The transmission died when I let it run dry, I learned an expensive lesson by never checking the fluid.
The only other things I replaced on the car where the general tune-up items and things I wanted to change for my own pleasure.
(K&N air filter, high performance spark plugs, high performance wires, high performance ignition coil,
Flo-master type exhaust system)
The 1983-86 Thunderbird coupe is one of my favorite cars. I have owned 20+ cars. I have recently bought my 3rd Tbird. I drove this car everyday, everywhere until someone turned directly in front of me, causing a T-bone collision and totaled the car.
This car had plenty of power after adding some minor medications that everyone should add to there car to improve fuel economy.
The interior is very comfortable and well laid out, and the car is very responsive. This made the car a joy to drive. I found this car to be very reliable if you treat it well and don't beat her hard.
Hence, I put more miles on the Tbirds than any other American vehicle that I have owned. These include a Lincoln, Caddy, 2 Impalas, 4 Ford trucks, 2 Buicks, Camaro, Grand-Am, Firebird, even 2 Dodges, 3 Thunderbirds, and a few imports that I don't care to name.
You mentioned you've done little things to improve your tbird's gas mileage... what exactly did you do? My 83 is terrible on gas and any suggestions are great. My email is dr_jrey@hotmail.com is you get the chance. Thanks!
I'm getting my grandmother's 1985 Thunderbird with 22,000 miles. I'd also like to know what you did to improve the fuel economy. Also, what are some things I should look at replacing and/or checking before I make it my everyday car? Please reply to this site or my e-mail, csbickmo@yahoo.com
