Hi all, I recently acquired a 1991 Oldsmobile Delta 98 Regency Elite (whew) with 3.8.
I've been going over the car and I have a few questions. The car came with no owner's manual.
On the back brake lines there are 2 cylinders. One mounted in each line going to the back brakes. They are not supported by the frame or anything; they're supported by the brake lines themselves. They are about 8-10 times as big around as the brake lines and about 1-2 inches long. I notice that much of the brake line running to and from these cylinders look aftermarket, but it appears like whoever changed the brake lines took special care to include the cylinders when replacing the lines. It would have been easier to just bypass them.
Anybody know what those are?
On the rear view mirror there is a switch that says off, low and high. There is a wire harness running from the mirror housing to the headliner on the ceiling. I flip the switch but see nothing happening (except a tiny indicator light behind the switch that illuminates when the switch is not off).
Anybody know what that switch is for?
The transmission is slipping. The person I bought it from said they had to add tranny fluid to it (but didn't say how much or how often). But they said they couldn't see any leaks. I pulled it over the pit and it does appear to be leaking from both tranny cooler lines. Since the car has no operating brakes I haven't been able to test the tranny out much, but I have gotten it to slip in reverse. I assume it also does so in forward gears too. Does the tranny have adjustable bands? I'm going to change the ATF and filter and see if it helps.
It has an air ride suspension system with compressor mounted under the hood. This car sat for a year before I got it. I would think by now that pressure in the system would have dropped enough for it to need to come on when I brought the car to life. I haven't heard it run at all. How does this system work? Are there separate sensors for level sensing at all 4 wheels?
All in all it's a very nice car. Kinda ugly on the outside, but a nice large feel when I plop down in the seat. Hopefully I can squeeze some more miles out of the tranny with some tlc. The car has 173k miles on it. Motor runs like a top with old sludge in the oil pan (hey.. she's still in the test phase). The tranny seems to shift quickly between reverse and drive. It only slips when you're goosing it pretty hard (at least when it's cold).
Thank you for any help.
