F/I SHO trans question........

[OSU 4 SHO]

Simple question:

Anyone with a F/I ATX SHO?

Wondering if they are capable of holding the huge tq numbers if they are properly rebuilt.

I really wan't an excuse to pick up another SHO, but only if I can make it have huge hp for less the price of my first born child. I know most of the high hp supras and vettes swap out to a built auto, and was wondering if this was a choice for us as well. I know its not the ideal trans for fun, but if it will allow me to have a high hp SHO. its worth the sacrifice.

Thanks guys.

Yes, Alex has one (somedude off of here)

No they cannot handle the torque of a F/I car...

So is there any trans that has been mated to the SHO that can? SRT-4 trans, 02m GTI trans etc?

I am new to swapping transmissions, so some help in how to see if they would fit would be great. I assume you have to find shaft length, bolt pattern etc?

Right now people are working on that. But I'm not at liberty to say what exactly they are doing, it isn't my project and if they want to give details, that is all up to them.

Right now I'm running my stock tranny but am trying to be really nice to it. For the most part I granny shift it to try and make it last longer. Once in awhile when I'm racing somthing comes over me and I slam 3rd, but not often.

haha, alright man, thanks for the info.

Any tips on checking what transmissions will fit? Just the general things that need to be checked would be great.

The ATX will handle quite a bit of power. I would be willing to bet that it could handle 10psi of S/C power for a few years without a problem as long as the exhaust manifolds are heat wrapped good and you can keep you fluid temps down. That is one of my problems with my turbo ATX. I can't keep the fluid temps down.

Theres the guy you want to listen to as far as boost and ATX's go......

haha i'm the guy you go to if you want to know how to break one. but seriously its a blast. I can't imagine wanting a turbo MTX

I am decent at killing them also. lol Replaced both my ATX's in my SHOs. The second one was inteded for F/I, but I sold it before I could.

I am greedy. I don't want to throw all the money into the SHO and not have a huge HP car that I can use.

If I can't figure out a way to do it, I will just buy a B5 S4 and waste my money on that instead lol.

Furthering Alex's first post...

A factory '93-'95 AX4S unit will (obviously) not hold up to the power of a boosted SHO. However, a rebuilt AX4S, if rebuilt properly, can reliably hold up to 400 HP or more. The trick is carefully balancing all of the variables in the complex ATX equation, ranging from:

- Torque converter (stall speed, fin design, clutch material, and case composition)
- Hard parts (band, drum, and gear hardness, strength, and assembly)
- Wear materials (friction material selection and clutch pack assembly)
- Internal lubrication (increased lubrication to the front and rear planetary assemblies)
- Line pressure (increasing base/TV and selected per-shift line pressures via the EPC/EEC)
- Fluid type (largely determined by usage and friction material selection)
- Fluid temperature (optimal operating temperatures fall within 165-190F)

Once you've worked the bugs out of the factory design, your main concern should be with refining transmission behavior with a proper EEC recalibration (think TwEECer) and keeping the transmission fluid as cool and as clean as possible. If you do this, you should end up with a "boosted" unit that will provide you with many trouble-free miles of operation.

Wow, thanks for the information.

Looks like I will be doing some more research. Thanks.

I asked the guy who built my tranny if it could handle 100 shot, turbo, etc. He said: "You'll blow the motor before you blow my tranny." I'm not boosted, but who knows.

where did you have your trans rebuilt?

think he would make the same promise to me

 

[SHOMurph]

The SHO is very heavy for consistant beating on an ATX.

Now if the car only weighs 2200lbs the ATX should be ok.


I'll let you know on that one!!!

 

[SeanMc]

I dunno. But like you said, it's all about keeping it cool. You should install an a/c unit in your tranny :sun:.

 

[OSU 4 SHO]

Is the normal 3.0 or 3.8 V6 bellhousing the same as the SHO bell housing?

 

[rubydist]

The 3.8 is different, the 3.0 is either exactly the same or pretty close to exactly the same, iirc.

Remove your AC and use the condensor as a cooler. :swing:
