He had run consistantly in the 11.0x second range and after the auto swap and getting the tune down right he was putting out consistant 10.0x runs. The same guy tuned it with both the auto and manual setups and really the only changes in the tune were to account for the automatic stuff. Did have to change computers though since the manual computers won't run a full auto setup unfortunately. Darrin

auto tranny will always shift faster then a guy with a 5 speed no questions. thats why alot of pros use an auto tranny in drag apps.

J-Mod by ford is the only other i would use but id prefer b&m. they are the same thing different company.

[Darrin]

b&m actually doesn't do anywhere near the same thing as the j-mod.

The link that you provided above has a great price for the valve body, but I had someone buy one from him and took it apart. I was not pleased with it because the valve body was simply sprayed down and not fully disassembled and cleaned or inspected. The one I got back had a broken 3-4 capacity spring in it and the valves were all dirty.

His plates are simply overpriced in my opinion.

I offer complete valve bodies and plates, but my valve bodies are much higher priced and all I can say is that I do all of what needs to be done and you definitely get what you pay for

My plate kits are higher priced, but you get the plate, gaskets, accumulator springs (accumulator pistons also on older than 98 setups only), and a new filter. I also include some really nice instructions.

Torque converters are definitely available as well, just ask. This is what I do.

if its for a 4rw70 transmission it will work. just be sure to order a kit designed for that transmission.

[shadow5403]

it is designed for the 4R70W...just didnt know why it said it was up to 99 model year. What torque converter would be good to use?

[Darrin]

I think the reason that they say for up to 99 is simply because of the lack of proper info out there on these transmissions. Like said above, if it is for the 4R70W then you can use it.

I am calling them now to have the install instructions faxed to me to see if I can tell you if they changed the kit or not since I looked at it several years ago. Back then it was very similar to the TransGo kit that I REALLY don't like.

can somone link a torque converter for a 2000 4R70W tranny. what stall also?

[Darrin]

That is a link to the proper torque converter for that transmission.

On your car you don't honestly need a ton of stall. Stock stall on your application is spec'd between about 2250 and 2600 rpm. For a nice street setup something in the low 3000 range should be good.

i was figurin around 2400? that sound about right?

[Darrin]

You won't get into as much trouble with that B&M shift kit as you can with a few others.

I really don't like the fact that they block off the 1-2 accumulator though. That can make for some abusive part throttle shifts and isn't the right way to do it in my opinion.

Also, they have you replace the main pressure regulator valve spring. I would really love to see what the difference is on that spring to see if they used the one from the Sonnax kit for that valve. If so then thats a good mod and it would have been nice to see them include the Sonnax valve with the spring.

At least they don't have you drilling into the valve body itself on this kit or blocking off stuff elsewhere like with some others out there...

According to Ford, 2400 is right about stock stall for your car. I just went out and warmed up one of those cars here to check it and it seems to stall somewhere in the 2500rpm range. That car has a very mild tune on it and it otherwise stock. Well, until I get to it that is. LOL

Are you after a simple stock type replacement converter or a performance converter?

Darrin

[shadow5403]

street/strip performance

[Darrin]

You definitely want higher than 2400 then or you won't notice a lick of performance improvement out of it. It would really suck to spend all that money and end up with no gain from it other than durability. That is why I was suggesting something in the low 3000 range. That should be enough to notice and get you up and off the line with a little oomph.

i know nothing of this topic so it may sound stupid but, if i went with a 3000 stall, how would the car perform just boppin around town as if compared to the stock converter?

[GreenFaleen]

transgo is crap period, as for a shift kit, I had a transgo it sucked horribly so I moved to a b&M kit partnered with a tuner and I loved it, j-mod is a good kit as well, also as for a torque convter on a street strip car with bolt ons your not going to wanna go over a 2500 stall (stock stall for us is 2150 and with a stock converter you wont be able to hold rpms past 2200)3000 and your going to bog like mad off of the line in a v6. best shift kit setup IMO that I have used and will vouche for is a b&m (or j-mod is good i personally didnt own one but I have driven cars with it IMO too choppy for a DD car)) shiftkit, 2500 rpm stall converter and a tuner

[shadow5403]

i started a new thread in the drivetrain section dealing with this. I already have a tuner, and plan on puttin a tranny fluid cooler on it too. Would i need anything else besides the shift kit and the torque converter?

A lot of your info isn't absolutely correct. If you go to the Ford service manual for his year car you will clearly see that the stock stall is never that low. Usually a decent car will stall at or near the high number inthe specifications. Which, in this case, is between 2240 and 2619. The converter should never stall at 2150 or it is out of spec.



Also, a properly j-modded transmission is the absolute smoothest of the modified transmissions at low to part throttle that you can get and they bang with the best at wide open throttle. The key words there are properly j-modded. That said, I have to propose that if you have never driven one done properly and you are nearby and want to experience that then I definitely would love to invite you over to drive some cars.

There is a lot of bad info out there abotu this stuff and it woudl be great if we could all work together to start and turn that around so that we can provide the right kind of help to those that want it.
