Is something wrong with my transmission?
Ive noticed recently when i take off from a stopped position, the rpms rev up to 3 (3000 rpms) when i take off, its not a loud revving but i do notice the quick movement of the needle up to around 3 k rpms when i push down the accelrator.
The car always move forward and accelerrates although a little slower sometimes but i do move forward. I always take my foot off when i notice the revving and doing normal driving the gauge reads between 1 and 2 rpms as i dont drive this car on the freeway hardly at all and its rare that i drive over 50 miles an hour.
It doesnt rev during normal driving, just when i take off from a stopped position and it seems to switch gears without jerking, although i have started shifting gears manually when i go up a hill sometimes and i never used to do it before it always did it on its own.
Is there any type of preventive maintenance i SHOULD be doing.

what happens if you don't back off the throttle when it revs up to 3000? does it keep revving to 4000, 5000? does it peak at 3000 and then pull the rpm back down until the speed actually justifies 3000rpm?

Ok i just went to the store and back and it revs up to 2k not 3k and the car does continue to accelerate and it does start to go gradually higher but only up to 2 -1/2 not 3k, 4k, or 5k.
When im going say 35 mph it hovers around 1.5 but thats after i take my feet off the accel and the speed of the car goes down.
i just dont remember it junping from a idle speed all the way up to 2k like it does now, and like i said i do hear a revving sound but not a real severe sound.

i mean it's hard to tell what's what on an automatic since a) the torque converter blurs the speed-rpm correlation and b) you don't necessarily always know what gear you're in. you'd probably have to take a well-narrated video for us to really know what's going on with it.

well i guess im just trying to stop a small problem before it becomes a big problem.. i mean from the inside i can hear the revving sound, but a friend of mind from the outside said he didnt hear the revving like you hear on some vehicles that rev real loud and dont move for a few seconds, then jerk forward before taking off.
somebody told me about some product from lucas that keeps your transmission from slipping? any precautionary suggestions.

1. Start engine and warm it up to normal engine operating temperature.
2. Turn ign switch to "OFF"
3. Set A/T mode switch to "AUTO"
4. Set O/D switch to "ON"
5. Move selector lever to "P" position
6. Turn ign switch "ON" (do not start engine)
7. Power indicator lamp should come on for about 2 seconds
Then:
1. Move selector lever to "D" while depressing brake pedal
2. Turn ign switch "OFF"
3. Set O/D switch to "OFF"
4. Turn ign switch to "ON" (do not start engine)
5. Move selector lever to "2" position
6. Set O/D switch to "ON"
7. Move selector lever to "1"
8. Set O/D switch to "OFF"
9. Depress accelerator pedal fully and release it
10. Check power indicator lamp
Codes:
There should be a longer start signal followed by 10 shorter signals, note which of the 10 short signals is longest
All flickers the same: self-diag OK
1st flicker is longer than others: revolution sensor circuit
2nd flicker is longer: vehicle speed sensor sensor circuit
3rd flicker is longer: throttle position sensor circuit
4th flicker is longer: shift solenoid valve A circuit
5th flicker is longer: shift solenoid valve B circuit
6th flicker is longer: timing solenoid valve circuit for non limited slip tranny(89-94GXE); overrun clutch solenoid valve circuit for limited slip tranny (some, maybe all auto 92-94SE)
7th flicker is longer: torque converter clutch solenoid valve circuit
8th flicker is longer: fluid temperature sensor and A/T control unit power source circuit
9th flicker is longer: engine speed signal circuit
10th flicker is longer: line pressure solenoid valve circuit
lamp does not come on: inhibitor switch, overdrive switch, and throttle position switch circuit
2. Turn ign switch to "OFF"
