Need 4r44e info please.

Ok I have a 2000 ranger 4x4 with I believe a 4r44e auto tranny and 31x10.5's. I need to know a basic run down of how this thing is supposed to work under good performance OD included. I have never owned a vehicle with an electronically controlled tranny before so I don't know whats normal and whats not. It jus seems when im cruising through town between 35 and 40 I should not be at 1800 rpm, it seems like its holding the gear to long. I just want to know what is supposed to happen while normal driving conditions are taking place. So far the tranny fluid is pink and not burned I changed it and the filter myself about 10k ago, it shifts fine into drive and reverse takes about 1-2 seconds to engage. Thank you in advance for any info.

1800 seems a little high, but it could be how the trans is programmed to shift. Most manufacturers define preset shift-points to avoid lugging the engine by shifting too soon. I have a '10 Ranger with the 2.3L and 5-speed auto. It will hold in 4th w/o torque lock at anything below 46mph. Once it hits 46, it drops consistently every time as long as I'm not under a heavy load or more than about 40% throttle. My suggestion is to find a stretch of road where the traffic is light. Drive the truck to the indicated speed above and slowly accelerate to see at what speed the trans shifts. Try this several times under as close to the same throttle position as possible. This should give you an indication of where your preset shift-points are. If the numbers vary more than a few mph in either direction, you may have some issues with the transmission.

Thanks for the reply, it seem like sometimes it will shift and sometimes it will hold the gear or delay lock up for no reason at all. I will see if the long stretch of road gives me any info.
