didn't you already post an almost identical topic on this?

Edit: why, yes you did. It's the 4th thread down the page. Just bump it instead of starting redundant threads, please.

Very few people do...that's why there's next to nothing for information about them. Besides not being able to really control the engine, the ATX tranny is a POS

Well, it's not really a POS...... it's basically the same tranny they used in the 80's Turbo Dodges.... BUT it would need to be built up for turbo use.

The '80's Turbo Dodges used basically the same trans... with a few different options.

One problem with the 3-speed ATX is the torque convertor lockup.
I understand that it won't survive turbo use for long.

Some people (so I have read) have rebuilt their 3-spd.ATX using some of the internals from the '80's Turbo Dodge transmissions. ...Such as the Input Shaft..... this will enable the use of the Daytona torque converter, which is supposed to help the car launch much better !
Doing this precludes the use of the Torque Converter lockup, however.

Moral of the story: Sure, you can turbo a 3-spd. ATX Neon, BUT it will be a LOT more WORK, than just turboing a 5-spd.MTX Neon.

The issue is the 4 speed auto. There just aren't any aftermarket parts for them. I'm curious if parts from the PT Turbo auto will work though.

True, I have heard that the 4-spd. ATX is a whole different ballgame.

It may be capable of greater economy and accelleration <--(on paper), but durability is a problem.

Is the PT Cruiser ATX the same as the one they use in the Neon ??
Because if it is, well then......

Might do sum research on this PT tranny for my turbo project, even tho i hate those damn lil things...

The POS I was reffering to was the 4 speed ATX, which is what I have. I have installed an auxilary transmission cooler and changed the fluid regularly but it can sometimes slip just a tad in 1st. I probably would have turbo'd this motor already if it was MTX

Slipping huh? Have you tries the Lucas Transmission Fix from autozone or advanced, its good for slipping or worn trannys. It is apparently well known and a couple of people have recommended it. It's only $10, so it can't hurt, my roommate put it in his 94 galant and he said his tranny doesn't act as bad as it used to when it shifts, it is an atx...I'm about to try it just for shits and giggles because it also says it can extend tranny life and has better heat control...so we will see if this stuff works or not...

Adionik · Post by **Adionik** » Mon Oct 13, 2008 3:12 am

It's not by any means bad, it only does it ever now and then if i'm light on the throttle into 2nd, but something like that tells me it would blow up if I turbo'd it.

Lucas eh? If it's anything like their fuel treatment I doubt it will do anything. I know Seafoam made an ATX solution that is supposed to do good. I have heard of some guy using a transmission fluid additive then he had a lot of problems afterwards...so until it gives me some more issue i'm reluctant to use anything (aside from changing fluid)

Lambostealth turboed his atx, it was pretty sick. But I do not believe he owns that vehicle any longer.

T-Nasty · Post by **T-Nasty** » Sat Dec 06, 2008 10:04 am

put in a valve body and an aux cooler. the IC piping is a bit more tricky with the ATX the tranny itself is alot bigger than the 5 speed. I must warn you though the ATX is a dog compared to the 5speed. the gears are alot steeper. but its been done.

Post by **occasional demons** » Sat Dec 06, 2008 11:16 am

A valve body would only apply to the 3 speed. The 4 speed doesn't have one. It has solenoid valves. Figure out a stand alone controller and you're golden. As long as you're not tyring to push over 200 ish hp... then some upgrades will definately be required. To use a crude example, the TCM cycles the solenoid valves like an injector, before full open. If you could program it to just open them that would be your "shift kit."

Adionik · Post by **Adionik** » Sat Dec 06, 2008 2:06 pm

Sheesh...if you're not hitting 200HP I don't even see how the money and effort is worth it

+1. Might as well just have an r/t with nitrous.

I wouldn't say it's impossible, but there will be challenges.

I know someone who turbo'd an NGC Neon (2003?) They eventually gave up on the car, and got an SRT-4.
The reason was that the 2003 Neon had some problems with tuning and drivability..... they would have to re-set the PCM every couple of weeks at least to "fix" it.

The PCM was doing its job..... which is to keep the engine running within parameters as much as possible, with the best possible mileage and lowest emmissions.
Throw a turbo on the engine, and now you've thrown the parameters out of whack, which will cause the PCM to *try* to "compensate".

I don't know what some of you are smoking. Mine ran excellent, and the trans held strong, I never felt even the slightest hiccup from my tranny, but, I also flushed it EVERY 20,000 miles. If someone could figure out how to increase the trans line pressure, it would shift harder, and last longer. But again, never had an issue with mine.

For reference, I was running a Hahn S16G, and the portfueler, worked excellent once I opened their map clamp and readjusted it.

I was hoping you would jump in here, too.

See people...it is possible if you do it right.

Oh and just for reference, I ran a SRT-4 turbo and then a .50 trim. E-Manage with dual secondary injectors for fuel. The way the auto rolls into boost worked very well with the E-Manage.

I have a three speed auto. best thing i did for it was replaced the steels and clutches to koleen or how ever you spell it, also I have a six disk clutch pack in my high gear as well. oh yeah, modified valves in it as well as a reverse manual valve body... stock torque converter with the lockup on a switch. weak part is the flimsy lockup plate in the stock converter. when your bangin away at it just turn off the lockup. AS LONG AS YOU HAVE A TRANS COOLER!! then when your daily driving just leave the circuit activated and the PCM locks it up for you!

sounds like a lot but i got about 500 bucks in it including the core trans...
so yes you can turbo an auto... quite well as a matter of fact.

Nice, my project is install a stage 4 AGP turbo kit on my neon 00 ATX, can my car handle it?, i have moroso trans oil cooler, driveshaft stage III axles, and the misterious valve body sales by moderperformance years ago, (i say misterious because i look too similar to the oem, i dont know what was the difference and i feel it like the stock one), can handle 500hp?

The 3-spd. ATX can be MODIFIED to handle 500 hp, but it will need more than just a shift kit and trans cooler, from what I have read.

4 speed ATX's have been taken to 10's now, RacerSteve on neons.org did it with his car. It was a stock stratus from a 01 or so, with a phatom grip differencial, some loose convertor, and a PCS controller. They work, they need to be modded just like anything else.
