  • Low mileage and transmissions.
  • 150K is not low mileage.
    It seems the American public got what thy wanted.
    Less emissions, longer lasting, less maintenance.
    Now it just cost a bit more than in 1970.
    I will start with the wonderful transmission. Anyone old enough to have purchased a car PRE 1970 knows that a transmission fluid change was never, ever, called for in the maintenance book. Transmission fluid changes once again began to die off in the 90's. What happened from 1970 to 1990? Well, they stopped shooting whales and then synthetic trans oil came about. Pre 1972, Sperm Whale oil was added to trans fluid and changes were not typically called for. Once the anti-tree huggers stopped shooting whales, trans services came about. I cheated, I added LubeGard and ignored them. Beyond that, a trans cooler is not out of the question.
    As for the engines, better metals used, direct injection and easier starts means shortened cranking times for the start up.
    Synthetics oils also play a large part.
    However, in the old days, a yearly tune up was not unheard of. Now it goes out how far? And cost's how much? But you did get lower emissions and (ha-ha) less maintenance.

  • Re: Low mileage and transmissions.
  • You don't know what you're talking about. I've purchased and owned a number of pre-1970 vehicles with automatic and manual transmissions, and every one of them has had a manufacturer's recommendation for transmission fluid changes. Transmission fluid changes did not "die off" in the 1990s either (owned and serviced a number of them as well).

    It costs a bit more? Using an inflation calculator, a Chevrolet Impala that costs $4,000 in 1970 dollars would cost just over $26,000 today. The base price of a 2018 Impala is around $28,000, and without question the 2018 Impala has vastly more capability, reliability, safety and technical ability than a 1970 Impala. Given the level of sophistication of modern vehicles, you'll get a lot more for your money than you did in 1970.

    And a tune up on modern cars? On my 2011 STS it's a spark plug change at 100,000 miles. It takes all of about 15 minutes to change them out on either the 3.6 (which ours is) or the 4.4, and it's good for another 100,000 miles.

  • Re: Low mileage and transmissions.
  • Transmissioin fluid changes were indeed specified in owners manuals in the 50s, 60s, etc., however many owners did not follow the recommendations. Automatic transmissions of the era (not the 50s) also had replaceable filters (inside the pan) that were also specified to be changed.

    Sperm Whale oil was used in posi traction oil until outlawed by treaty. This is when the so-called limited slip differentials started causing lots of lock up related issues.

  • Re: Low mileage and transmissions.
  • I agree with Dean, I had never heard of the whale oil being used in a automatic transmission but heard of it being used in some of the posi traction rear ends And almost all transmissions right up now have replaceable filters, most are in the pan some are spin on.
