Z Brothers!

I finally installed the APS TT on my 2004 5AT roadster, but now I have the problems that I can drive the car on full auto, It doesn’t want to changes gears in full AUTO at WOT. Does any one has fix this PROBLEM itions with F/I . I know that this question has been asked before, but I am looking for updated info on the subject. Thank you in advance for any suggestions.

Did you have your rev limiter raised ? The AT5 shifts slow , Most get the basic flash to raise rev , and speed limits . Mine shifts right at 6800rpm and if I didnt have it raised it would have hit the rev limiter before it shifts .

 

As "booger" has stated, get the ECU "Limited Flash" and the problem goes away.

 

who sales the limited flash

 

No, where I can send it for the basic flash?

Thx bro
Cesar

 

cant you get a valve body job to help shift faster?

 

I did it on my car (Stillen), but I still have the problem.

It seems the tranny mods do not help this even thought they say it will, a guy down here in our club with an ATI SC has done the mods and gone back and forth with Level 10 with no success other than excuse after excuse, I drove it an it was really annoying hitting the limiter, I will have to tell him abut the flash fix that would be simple.

 

Cesar...good to hear the APS tt has been installed. Good luck with the tranny shifting....I am sure there is a solution for you somewhere on the boards.

 

I agree, I have both VD & TC done and I still have the problem.

Thanks!

Hello Brother

Nice to hear from you, the car is awesome! I am in love again with my car . I just need to take care of this 5AT (WOT) and I will be a happy camper. I wish the F/I companies spent more time with 5AT vehicles it is also market out there. For now I will continue using the manual mode for aggressing driving.

Blessings!
Cesar

 

check 350zmotoring.com

I read a thread a couple months back that talked about a vacuum effect & how it effects the computer that controls the a/t shifting.

hope you can find it & it helps

 

The only way at this point to solve this issue is to raise the rev limiter with an ECU reflash. A TC or VB will not make a difference. The VB makes the mechanical shifts faster and firmer, but it doesn't control the shift response from the electrical system as it relates to the rpms. Until someone can modify the TCM to adjust shift points, the ECU rev limiter reflash is the only solution in Auto mode.

 

Hey Cesaro I'm glad to here you got the car back.I hope your enjoying it.Good luck with the tranny issue.I guess we will meet up at another Z meet or fest.

Cesar,

You know what it is? It is your frictions starting to melt. We've had the same problem with our #1 tranny. Very soon you're going to see SES light with Tranny overheating code.

I'm sorry to break it to you like that, but we went through the same crap twice. Our frictions are not designed for TT torque levels. From my research your options are:

1. 6MT swap
2. T400 4-speed drag tranny (8k+install+standalone)
3. New(used) 5AT with VB+TC+big azz cooler and raised limit flash. You'll definately have to lower the boost if you want this one to last.
4. Wait 4-6 months untill several manufacturers come up with a set of kevlar frictions and meanwhile drive other car.

PM me you phone, I can call you tomorrow and discuss some specifics.

As mentioned above, all you need is the Technosquare ecu " limited flash ". In auto-mode, will shift before hitting rev limiter at wot. See Tinmans "0-120" video, link below. Tinman/Steve has a 5AT with SFR TT with that ecu mod.

agree with KenStyle 350Gt.... all you need is the L1 reflash by Technosquare. i think altered atmospshere does it too (not sure though). i also got the stillen vb done to my G and its so much better than factory. cannt see much dif. on D mode but on MM it so much crispier! It jolts a liltle with you shift it on auto. no lag!

 

I know you guys had some real problems with both the stock tranny and the Level 10 tranny, but could you elaborate on what you had done to the stock tranny before it had problems? Did you have a TC, VB or tranny fluid cooler? Did you log fluid temps? Also, with the Level 10 tranny did you have a cooler inline or log any fluid temps to know how hot things were getting? I am really interested in the results you guys had with the tranny and at this time your info has almost changed my mind completely about moving forward with a ST or TT setup on my 5AT car. If you are not comfortable posting on the site could you PM me? Thanks.
