Hey guys, new here. scouring the web for intel. I have an 02 toyota tacoma v-6 with the aisin A340F. Bit off more than i could chew a couple weeks ago and dunked my truck in water. not smart. i know. Ended up with milky trans fluid. So i dropped the pan, cleaned out the screen best i could, cleaned the magnets, disconnected the return pipe from the radiator, cleaned out said return pipe, and flushed out the milky fluid with valvoline multi-car import synthetic, certified for dex II/III and T-iv (according to their website PDF). I needed a little more though, and my small town autoparts stores didn't have anything, so i topped it off with Mobil 1 synthetic ATF Dex II/III certified.
I was out of town at the time, and had to return home, 1800 miles away. The transmission acted very well on the highway. Smoothest it's ever run. However, in that time the truck started to develop a very hard shift, but only when cold. The shift from 1-2 and 2-3 is alarmingly rough, but once the fluid is up to temp is almost entirely goes away. It also has an abrupt engagement from P-R and N-D which more or less correlates with the hard shifting when cold, but also happens sometimes at random.
I had come to the conclusion is was the 1-2 and 2-3 shift solenoids. perhaps the water is causing a bad connection, and the thicker cold fluid plus the bad connection is inhibiting their action?
However, I was told it could be the valve body, although they couldn't tell me exactly what was up with the valve body.
Does anyone have any ideas?
Thanks in advance.
P.S. one last thing. I didn't disconnect my sway bar when taking off the pan, and it made it very hard to put back on. I used toyotas FIPG gasket maker, as the FSM calls for. I'm afraid i may have knocked some of the wet gasket maker off, and it could be caught in the screen now. Could that cause the symptoms i'm having?
