2007 M35 automatic transmission shift gears fine, but after last gear is shift the overdrive remains on. The RPMs seem a bit high when driving above 60. Any thoughts?


Sounds like the lock up in the torque converter is not locking up so your RPM's should be running about 500 rpm's higher. If I am correct either it went bad or not getting signal. I do not repair so I would say to take it to a transmission shop that you trust.

How do I stop tranny from shifting at high rpms?


Service the transmission and check the tension spring on the valve body to insure its not broken. Also on the side of the transmission there is a dash pod that is vacuum driven. Insure it works and the vacuum is hooked up. There is a shift cable that runs to the from the trans to the engine to kick down the shift on hard acceleration , this also sets your shift points. The dash pod is also adjustable with a small flat blade screw driver thru the vacuum inlet. If the RPM reeves up and then shifts, it is slipping and in need of rebuild.

Shifting high rpm


Follow cable/linkage from throttle body to transmission for kickdown and make sure it is well lubricated and moving freely at all points, especially at transmission . Patially seized or stuck will cause it to hang up like you are accelerating and trying to pass.

Shifting high rpm


These transmissions are very sensitive to fluid type. If the trans fluid is not Honda specific then drain and refill with Honda fluid. The "jerk" may be transmission related but could also be the rear engine mount or another engine/transmission mount. The rear mount is hydraulically operated. They are often bad and are not cheap. Be sure all mounts are secure, unbroken and that the rubber portions are not cracked from age or weather.

You need a new transmission modulator valve it controls the shift points of the transmission with vacuum.

Automatic transmission


Transmission will never hold the engine back if it is going through the gears properly.If it gets into high gear, eventually the engine will reach "redline" if you stay into it long enough. ("redline" for any engine is the point at which it cannot run any faster without harming itself.) DO NOT confuse that with proper shift points which should happen just before you reach max torque which happens way before you reach "redline" at which point you are way past the torque peak of the engine, and making no usable torque or horsepower. An example of this is a race engine with a max rpm limit of 10,000rpm.("redline") Depending upon the torque curve (determined by compression, stroke and type of cam grind) you would likely be shifting gears at about 7500 to 8500RPM not at 10,000.
Therefore, your shift points are like climbing a ladder. you get just so high and though there are more steps, you will fall off if you go there. Each time you shift, you are putting the rpms back into the usable power band, till you reach the next step, then start over again. If your trans shifts early the engine will lug and labor. shifting too late and it will quickly reach "redline" and self destruct or go "flat". In a conversion, you need to make sure that the electronics that control shift points are working within the usable torque range.
OR install a manual valve body and shifter and control it like a stick shift car, using your brain as the computer and a tach to tell you where you are.

With normal acceleration the 1st to second shift point should be around 2500-3000 rpm. Most of your shifts under moderate acceleration will take place at this same point or when there a light load on the transmission. Under hard acceleration the RPMs will climp higher due to increased power needs and the computer will shift when less power is needed or the RPMs climb to an unsafe speed say5000-6000rpms (depending on where yours redlines). Also going up a steep hill will raise the RPMs higher and goind down a hill will cause a faster shift at lower RPMs. These can always be altered by an individual owner by adjusting shift points, using performance parts and if you have problems (low tranny fluid/trans issues). Your trans RPMS are fine and will vary depening on how your foot accelerates. The shift pattern should be the same every time you drive slow/medium/fast/, look for changes in those patterns you will also catch a problem early.

High rpm shifting


Does your van have an "EAT" switch -- lower right hand side of instrument panel?

Pressing the switch in changes the shift points by making the transmission shift at a higher RPM.

If the van has the "EAT" switch and it is engaged, try pushing it in again to disengage it.

you can go through the ecm and reconfigure the trans control module,however there could be an underlying reason for you high shift points. it could be that you have a faulty engine speed sensor which sends the signal to the ecm to operate your transmission. my advice would be to check for any loose connections first. also your shift points are set to the power curve of your engine so if your having to throttle it to a higher degree it could be that the performance of your engine is not what it should be. if you can give me some more background on your vehicle i can evalueate it further
