I installed a superchip a week ago and was having problems with the needles jumping all over the place. I found a resolution to that problem...improper cleaning. So i cleaned all the contacts and used a magifying glass to look at all the contacts. All cleaned up. Now its seems that when i makes right hand turns it POPS into the neutral. I lose power for a second then it pops into gear? is it the chip or my tranny?

I think it's your tranny. If you want to be sure remove the chip and drive the the same roads that cause the problem and try to reproduce it.

I'm assuming you already checked the trans fluid level.

 

Installing a shift kit on thursday, so hopefully that will answer the problem...

 

Hi Patwrik,

You and I have already talked over the phone about this a couple of days ago I'm pretty sure, as I talked to someone who described that *exact* problem, as well as needing to go back and reclean the connector better, so that has to be you I spoke to over the phone, as nobody else has ever called us with exact those actions & symptoms.

That has nothing to do with the Superchip itself of course, as we discussed. What you are describing there is not at all a normal symptom or result of installing a performance chip, and we've never had that happen with any vehicle as a result of installing a Superchip.

Assuming, as LePew said in his response, that your tranny fluid is up to the correct level (which needs to be checked immediately), you could have a different problem causing fluid volume flow to be interrupted, in which case a shift kit *might* help, *maybe*, but I wouldn't count on it. Or, you could have shift solenoid or other problems, shift solenoid problems are known to cause the transmission to go up into neutral like that, and there can be other causes of that symptom as well of course. However, a shift solenoid is not going to cause this to happen *only* after exiting a turn.

When we spoke on the phone, you described this as happening *after* coming out of a low speed sharp 90-degree turn, it happens just after you nail it at full-throttle, after exiting the turn, was how you described it. When you did that, you described it going up to 5000 rpm and then going back down into gear. This is a perfect description of either the transmission fluid flow being interrupted due to the fluid being low and having just exited a turn and the filter not being able to pick up fluid, or some other cause of fluid flow interruption.

Because the Superchip was installed before the conformal coating was fully removed, at a bare minimum you need to also thoroughly clean out the slot on the back of the Superchip, as conformal coating has transferred over as a result of it being pushed onto the connector before 100% of the conformal coating was removed. This alone could easily be causing signals to not get thru properly, or have wierd oddball symptoms, etc.

Assuming it's not a connection-related problem, which it could well be, my next suspicion is that this is the result of going thru a sharp turn and nailing the throttle as you exit or right after exiting the turn as well, and then when you nail it, the filter doesn't pick up fluid continuously from the centrifugal force sloshing it around in the pan, so you get an interruption of the fluid flow and thus that symptom. Because it doesn't happen at any other time, this tends to point to an interruption of fluid flow, perhaps a combination of being a little low on fluid along with coming out of the turn and nailing it.

I would clean out the slot on the Superchip and make *certain* that *all* the conformal coating is removed from the connector as well, so that this cannot be an issue, and make sure the tranny fluid is full and see what happens. If it still continues after doing that and after installing the shift kit, then it's time for that automatic transmission to be properly diagnosed.

Good luck!

 

To be honest with you, i have never called, but then again thanks for the advice.

Hi Patrick,

>>>To be honest with you, i have never called, but then again thanks for the advice.<<<

OK, thanks for letting me know. Nobody else has ever called here before with that exact symptom and we've been in business a long time, so that combined with the fact that the person who did call us just called here literally a few days ago made me think it had to be you. So I assumed (uh-oh) that it was you from the symptom you posted, my apologies!

This literally could be anything like just making a sharp turn and nailing the throttle before the fluid covered the filter back up in the pan, overheated transmission fluid, the transmission fluid being a bit low, not having a proper connection between the Superchip & the PCM, or a shift solenoid problem or other issue causing an interruption in the flow of transmission fluid. Your basic symptom, on the surface, sure sounds related to either a lack of fluid flow or a shift solenoid, and my hunch is this is a simple fluid flow issue.

I would pull the Superchip and clean out the slot on the back of it, as anytime the Superchip is installed before 100% of the conformal coating is removed, some of the conformal coating *will* transfer over into the slot on the Superchip, it's not a question of if it will, the only question is how much will transfer over, if the Superchip is installed before all coating is removed from the connector. That's OK, this is very easy to solve, just point the Superchip module so the slot is facing down, and use a clean dry toothbrush to lightly brush off the little "fingers" (contacts) inside the slot on the Superchip. That will dislodge any bits of coating sticking to the fingers, and then blow out the slot to get the rest out. Don't use high pressure air, and don't blow straight into the slot, that will just ram the CF further into the slot. Just use normal lung pressure and blow it out using your mouth (or low-pressure canned air) making sure to blow from one end of the slot to the other, and switch ends several times, so you blow into one end of the slot toward the other end, and vice-versa, several times. Then make sure the connector is properly cleaned, and then reinstall the Superchip, making sure to tape it in place so it cannot work loose over time from going over railroad tracks, etc.

That will take care of making sure you have a proper connection, and eliminate that as a potential cause.

From there, take a look at tranny fluid level, and check to see if it has overheated too, as anytime you sit at a stoplight in summer, even for just 2 or 3 minutes that tranny fluid will always get well above 200 degrees, which is why we advise using an active cooler with a thermostatically controlled fan. That is the only way to keep those automatic tranny fluid temps under control at all times, with an active fan-assisted cooler. The transmission fluid should be a very light red in color, almost pink, and should smell clean, there should be no "hot" or burned smell to it, as that indicates being overheated, even if the color has not darkened significantly. Tranny fluid will only turn dark if it has been *extremely* overheated for a long period of time, you can still have red fluid that has been fried and lost it's properties, and thus the tranny won't always act right. We recommend using synthetic transmission fluid to prevent molecule shear & provide more consistent automatic tranhsmission operation.

This really could be as simple a matter as just taking a 90 degree turn at a speed that is high enough (and it doesn't take much in a 90 degree turn, 5-10 mph could be enough if it's done quickly) to make the tranny fluid slosh over to one side of the pan from centrifugal force in the turn for a couple of seconds. Then when you nail the throttle coming out of the turn, causing the transmission to downshift, it needs a lot of fluid in a very short time to respond, for the clutches to fill with fluid & execute the shift. That alone really could be the cause of this whole problem, just to let you know.

Just some FYI stuff, & don't hesitate to call us if you'd like to go over this.

Good luck!
