transmission problems

i have just recently changed the transmission pan and fluid in my 1995 toyota camry LE.... i drained the transmission and the transaxle transfer case... Not realizing that i had to replace the fluid in the bottom of the transmission for the transfer case, i just put fluid into the transmission through the dopstick tube... now after driving the car back an forth from a friends house down the street from me about 3 times i cant change gears..... i put the car into drive and my speedometer will go up as if i am driving but i wont move... i have been told by a friend that this might be a diagnostic problem where the car knew that there was no fluid in the transfer case and disabled my transmission.... what is the proper way of resolving this problem?

You probably blew the differential gears from no lubrication.

When you said "speedometer", I believe you mean the "techometer", which indicates the engine rpm, right?

There are couple possibilities:

First thing I would suggest you to check is the tranny fluid level. Although basic, but just check it to take the possibility out.

If that's ok, then I suspect some electrical problem. Mechanically, Toyota tranny is normally pretty good.

From my experience, the most cases I experience "slipping" or "no move" condition is due to insufficient fluid.

Good luck.

Probably time for a rebuilt differential/transmission

I vote for insufficient fluid as well if it was working ok before you changed it. It can be really difficult to read the trans dipstick for the correct fluid level because it tends to stick everywhere. I recently did some work on my wife's camry and thought I had the correct level in there 3 times and it was slipping too. Turns out it was short by almost a quart. Measure it cold and hot as well. Wipe the dipstick very well and take at least 1/2 dozen readings to be sure. You will probably find that fluid is covering most of one of the sides, but the other will be a lower reading. You may have to wait 20 mins after running it to get all the fluid to drain out of the dipstick sheath to get a good reading. If you are low, then add a pint at a time, run it again, then go thru the steps and re-measure since the tranny might suck some of it up.
