Best bolt on tranny

strykr · Post by **strykr** » Mon Jan 07, 2008 1:52 pm

What would the best ATX bolt on tranny be for a neon.. or at least if not bolton something nice and easy. I am alot of mechanical experience, but I dont have the time to spend on working on it for longer then a few days.

Come On People Theres Gotta Be Somebody That Can Answer This!?!

Either the 3 speed or the 4 speed depending on your needs. 3 speed for performance/durability, 4speed for prolly better fuel mileage. If you don't already have the 4 speed then you will need to get the TCM and prolly a PCM the ATX/TCM/PCM should bee the same year to avoid issues, plus you'll need a harness, so for a couple of days you would need to know your shit to pull it off.

so since i got a 3 speed already, then its not worth changing over? I thought u got more power out of 4 speeds...

2k1MotorSport · Post by **2k1MotorSport** » Mon Jan 07, 2008 11:34 pm

well the 4spd does have 'overdrive' as the where the 3spd doesn't, which would be your better gas mileage.

And the 3spd has been considered the 'bulletproof' trans. And is not as computer controlled as the 4spd (which is a good thing)

I'm my opinion.. it's not worth the hassle to change to a 4spd

If you are looking for a peppier car the manual is the way to go. Its not hard to drive.

The 4 speed auto would be a pain. You may feel like there is more power with the 4 speed because you can run more gear without affecting fuel economy.

there ya go. that's what the drag racers have been doing forever.

Add to that a shift plate for stiffer shifts.

But since he probaby doesn't know what an RMVB is...

It stands for Reverse-direction Manual Valve Body, which mens first off, you have to manually select the geas with he automatic shifter, and the reverse-direction means 1st gear is right after neutral, then 2nd, then third, which is backwards from normal.

Drag racers like it, because it's still an automatic (clutchless) which means far more consistent launches, but they still have control over *when* it shifts.

If you search the "ATX to MTX" thread in this same forum section, one of my posts has a link to an srt discussion, and one of those guys built up an RMVB auto for drag.

You can drive it on the street like that, but you will always have to shift it manually between 1st, 2nd, and 3rd.

Since you stated:

Ok, I wont correct it, but do the cheap mod for the old FWD 3speeds, that will firm up the shifts and pattern...
If you dont know what im refering to, do a search here on 3speed mods or google search it...

Whats better for a Turbo Application a 3 speed o a 4 speed?, and Automatic vs Manual?

Post by **occasional demons** » Thu Jan 10, 2008 11:01 pm

Alot of ppl say ATX since it keeps the turbo spooled longer. And the 3 speed is tougher.

Arro · Post by **Arro** » Fri Jan 11, 2008 1:55 pm

Actually it depends on what you want out of the car. In a straight line? Turbo+ATX FTW. But I would prefer an MTX if you're doing anything with turning.

look up JRM's car, he has an 00 with an SRT4 swapped engine on a stage 10 ATX tranny... yes, he said stage 10, not me... but he spent a pretty penny on that thing and got 199 hp on the dyno through the atx... I think he has an 03 engine as well, which we all know was about 15 hp less than the 04-05. Any way, if you want to bypass all of that, just buy his car for 7 grand, it is a pretty car btw with full srt4 interior as well. It's a hot little mama!

Cool my ride is 3speed, and i was thinking in changing the trany for a MTX, but im decide to not make that change, excellent

Whats means RMVB?

TN.Frank · Post by **TN.Frank** » Sat Jan 12, 2008 12:31 pm

Reverse manual valve body. Instead of park being all the way up, 1st gear is all the way up, then you pull back for 2nd, then pull back again for 3rd, then you've got Netrual and park is where 1st gear used to be. It's just easier to pull back to a gear then push forward for some people.

Not quite. It just changes where the gears are.

You can't just slap it in gear and drive though.

You don't have 4th and 5th. That extra gear you kinda feel is the torque converter locking up. That should work like normal, since you aren't changing the convertor. When you do the Valve Body it will be like this:

Shifter / Gear

P / P
R / R
N / N
D / 1st
2 / 2nd
1 / 3rd and lockup.

I don't really know, I don't like to mess around inside transmissions.

Sure it wasn't a level 10?

www.levelten.com

I can't remember what his last dyno was, but on another forum I'm on there's a guy running an automatic ford EGT with a level 10 atx in it putting down some impessive numbers. Hasn't been the most trouble free, but he puts a lot of people to shame with that car.

It's not difficult at all. Figure 1.5-2hrs with regular hand tools.
Loosen the shifter cables and disconnect the plug for the valvebody; Jack the car up, drop the tranny pan, undo the bolts for the valvebody, and then pull the valvebody out (might be the hardest part). Once that's done, install the new valvebody along w/ a new filter then re-install everything. Make sure you refill the tranny with fresh ATX+4 and check the shifter cables to make sure they're adjusted correctly. It's a little more involved than that but it's pretty much the main jist of what has to be done. Hope that helps ya.

Later

It took me and a buddy about 3.5-4 hrs to drop the old tranny and mount up the new one.

As far as "buildups" are concerned, yes.... I have heard there are no real options (yet) to get more 'performance' or durability out of the 4-spd ATX.

The link doesn't work & I don't see any thing for the neon on www.levelten.com , how much is it for an auto transmission that will work with the srt-4 engine from them , I have a 2000 neon with the swap & I want an auto transmission for it & don't want to pay $8,000.00 + for the darrell cox one ?
