I posted to this thread back in January saying my upgrade by Motorwerks in Houston was doing fine. At that point, I'd only driven it hard in a 60 mph roll-on event. In the past month, I've been to an 1/8 mile drag strip twice. It didn't make it home after Friday night's event. It was fine at the track, and for most of the way home - at highway speeds - but when I got off the highway, the transmission slipped a little, then a little more, then wouldn't pull the car at all. Then the Transmission Failure light came on. I stopped the car, restarted it and it worked for 1/2 mile, then failed again. Tried again, made it 100 yards and fail. I called a flatbed and got it to the house. Motorwerks is out of business and if there was a warranty, it's out of date. Any suggestions? Do I pull it and ship it somewhere? I read good things about FixEuro in Dallas, but they appear to be out of business.

 

Hey that's not a good story! I haven't seen any indication that fix euro is out of business. Also try southern hotrod in New Orleans. They specialize in 722.6 trannys altho not the Porsche one. Having been on the inside of this thing now I can tell ya it's not rocket science. He had told me likely 3800$ for the build plus removal/install or whatever.if they can do one they can do them all. They also have a 1 year/10000 mile warranty as well as guarantee 1000 Hp capable.

 

How did you treat the car? Did you really pound it or what? What kind of power you pushing? Bad107 putting down a lot of power through his IPT build but I'm not sure he pounds it as much as he used to. Il tell ya...IpT clams to machine the K3 drum for more clutches, but I have been looking at this drum for a month now and I absolutely do not see a way to machine this thing down because of where the lower L snap ring fits. some of the other drums, yes! I'm still working on it and have ordered another K3 drum that actually fits more in its OEM form. I'm also going to run it by some local tranny shops to get their opinion. Either way i think getting 1-2 more clutches in with some other tricks wont require a miracle either. Fixeuro actually said they couldn't machine the drum on the last guy. Makes me wonder what IPT doing. I can tell you IpT is using clutches/steels that only slightly better than OEM. They are better but not really what you would see in racing clutches. ALTO is coming out with a 722.6 performance kit to be sold through S. hotrod in next few months altho wouldn't give me any details.

 

That sucks man!! Also curious what kind of power you putting down?

 

Likely maby a solenoid on the valve body. It's probably not something major... Been dealing with mine ... Did it act the same in all gears. Could it go in any gear..

 

I found there is valve body upgrading specific for 996tt tip for 5xx only @ importperformancetrans.com , is it a good deal and plug and play?

 

I did mine there. You take it out , take the solenoids off and the conductor plate off and send it in. The hardest thing is getting the 10 mm bolt out of the electrical connector.

 

sorry that sucks!!! I never liked the shop or the mechanic that worked there at all!!! such an arrogant SOB!!!

i would send it to IPT, but you would be looking at ~$8k or so.

I have had the IPT tranny for several thousand miles now, have had several runs in mexico, 10+ 1/4 miles runs, 10 tx mile run and no issues whatsoever.

 

That's pretty good record bad has there. And he's got plenty of power in front of that tranny. I'm a fan of unconventional but capable builders and now I'm just doing it myself. In fact my seals and gasket kit showed up 10 min ago!

Certainly check the TCU codes first. It could be a simple fix.

Regarding VB....if you are going to have tranny rebuilt in future just do it all at one time. There is no need or in my opinion significant advantage to having VB done w/out the tranny build. Particularly if semi-stock power levels. You need to factor in tranny oil, gaskets, filters, and labor.

 

Is the improvement significant? Shift quicker and harder?

 

To answer a couple of questions - I haven't dyno'd it, but I'm estimating 600 to no more than 700 at the FW. I've got 3071s and 87# injectors, a Protomotive tune and Europipe exhaust. Typically, I don't push it too hard, but an 1/8 mile drag requires all it can give. I only did 2 practice runs and then got beat by a new supercharged Shelby in the first round of the event. I haven't pulled the codes, but I plan to tonight. A friend said it could have just been overheated. I'll keep my fingers crossed and post tomorrow.

 

southern hotrod and Paramount.. built tranny for 1000hp plus...Jeep Srt8

 

That will just freshen up the vb. it wears out. The pressure solenoids run on a duty cycle so they are constantly cycling..

 

going from brown top to blue top solenoids will make the shifts a bit harder/quicker, but the only real benefit would come from tuning the TCU which I am not sure can be done for the 996TT

 

There are a few that have new programs for the tcu.
