Open Question

When accelerating out from a stand still the engine will rev to a high rpm, not shifting to the next gear. If you let off the gas momentarily, it will then go to the next gear. 2 WD, 1994

SOURCE: 1994 ford ranger extended cab 6 cyl fuel injected 2 wheel drive automatic

This year of ranger had a few flaws, In one case, a break power booster was robbing the vacumm, you can test this by plugging it off and seeing the differance, but you will have limited brakes. This model year had a problem with a vacuum leak on the manifold. You can check these in many ways, but please don't use starting fluid. The rear of the manifold usually on the drivers side where it seals to the block.
Also, in 2 other cases a cracked head has gave me the same problem. It is caused from a loss of vacuum.

SOURCE: 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.

Automatic transmission


I would be looking for vacuum hose leaks to the vacuum actuator on the transmission
what you describe indicates either no vacuum or a faulty actuator that causes a shift in gears in the transmission not to be effected
run the fault codes to see if any other sensor ot TCM is involved in the problem
this is all indicated by the changes that occur when you ease of the accelerator and it changes gears

How to reduce high rev in engine when accelerating


Assuming you have an auto transmission, your only choice is to ease off the gas when you want it to change gears. Then apply slight pressure on the gas to continue to accelerate.

2006 Ford Explorer shifts hard between 2nd & 3rd gears, both up & down, but shifts normal between 1st & 2nd, and in & out of overdrive. All was normal then almost not working the next


It sounds as though your valve body may have a lot of particulates that have entered into it causing the valves to act sluggishly. Unfortunately, this is a condition that can only be taken care of by your mechanic and is not something that the average person can fix themselves.

WHEN DRIVING AND THE TRANS NEEDS TO SHIFT ON MY 2005 VW JETTA 2.5-5 NEW STYLE THE RPM'S REV UP BRIEFLY THEN THE TRANS WILL SHIFT THE SHIFTING IS SMOOTH BUT THE HIGH RPMS WORRY ME.


when vw started to use the computer controlled gearbox system a criticism was the shift was very harsh,to counter this they made it rev slightly before changing.so that you know the system, try this out....without touching the gas.....put it in d and let the car accelerate to its max speed,stop,then use 1/3rd of gas (keep your foot still)and let it do the same...stop,then,if safe,put your foot to the floor,hard, notice when the car changes gear(revs/speed)then if you drive,only using the first1/3rd of the gas,the cars change pattern will alter to suit.......wierd it is.....

What is the ect button by gear shift


ECT stands for Electronically Controlled Transmission. When you push the button in, there should be a light on the dash that says "ECT POWER". This changes the normal shift times (based on engine vacuum, rpm, and throttle position) to a later point. This means simply that the engine rpms will go higher before shifting to a higher gear when you're accelerating. It helps build speed more quickly but uses more gas to do so. hope this helps please vote thanks
