in this vid you can see perfectly what happens in the top of 3rd when it starts to slip. at the 8 second mark at around 6200rpms, trans slips, rpms jump up to 7000, i let off the throttle a little to make the shift

I hate cars

I'm on my Droid right now so the vid isn't real clear. Most of the time you overpower the clutches, it happens at the lowest rpm full boost comes in at. You were manually shifting the whole time, right? Does this still happen when you shift at the stock shift points? Maybe it will be clearly slipping when I get back to the computer.

Its been so long since ive drove my car and use D instead of ss. Can anyone confirm at what speed/rpm the trans is "supposed" to shift at when in D?

This vid below, the car was in D. Trans tries to shift at around 6200 but slips to 7000 then shifts.

However, in this vid below (same scenerio), Im in D, the trans shifts perfect from 3rd to 4th

shizzzz.....that is slipping real bad ?

does it only slip at higher rpm or do you also see signs at part (1/2) throttle ?

libert69

iTrader: (7)

^only high rpm and only 3rd gear. we did over 30 dyno runs in 3rd gear so the trans took a beating

^^^ aaaah i feel you...

I still think you're fighting electronic issues. It holds fine and then neutrals out. I'm not saying it can't be slippage, it definitely can be but it's not displaying the normal pattern of slippage. How does the fluid look? It normally turns brown quickly once there's slippage. Good luck with it.

Inaccurate

Under wot, mine always shifts at 6500. On rare occasions, it will shift at 6700, 6800, etc. But NEVER has it shifted at less than 6500. This applies for all gear changes (1 to 2, 2 to 3, 3 to 4).

I hate cars

The sad thing is I couldn't answer the question because it's been so long since I've floored it.

fluid is still pink and does not smell burnt. Did not have the chance to change the fluid before I left to look at the drain plug though.

At this point, the auto trans is done for as far as Im concerned. Especially since I already bought a 6spd and JandR's clutch.

I do wish I had more time with the trans before the swap to really try and trouble shoot the problem. But, bringing the car home from NY from FL with a sketchy trans and weird shifting symptoms, it just doesnt make sense.

Thanks for the numbers Inaccurate

Even if those vids dont show typical signs of slippage, the car still throws the vsa error and goes into limp mode. One wot pull in 3rd throws the vsa error and the car needs to be turned off the reset. No way I could live with that.

Inaccurate

I see what IHC is saying. That is some weird behavior for it to let-loose so abruptly. I would think that slipping would be more of gradual "slip" (relatively speaking) into higher rpm. This is just a quick let-go. Interesting to say the least.

I dont think its possible but its a thought. Tration control was off in the vid where the supposed slippage occurred. If the tires started spinning the rpms would jump up. However, i dont think its possible to spin those tires at those speeds.

Majofo

Can this be TCC related?

Inaccurate

I support your decision to go 6MT.

After I developed the non-curable "hanging 2nd" disease, I can relate. I do think that we are pushing the oem ecu beyond what it was programmed to handle. The only real solution is to abandon the oem ecu (PCM) and use an aftermarket ecu to control the entire engine and trans.

For me, I am hoping that I can stay barely inside the oem ecu's acceptable limits to avoid the hanging 2nd. Because I hate using SS mode.

When I do the "Ecu Reset" of holding the pedal down for 5 seconds with the key on to reset it, I will have hanging 2nd disease REAL BAD (even with 1/3 throttle). But it seems that if I allow the computer to slowing learn that my car is capable of rev'ing quickly by slowly introducing the computer to this reality, the ecu is much less likely to hang in 2nd.

with the new ECU available, is it capable of controlling the trans yet? or is Rodney still working on that?

I'm willing to let you borrow my unit for your testings.

libert69

iTrader: (7)

idk

no trans control yet. Youll have to talk to him directly b.c after this episode with my car, he may be abandoning the trans controller


dreaded 2nd gear hang

Majofo

This is definitely a control issue

swoosh

iTrader: (5)

^^^ yea....it looks more like a control/solenoid/pressure sensor issue than a tranny issue....

if we can only plug in and control those factors, Justn will do a 5AT swap

libert69

iTrader: (7)

2nd gear hang is definitely electronic. whatever is happening in the top of 3rd is unknown. First time we have seen this

But, on the dyno towards the top of third gear, hp had a gradual decline once past 6k rpms. Thats not supposed to happen.

Inaccurate

"DOA
The time has come and gone
6spd swap underway"

This is the sign of a real man. You know how to man-up. I have always like this trait in you Bert

Majofo

Err.. Wrong. A real man doesn't give in until he finds the culprit, then fixes the problem. A real man also doesn't just throw parts at the problem until it's fixed.

a real man doesnt have a pink dog as his avi

Majofo

A real man gave the avi to me. I heard a real man gave you crabs as well.

Inaccurate

Thanks for the Texas generosity, but I'm good.

Do you have a modded Evo I can borrow ?

Majofo

Inaccurate

A man has to know his limitations. Some battles aren't worth fighting. No reason to piss into the wind.

Majofo

I don't have a modded EVO, but I might be able to hook you up with a lightweight, slightly modified '09 Kia.

Majofo

Bert's a pioneer.. sometimes a man needs to piss into the wind, because fuck it, that's why.

I'm just sad to see him put it down after all the effort, trials and success. Especially since this doesn't seem to be a mechanical failure.

Majofo

I definitely understand though, it can be a huge money pit and at the end of the day.. he just wants to go fast.

You can't blame him. To have a +600HP build and only able to put mid 400's down......

Inaccurate

Majofo,

Well, I can understand your point of view. The "5AT vs 6MT" route is a subjective thing. I can see how the argument could go either way.

My comments were really geared (no pun, really) toward the " "DOA - The time has come and gone" part. For Bert to have such good attitude to be able to accept what fate has given him. Bert put a lot into this most recent attempt. Put yourself into his shoes. This had to be a huge let-down. But, he took what fate threw at him with a smile on his face. Not many people can do that.

how deep are your pockets? Would u spend thousands of dollars to troubleshoot a tranny issue that ultimately you know it will never be able to handle the power that your built motor could put out?

I could pull the tranny, try swapping a spring, adjusting the solenoids, and waiting for an unknown amount of time to get rodneys trans controller up and running. These are all unknowns if it even will solve the problem

Id rather spend that money on 6spd and clutch that has proven to handle that power as a daily driver

im cutting my losses now

never have truer words been spoken

Majofo

Damn all of you have tight panties.. if you couldn't tell, you guys should know most of my comments are tongue-in-cheek.. lulululululu... :gheylaugh:

What I'm wondering is if the 6mt has ever been tested with this kind of power. I think you're going into uncharted territory with either trans. Autos are usually more durable than manuals once you get the line pressure sorted out. Your combo depending on which turbo ou currently have has the potential for 600whp if you ever choose to push it.

KN_TL

Kikazz was in the mid 500whp. It was good for the very short period of time he had it. Longevity is something we all figure is questionable.

Rodney was going to start looking into some stronger MT internals but I think Kikazz was his incentive. That went away with him totaling his ride.

Majofo

details?
