Power to raido will not change from am to fm no dash lights trans shifts hard.

99to 2004 odyssey had problem with TCS solenoid
The solenoid screen that adjust and filters during shifts becomes clogged. After prolonged use( about the time you notice bad shifting) the filter is already clogged. It will throw a TCS light. Typical symptoms are bad acceleration, poor shifting ( typically 1-3 gear), hard shifting( banging when changing gears and hard shifting when putting it in drive. The issue goes away after the trans has cooled but comes back as the temp rises. change the trans fluid and then put new solenoid so it won't get clogged again,but there is chance ,your trans is on it's last leg,when you change the fluid,run the old fluid through paper towel and see how much debris from clutch material is on towel and, if there is any metal particle on towel,that is sign of bad transmission

the first thing would be to check the level and condition of the trans fluid as poor fluid level or aged fluid can cause these symptoms , when was the last time the fluid was changed ? As you have'nt mentioned vehicle i can only give a general opinion , if you post vehicle details i may be able to give a more detailed answer

My guess is the trans won't shift because of no power. There is a safety switch that is activated by the brake lights...no power means no lights and no lights means no shifting. Solve the power issue and you should have the trans working again.

For power it's time to get a probe and start at square 1. Battery? Have you tested it? Cables solid and CLEAN? These get overlooked a lot. Electrical is a hard one to solve over the net. But they are not hard to solve...just can be time consuming.

check the fluid and consider changing the trans fluid and filter

That light is telling you to have transmission serviced. not sure if it is the fluid or sensors. that is what a scan tool is for.

When the peddle is pressed really hard the trans is supposed to increase the shift firmness. The problem may be that the engine has some power problem which makes the trans look like the problem. If the engine is not operating correctly power wise hard shifting will occur.
If the car has a trans shift cable and it is adjusted incorrectly it will also shift hard. If the trans has vacuum modulator that is out of adjustment or going bad it will also shift hard. Many trans shops will test drive it for free so let the trans shop advise you for free and save some time.

have you tried to replace the tcu trans control unit.. it should be buried up under the dash.. don't confuse with ecu which might be there some where too.. good luck

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.

The ECT button stand for Electronically Controlled Transmission. In short, what the button does is change the upshift points for the auto trans. Normally, the 1-2 upshift is at 15-19 mph, pressing the button changes the shift mph form 15-19 to 19-22/23. More often than not, this feature wiooould be used if you are hauling a heay load, and the ECT gets you up to speed faster, via the longer time as mentioned above re the shift mphs. Not very useful with normal driving, it really does not do much without a heavy load.

when i bought mine the speedometer odomoter and raido didn't work
put in a fuse that wasnt' in got them all and now when u are driveing it shifts out of gears or sometimes it wont shift past first any ideas?
