My daily driver is a '96 Buick Skylark. I’ve known for some time that the transmission had leaks, but it was minor enough to ignore for a while. Not anymore.
The car currently has 189k miles. I took it to an independent transmission shop to have it looked at. They said (A) it’s leaking from just about every place that it can leak, (B) it needs a rebuild/replacement, and © in the owner’s opinion, the engine is far enough gone that it’s not worth spending anything on the transmission. He thinks it likely that the engine will actually go before the transmission goes.
I’m not at all certain that he’s correct on that last point; in any case, I would like the transmission to last as long as possible without spending money on anything (besides fluid).
I live in Colorado Springs, where we have hills, often steep ones, all over the place. They can sometimes be avoided, but not always. I know that getting moving from a stop places the most strain on a transmission. What I’m wondering is whether it’s better for the transmission to have more starts on level(-ish) ground, or fewer starts but going uphill. That may be an impossible question to answer, but I thought I would throw it out, and see what the Dope says.
