Hello and thanks in advance for your help:
I recently screwed up (that's how these things always start) by draining the transmission fluid pan while changing my oil. After noticing that it wasn't oil coming out, but tranny fluid, I let it drain and then put the screw back in. After changing the oil, I checked the owners manual and it stated that when you drain a tranny (for a 3VZ-E 4wd) to refill using up to 4.5 quarts. So, unfortunately i added 3.5 quarts, checked the levels (which lied at the time and said it was at the right level) and proceeded to drive a couple hundred miles. Every once in a while, I would check it, and it would say it was overfilled. So, I pumped some of the fluid out two seperate times. After I was having some problems with the car shifting into 4th gear, I decided to take it into Toyota and have a full transmission flush. They said that they gurantee that the tranny fluid would be at the right level.
Now that you know the background, here is the problem I'm having:
When I begin driving my car after it has been sitting for at least 2 hours, it will not shift into 4th gear until I have driven it for about three miles. When I first get onto the freeway and drive at 60 mph, it is still in 3rd gear at around 4,000 rpm. It even stays in 3rd gear if I ease off the gas, or even take my foot completely off the gas pedal. After driving at the high rpm for a while, it EVENTUALLY kicks down into 4th gear and drives completely normal for the rest of the time. Keep in mind that it usually shift from 3rd to 4th at around 3,200 rpm and around 50 mph when I'm accelerating.
If you have any ideas, I'd love to hear them.
To check the fluid levels, there is both a level on the dipstick for "warm" and "cold". It read accurate on cold, but then read extremely overful after I had driven it.
