

 

I was told that the 4L80E wasn't much stronger than a 4L60E?

I know its nowhere near the strength of a TH400, right? I'm not really concerned with the extra weight and loss of HP, considering how much I'll have. My goal is to have a setup that will last.

 

This has gone to ****? Don't know where that's coming from and I'll gladly step out of it.

 

I would look into a 200-4R if it was my car. They are proven to go into the 9's in heavy vehicles and still have overdrive. Not to mention they fit much better into an F-body than a TH400, Overdrive and 800 HP is going to be expensive


BTW I saw you posted earlier in this thread that you may go 9 inch. I would keep the 12 bolt, I believe the weak link you have in the 12 bolt is going to be your posi which will be the same weak link in your 9 inch unless you locker or spool it.

 

Sorry, you got very bad info on this. The 4L80-E has the exact same running gear from 1-3 as a TH400.

If you have any questions on the function or capabilities of a Gear Vendors or a 4L80-E, just ask me. I have both.

 

a 4L80E is a TH400 but with an OD built in. to tell you the truth, i am a GM technition at a chevy dealer here in town and we replace/rebuild 4L60E's at least 3-4 times a week. 90 percent of the time there in 4x4s that people use at our local beach or trucks that people tow with. we usually will not see camaros in there because the ones that are burning them up are modded and out of warrenty anyways (although i have already did several for freinds on the side). anyways, since the 5 years i have been working at chevy dealers, i have seen maybe less then 10 4L80s go bad for various reasons. almost all of those were 4X4s or 1 tons that were used. if money is no consern for you and could live with the added weight and hp loss, then this is the tranny for you. atleast if i was in your shoes thats what i would do. as for me, i have a daily driver TH400 that i am about to drive 30 miles over to a small town for a race in about 10 minutes

 

Can someone pm me a price of a TH400 with gearvendors OD. Im not looking for an exact cost, I just want to know ball park how much it cost for this setup.

 

Quicken.................

hey man, great Q's. i myself did my own homework and this is what i decided to go with.........

1) Neal Chance converter set up loose on the t-brake, but locks up early and is tight on the street.
2) Coan TH400 with brake and manual v-body.
3) US Gear V2OD overdrive unit with a 70% O.D. gear---$1435 vs $2400+ for G.V. unit
4) Strange C/M drive shaft
5) Moser 9"/Detroit Locker/3.70 gears/aluminum center/35 spline/3" studs

i myself thought this was more what i was looking for, and the price of the G.V. could not compete. do yourself a favor and call this guy Jim @ US Gear-800)874-3271.
very nice to deal with and hooked me up very well, marked down $200, (normally $1635). if you've got the cash, hold on to it til you check them out. my car is going in on 9/25, so if it's going to be a few weeks, i can give you my first impressions.

horsepower loss is less than 1% when not in direct mode, not in o.d., so with 800hp, you should be looking at an 8 hp loss max.....big deal..small price to pay to cruise comfortably on the highway. for example, my 3.70 gear with the 70% o.d. = 2.59 final gear ratio!!!!! nice. and by the time you remove the th400 tail shaft, and add the V2OD, i'm only gaining maybe 10 lbs., i'll have to weigh it. and it's rated at handling 1000 ft. lb. of torque, but is not hp limited from what i understand. the G.V. unit however, i did not get a torque rating, but a claimed 2000+ hp capability. for me, i will look no further than about a 1000 hp max, due to it being a convertible, and driven 5000 miles a yr roughly.

anyway, pm me with any questions you may have, and let me know what you decide to do.

thanks, and go for the 9"/locker combo, & stay away from the spool IMO.

oh yea...my old chevy mags use to offer a G.V./TH400 setup rated at 1000hp.
you can call them and ask if they still offer it if you do go with them. otherwise, expect to pay aroung $1700-trans/$1435-V2OD...have fun.
