Any transmission guys in here?

I'm having trouble with the tranny in a 90 Camry wagon. If put in D it will take off in high gear, it never downshifts. I can shift it down manually and then upshift manually with no problem. But then when I come to a stop, it just stays in high gear. This car sat in a guys driveway for a year with a blown head gasket and he didn't mention any previous problems with the transmission. It was rebuilt 15K miles before it was parked. I removed the speed sensor from the transmission and checked continuity and it shows infinite. I also don't get any noticeable pulses when I pass a strong magnet near it. Any one experienced this same problem and found the answer?

I'm not a transmission guy, but my '90 Camry DX had a similar problem--seemed to take off from a stop in high, could be shifted manually through the gears. The solution in my case was the shift solenoids. I had mine done at the local TSI. Total cost parts, labor and tax: $289. Good luck, and if you decide to do it yourself, I believe you can get the solenoid kit for less than $150.

I found the problem. Oversight on my part. I just replaced the motor and the replacement came with the complete wiring harness attached all the way through the firewall to the connectors under the dash. I used the harness that was on the replacemnt motor because the original harness had been hacked up in places. When I pulled the new harness through the firewall the connector for the transmission computer remained hidden on top of the HVAC and the hole for it to plug into on the computer isn't easily visible. I just overlooked it when reconnecting everything. I plugged it in and the transmission is working fine now.
