in your opinion, if this is indeed mechanical probelm, why there would not be any warning such as harsh shifting ideling of transmission during some 500 miles since I had engine light came up?
Do you think it is possible to just replace teh torque convertor of the transmission, or there has to be entirely replaced?
1-Is the error code not related to th cluch part or torque convertor? then why replacing the rest?
2- do you receommend re-building of the transmission using the kits? is re-building has to be done by a shop that is specialized in acura or anyone deadling with Honda, Camry, etc...
3- what do you think is the best: Rebuild the transmission, or replace with another used say 70,000 miles one. The seem to have both one year or 12,000 warrante?
4-I was checking the link you sent me (directfix). they do not work! seems like only you have access
Do you have any recomendation on the best local shop in orange county for acura transmission repairs, diagnostics?
Please also send me some diagram, or simple instruction as to how I can drain my transmission fluid and check for debris.
