Have any problems been noted on a '72 1800ES with automatic transmission that I should consider before purchasing? Where can I get an idea how much I should pay for this model? Would I be able to purchase a late model manual trans to replace the automatic?
Thanks in advance for any info you can provide, or please direct me to sources.
The main problem with automatic transmissions of this vintage is that they wear out faster than manuals. You can expect to visit the overhaul shop every 70,000 miles. The good news is that they were made by Borg-Warner right here in the USA, and they were used in some contemporary Chrysler and American Motors products. This means that parts are relatively easy to find, and most repair shops can handle repairs.
I have never replaced an automatic transmission with a manual, but it should be possible. The main problem might be the other parts you'll need, such as bell housing, flywheel, clutch and clutch pedal (and somewhere to attach it), and possibly support members and a driveshaft. All of these things are available in salvage yards, but you're talking about major surgery to install them.
The manual transmissions used on P1800s are very solid, and I would not spend too much time trying to fit a later model transmission.
All things considered, it would be easier to find an ES with the manual transmission already installed than to try to replace an automatic. If you do pull a swap, I'd sure like to hear about it.
Prices on automatic ESes are comparable with those on manual ESes. To get an idea what they're worth, check prices in ads in Hemmings Motor News, my web site and anywhere else you can find these cars for sale.
