Yep did all that. I might try disconnecting the battery terminals for a longer period in case there are caps designed to filter the supply in the ECM that might be discharging slowly and preventing a proper cold boot of the ECM when the battery is reconnected.lannvouivre wrote:Yes, there are magnets.
Have you let the car run for a long while? When the battery is disconnected, the fuel trims saved by the ECM all get cleared and need to be "relearned." Takes 15-30 minutes, usually. You may also want to clean the throttle body. A clean throttle body and sometimes MAF will bring the current state of the car closer to the base settings of the ECM.
So the pink spot is the new fluid? I thought the Toyota stuff looked clear - at least that's how it looked when the Vibe was new. It does look dark now.vibrologist wrote:I have done the drop the pan ATF replacement using Toyota T-IV fluid. There are 2 magnets in the pan.
I think I didn't have the correct definition for stall speed in mind. What I intended to say is that the fluid being old may cause the converter to grab at lower rpm and therefore tug a bit more on the drive train when idling in gear.
change the ATF. This is how mine looked: viewtopic.php?f=30&t=43476#p507231
Yes I agree it never hurts to change out the fluid. That said I have the Toyota Automatic Transmission Training Notes (primary designed for service techs) and it does say there that with modern fluids color is not a major indicator of failure due to the newer fluids and the materials that go into making up the clutches and bands on newer vehicles. Consistency is more important than color - for example tacky fluid.vibrologist wrote:The new fluid is at the tip of the funnel. The old fluid looks dark on the paper but it was solid black when it drained into the bucket.
The manuals are getting more confusing every year. The reason is they are written by lawyers to protect the manufacturer. Some manufacturer's talk about "lifetime" fluids. What exactly is the definition of "lifetime" for a car?
Well it has been a while since I disconnected the battery. I agree initially the idle was very rough sometimes at stop lights and felt like it was going to stall although it never did. It has smoothed out from where it was but does not feel quite the same as before. Another possibility is that the really rough idle after the battery was reconnected caused the mounts to degrade slightly leaving more vibration that before.tribones wrote:My car has a rough idle after I disconnect the battery.

I have put it in neutral to rev it up - its never actually stalled on me though. After a couple days it always rev'ed fine. I have an 05.
My '06 Vibe does the same exact thing when the battery is disconnected but it actually stalls at a stop. It will Idle very poorly until it stalls (never while moving thank goodness) and after that it will run as if nothing ever happened. This happened with both my old and brand new battery, I'm wondering if something is a bit off with a CM.tribones wrote:My car has a rough idle after I disconnect the battery.
