| Thank you!! I will call the mechanic tomorrow and fixing it will give us the time we need to decide on which new car to buy. | |
| Hi all -- I just bought my first CV -- A 1992 LX with leather and the whole bit. Bought it at an estate sale. Just before the previous (and original) owner died, he had the AOD tranny rebuilt at a national tranny chain. It accelerates fine but I find it decelerates slowly (especially at mid to higher speeds). When I take my foot off the gas, it takes a bit too long for the car to decelerate without having to use the brakes. Tranny shop said that the rebuild has to "break in" but I don't really buy that. Any comments? Is this just a factor of the mechanical nature of the AOD vs. AODE? I'm comparing the tranny to a new Japanese tranny, so maybe I'm just not used to a mech AOD. Otherwise, the CV has got to be the best used buy going! | |

"When I take my foot off the gas, it takes a bit too long for the car to decelerate without having to use the brakes." If you want more "engine braking" take it out of 'Overdrive'. When in O/D and you take your foot off the gas, it's really in "COAST" until you get down to 37 mph, then the transmission shifts down to 3rd. |
|
| Wow, thanks for that. I didn't realize that OD wasn't supposed to shift until it gets way down to 37mph (which makes a lot of sense now). Any problems if I shift to D at higher speeds? Or it it better just to brake? I suppose brake repairs are cheaper than transmission repairs. | |

Does to '03 model has the TSB about gas tank safety? If it does, can you just bring your car in and have the dealer fix it for free - I assume this is a very easy fix since Arizona police can have their cruiser fixed in a few minutes. Thanks |

| Gas tank issue has been flogged to death on this board. Use the search to find answers. | |
| Usually no. When in pursuit, the police usually lock out of O/D for better control. In my experience, I've locked out of O/D at 60 mph while descending a steep road without any problems. Last time was coming out of Lake Tahoe. | |
| I'm glad that there shouldn't be any problems doing this, but did you shift from 60 with an AOD tranny? The reason I ask is that with AOD it goes from OD to D to 1. I get nervous that I might accidentically shift from OD to 1. An electronic lockout would be better, but what can you do. On an unrelated note, does anyone have a good cheap source for '92 headlight lenses? Mine have turned yellow from UV. | |
| Ford engineers took this possiblity into consideration when they designed the AOD tranny. The result is when you shift from OD to 1, the "brain" of the tranny will not let the engine over rev by putting you in the appropriate gear depending on your speed at the time. Let's say your are cruising at 60 and the selector is accidentally moved to 1, the tranny will shift to 3rd and when the car slows to about 40, shift to second, and when the car slows to about 25, it will shift into first. | |
