1963 Continental Transmission Questions

Hello Bill.

Thanks Again for all of the info! I have a couple/few questions I hope you can clear up for me...

When checking the transmission fluid level - should the fluid level be checked when the car/fluid is cold and the car is off or with the car running and at operating temp? If running and at operating temperature - should the car be in neutral or drive when checking fluid level?

What are the main issues with too much transmission fluid? I always here that is important not to overfill? What if you overfill "a little" while filling?

Is there any "issues" or negatives with this transmission to using products like Lucas transmission stop leak - stop slip if leaks and or any slippage occurs?

Main issue is the transmission has just been serviced (by a reputable company that specializes in classic cars - fluid change, new filter, new gasket) and over the past few times driving the car reverse is not positively engaging "quickly" as it should. When selecting reverse it is pausing from a few seconds to as much as 10-15 seconds before
reverse engages. This happened previously (before transmission service) and was "corrected" by adding more fluid (transmission was leaking pretty badly before service - still leaking a little even after service and gasket replacement). I think when the car was
returned from service the transmission was not completely filled? Other than that the transmission seems to operate just fine. 83000 original miles...

Regarding fuel (octane) - what fuel grade was the engine designed for?
Should I be purchasing Regular 87 - Mid 89 - or Premium 91/93? Should
I be adding lead substitute or additives for the ethanol?

Thanks Again!



Hi Robert -

The transmission level should be checked with the engine idling and at full operating temperature with the transmission selector safely in the Park position. A transmission that will not engage into gear immediately sounds like it may have internal seal leaks. For all of your other transmission questions you should consult with the technicians who have serviced or overhauled it and who are warrantying their work.

The engine in your 1963 Lincoln is a high compression engine that is designed to take advantage of the highest octane of fuel. I would recommend using nothing less. As for fuel, engine and transmission additives or lead substitutes etc., there are hundreds of these types of products available and thousands of opinions. Some of these products do actually help in my opinion but some are added too late to an engine or a transmission in an effort to eliminate a needed repair. Many additives can sometimes delay a repair and some only serve to make the owners "feel good" that they are "taking care " of their vehicle. I personally do not use any in my vehicles that range in age from 1954-1995 therefore I cannot offer a fair or helpful opinion in that matter.
