According to this page, the ECTi tranny was not offered in '00 on the I4 Camry.
"Opt for Toyota's four-speed electronically controlled automatic and you'll be getting an excellent transmission. The ECTi transmission mated to the V6 features an adaptive program that responds to individual driving styles. Drive more aggressively and it will delay the shift points for more spirited performance. Leisurely cruise around town and it will shift sooner for smooth, fuel-efficient performance.
Automatics in four-cylinder models do not benefit from the adaptive intelligence feature, but they do come with a little button on the gearshift lever that allows the driver to lock out overdrive. This keeps the transmission from shifting above third gear. We found it provided much better acceleration performance when winding along California's coastal roads or up and down mountain passes. We also found it helpful on many occasions heading down city streets for a quick trip to the market."
