Question
Vern, The auto runs fine for about the first 5 minutes. Then there is a delay in shifting from 1st to 2nd. Instead of shift at about 18mph shift happens at about 24mph. Then after a few more minutes of driving, there is slippage in 2nd gear. Fluid is full but hasn't been changed for several years. All driving done in city, below 30mph. Any ideas?

Answer
Hi Tim:
Depending on the mileage, you could have worn bands. Since the transmission hasn't been serviced in several year, before you go through an expensive transmission rebuild, change the fluid and filter and add Lucas Transmission Fix (24 oz.) for about $15.

Don't over fill your transmission. Make sure you tell who ever is servicing your transmission to leave the fluid about a quart low, so you can add the Lucas Transmission Fix.

Keep in mind, this will prolong the life of your transmission, but it won't repair the problem. It will save you from a $4,000 to 5,000 transmission job at least for a couple of years.

Expertise

Visit my website at: http://www.classytransportation.com/ I can answer most questions about autos built in the 60's 70's and 80's. Specifically, Lincolns, Rolls Royces and the Excaliburs. Mechanical issues and technical questions are my expertise. I also have a general knowledge of most older automobiles. Keep in mind, I can only provide answers if the questions are very specific and complete. Without details, I can only speculate and that's not good for solving your problem.

Experience

I have owned and maintained Silver Shadows for over 10 years now. I find most mechanics and even Rolls Royce mechanics have very little knowledge about these automobiles. I have researched these cars in quite a bit of detail and can pretty much tell you what is wrong, if you can describe the behavior in detail. I have saved quite a few RR owners a lot of money and aggravation due to improper diagnosis. I am the owner of Classy Transportation, LLC a luxury limousine service specializing in antique cars, classic cars, vintage cars and exotic cars.
