Hi! My first post in this OIL forum! OK, I bought a 1991 Oldsmobile Toronado (base). 100K. It hasn't been started in 10 years. It was driven by a lady (a mother), their house appears well taken care of (nice suburb in upper Illinois). It was kept in the garage all that time (that's a big plus!), even I see some little white stuff with mouse popo on the engine (by the thermostat). It barely has NO rust (just little in underbody edges, appears this was never driven in winters). I had it tow to my house. Since it was real dusty, I lightly washed it right away the next morning (while it was 10Â°F), with warm water and soap, from the house faucet (e.g. water softener). That was about a month ago. It's now sitting on 4 jack stands (right where the jacking spots are), with car cover and freezing. It didn't include a car manual. First thing I have to do is drain the gas out (1/2 tank full). I got the relay switch and will be using the gas tank pump. Then, obvious, put some fresh gas in (with a 5 gal red tank, with MMO). The EXCITING next thing is MARVEL MYSTERY OIL !! I wasn't made aware of this oil in my 50 years!? Toronado has always been FRONT WHEEL DRIVE (1966 - 1992). Can someone tell me exactly what kind (name/model/specifications/capacity) this transmission is? You know, the internet is confusing. Some say this is a turbo (yet, my car is NOT a "Trofeo")? I want to FLUSH the old transmission fluid out with new fluid (isn't this called "fluid exchange"?). The transmission fluid is dripping like water when I pulled out the dipstick. Also, I want to FLUSH out some of the other fluids, so I am going to list what I gather to use specifically for this 91 Toronado. Yes, I am asking to please correct me here. Engine: will start out with Quaker State conventional oil (10W-30) for few hundred miles (mixed with MMO), and then switch to synthetic-blend Quaker State High Mileage. I am Quaker State guy for many years, sorry. Not sure about how often to change the oil (3K as old times, or is it now 5K, 7K)? I just buy AC Delco filter. ATF: only use Dexron III / Mercon (plan to buy AC Delco brand) Coolant: only use GREEN conventional coolant (I have looked all over for Peak GREEN, NONE of the local retailers has those! Only two online that I find are Amazon.com and Walmart.com. Outrageous freaking, Walmart.com is selling it for $106 a gal!?!?) (So, I give up; plan to buy Zerex original GREEN) Brakes: only use DOT 3 (I bought Peak brand) Power Steering: use regular power steering fluid (I bought Peak brand) Now, my question is HOW to flush the transmission fluid. Well, I have watch hours of YouTube on this topic. Some use natural "gravity suction" (most are saying this method does not work, false statement?). Some use pumps. Some varies. So, this is what I have come up with (again, correct me here, and explain why) 1) Take off the lower line connection from the radiator (that would be TO the transmission) 2) Find a hand pump to pump NEW fluid through that line (just to get new fluid on that particular line) 3) Leave that connect open of that TO on the radiator, that will be use to drain the old fluid (into a bucket), and cap the TO line (to keep the new fluid in the line) 4) Now, take off the pan and replace the filter 5) Clean the pan (and magnet) with brake cleaner 6) Put pan back on 7) Pour transmission fluid in the dipstick (~2 quarts) 8) While leaving the funnel in the dipstick, start the engine 9) The old fluid should be pouring OUT into the bucket, I keep pouring IN the new fluid in the dipstick (pour "equivalent" to what's spouting out). 10) When the new fluid is coming out into the bucket, then I shut off the engine 11) Close up everything, check levels, drive car around, check level, etc How does this sequence look? Most of the YouTube suggest replacing the filter after the flush. But, I am thinking since everything starts from the pan (and the TO line capped), so I just keep pouring the new fluid in the dipstick (that goes directly to the pan, doesn't it?), that will push (flush) anything ahead of the pan, including the tongue converter. So, thus #4 before flush. Correct? I was hoping to do all flush before starting the car for first time, but it's winter in Wisconsin now! Sorry if this is long, but just want to put everything out right away.
