5 speed automatic shift points

how can you reset the trans? The shiftpoints are already in the PCM.
You are unable to "teach" the transmission to shift gears at some other points than allowed by the PCM. Under certain circumstances shifts will take place earlier or later - this include, but is not limited to: ambient temperature, trans and engine temp, engine load, A/C being on/off.
I had the battery disconnected for two hours when I was working on the car and nothing happened - it shifted the same way.

One plus for the Rondo 5 speed A/T: When you shift into neutral at speed, the transmission maintains the gear you are in until you shift back into drive, or it downshifts if you get too slow. I thought it would default back to the shift point of the speed you are going but it doesn't. I was driving today on a hilly section of road. I got the car up to 40 mph so that it would shift into 5th gear, then on a downhill section, I shifted into neutral. On a flat section, the car slowed down to just under 35 mph and I shifted back into drive. I was curious to see what gear the car would be in right after re-engaging the transmission I shifted to the auto stick mode. I thought it would be in 4th, because that's the gear it would normally be in at 35 mph but to my surprise, the car was still in 5th gear. Re-engaging the transmission was also smoother than I thought it would be....damn near seamless. If there was a bump, it was very slight. Now I can drive the car like I used to drive my stick: press in the clutch (or in this case, shift into neutral) on the downhill sections and then release it to go back up the hill or to maintain speed. Hopefully, I'll be able to squeeze a few more mpg out of this thing.

^^ Good god, Tubaryan12, are you that desperate to save fuel that you shift to neutral going down hill? Do you by any chance ask your passengers to get out and push going up hill?.

as for shifting to N. Yes, it will work well as long as you do not press gas before putting back in D. If you do - you will feel bump.
And minimum speed at which 5th would be engaged is 37 MPH (based on Rondos speedo) what would be around 35 MPH based on GPS.

This is referring to cross bars.
Tubaryan12, tell me - how can you get low fuel consumption if you still carry cross bars on the roof??

Shifting to N will not overcome cross bars. Nothing will...

[Tubaryan12]

Though I will agree that crossbars on the top of the car don't help, the shape and cross section of these bars cannot significantly add to the drag on the car.

Shifting into N may not overcome cross bars, but we don't know that. Got any data? Shifting into N will save vs not shifting into N. There is no doubt about that.

I will, however, remove the cross bars in the interest of science. I will admit, I am curious to see how much they actually hurt mileage. My guess is not that much.....but I've been wrong before.

****update****
Maybe I won't remove them. The ecomodders don't seem to think they add much:

I wish that were the case in my car. The absolute min. that my car will shift into 5 is 40 mph according to the spedo.

Not desperate, but if I can save, why not? It costs nothing to make the engine turn less times per mile.

(and yes, I do make them push...and pay for gas as well)

Tubaryan12,
no offense, I did not want to insult you. I had cross bars and can say for sure they add something. Probably 0.2L/100 km (what is hard to convert to MPG).
I do use N too, therefore I know what to NOT do while shifting back to D
But, not always N will save fuel... when you are going to stop, engine braking will do better job.

[Tubaryan12]

No offence taken. You'd have to to do a lot more damage than that to insult or offend me....lol. All I'm doing is making my case. You are correct...they should be off if optimum fuel economy is a goal. To be honest I did the math, assuming the edmunds test the ecomodders quoted was correct. With a 1% saving in mpg, removing the crossbars would save me about $20 per year. It's not worth storing them in my garage for that small amount. Maybe shifting into N won't save anything significant as well. We won't know until we try. I have also done the test weeks with shutting down the car every time you have to idle more than 10 seconds, and to my surprise, those couple of weeks, my mpg went up about 1 mpg.

What I discovered by using ScanGauge: shifting to N will save fuel (assuming you do not touch brake), but if you have to use a brake, manual shift to 4th or 3rd to slow down. This way it is using 0.0 L/hr, otherwise it is from 0.9-1.3 L/hr.

Shifting to N while waiting for lights change. This is a HUGE difference.

While waiting on lights with headlights on, blower on 2 it is using around 1.5-1.6 L/hr (on D), but when you shift into N it will drop to 0.9-1.0 L/hr.

I was raised in metric so I use metric.

It will be even more if engine cold. On cold start it will be using around 3-4L/hr.

[Tubaryan12]

So, according to scangage, our engines shut off fuel under engine braking? If so, that will change how and when to use N.

Your data on Shifting to N during lights is a good alternative to shutting down. I will employ both, depending on situation.

You keep talking like this, and I may be in the market for a ScanGauge myself.
