93 camry le auto trans problems

[blk924s]

I have a 1993 LE wagon with 223,000 miles on it. Just recently, the automatic transmission will slip out of gear into neutral after coming to a stop or when climbing a hill. Most notably, it does this only after the engine and transmission have warmed up a bit. After moving the shift lever in and out of the various gears a few times, it sometimes engages a gear. The fluid level is full.

I haven't owned it for many miles, so I don't know how often the fluid was flushed and changed. I've heard there is a transmission fluid pump that can fail intermittently and cause this problem, and I'm wondering if that's happening once the car warms up. Any ideas? Thanks very much!

I also have problems with my 95 camry. But it is not that serious like yours.
I warm up my car by shifting from N,to D, 2, 1, R and back to P for a while, and after that the transmission feels better.

I also want to flush my transmission, so, let see................
