Transmission want change gears,when take off

When an automatic transmission is slow to change gears when cold, it is usually due to low transmission fluid levels or fluid that has become thick and sludgy due to a lack of maintenance. It is important to check the transmission fluid level and condition regularly, as low transmission fluid and dirty fluid can cause transmission issues such as slow gear shifts and slipping gears. Additionally, low levels of transmission fluid can also cause the transmission to overheat and fail. If the transmission fluid is in good condition, then the issue may be caused by a faulty transmission solenoid or a worn out clutch. In this case, it is best to take the vehicle to a qualified mechanic to diagnose and repair the issue.

This is often times a sign of low transmission fluid or a faulty transmission control solenoid. As you know, automatic transmissions use pressurized hydraulic fluid to change gears or to stop showing 2nd

Did you flash transmission,could be the problem!!!

sounds like normal behavior

You have an internal transmission failure, have a transmission repair shop look at this and be prepared to have it removed for repair and rebuilding.

You obviously need clutch service,but you knew that

normal at start up when it is cold. once it warms up it should shift normal.
top off transmission fluid.

Several things could be causing your problem:

1. Auto transmission fluid is low
2. Auto transmission fluid needs changing; this is an area that gets neglected by a lot of people;check the fluid and if its brown or gives off a burning smell, it needs changing. Very old transmission fluid will cause slipping in the transmission; if this is the case, it should be changed along with the filter

Hope you find that this answers your question. Best of luck.

p.s. If you have the fluid changed, make sure it's done from the tranmission pan, not through the filler tube; siphoning through the filler tube can be hazardous to the transmission, especially cars with a lot of miles

Nope. There is a drain plug on the transmission case. It is a simple drain and fill. Odyssey transmissions do not have a filter.

Saturn says and I quote

there transmission fluid is not to be changed after the first change at 6000 miles.

Now I say it should be changed at every 30000 miles. If changing out the fluid doesn't work then you need to go to a transmission repair shop.
