About 10 month ago, I had my local Toyota dealer flush transmission oil at an expense of $109. After the change, my Previa will make big clunk sound as soon as I let the brake go from a stop to go. Did not know what it was, but check the transmission oil level. It was way above upper part of hot level. I drained it and about 4.3 quarts came out. The manual calls out 2.5 quart capacity. The moral of story, the thunking sound disapeared and convinced that this particular bad dealer did overfilled. Be cautious. |

Anybody knows what can cause the following problem: after the new (52kmiles old) transmission unit has been installed on my 1993 Mazda 929 the overdrive mode does not want to work. The following is observed: 1. I can not fix the “HOLD” button on the AT shifter in neither ON or OFF position 2. The “HOLD” sign on the indicator blinks. 3. When I drive the car, the engine does not shift to the 4-th (overdrive) gear. 4. After resetting computer the symptoms 1 and 2 disappear, but only temporarily -- until the car moves a few meters. Then it all (symptoms 1, 2 and 3 combined) starts over again. Probably, the problem is not a mechanical in origin but rather a failure of some electrical circuits. Mechanic who replaced the tranny has already inspected visually all the electrical connections of the transmission unit but did not find anything wrong. Anyone can help here? Thanks a lot! |

| you start moving the VSS sensor is suppose to kick in,letting the computer know you are moving.If the computer thinks the car isn't moving it gets confused.I would scan it and see what codes are. | |

I had a loose connection on 1 pin in a 4-pin connector to my fuel tank. You may want to verify that all connectors are tight and no pins are loose inside the connectors,,,sometimes just jiggling the connector will find the problem,,that's what I had to do in my case.. good luck hint: just work with 1 connector at a time see ya |

| I live in Maryland. Anyone used any service center for BG products? | |
| I am going with an oversize aluminum finned transmission pan for my 5.4 liter ford van , I liked the idea about putting a magnet to pick up small metallic shavings , I am considering Epoxing a magnet to the bottom inside of pan but am concerned about after a while the transmission fluid eating away the epoxy and maybe magnet obstructing fiter somehow , any ideas or comments ... thanks Larry | |
| I doubt it would block off the filter, but the epoxy could possibly dissolve and contaminate the oil. GM, looks like they use epoxy on theirs. Perhaps you could get a stronger magnet and epoxy it to the outside?? Just a thought. You could try it out before putting it in place. | |

I'd think twice about the epoxy idea.I use one of the best epoxies available to assemble heads to golf clubs.It can be easily broken down in boiling water(212*F). Better compare the temp of the fluid vs. the temp of breakdown.JMO |
