  1. Not an electrical engineer, but I feel like this would be theoretically possible. Maybe using an arduino or raspberry pi to help with the interface?
  2. Welcome! I would suggest that you spend some time looking through the how-to section of this site to get familiar with all the reatta quirks. Especially familiarize yourself with the brake system, which is quite unique compared to most cars. I'm a recent Reatta owner. mine is a red convertible I bought back in Oct. It was a lowish mile fixer-upper with a body in real good shape. This forum has been an enormous help to me with fixing all the problems with it. I need to take some better pictures of it though.
  3. I think the reverse gear is a red herring honestly. Started it up this morning and no symptoms at all. Shifted into reverse nice and smooth and no stall. It was quite a bit warmer this morning. I think it is an idle problem in cold temperatures. I think I'm going to clean the IAC valve and see what that does.
  4. I think I got the same kind you mention. This stuff
  5. I found this interesting and helpful article about different ATFs: https://www.cartechbooks.com/techtips/autotransfluid
  6. Yeah, I'll have to try that. The last time I drove it, I didn't have the problem. It has only happened twice so far, both on cold mornings. Next cold morning I'm going to try some of these things and see how it goes.
  7. I replaced the O ring on my accumulator today. So far no leaking but will have to keep an eye on it over the next few days. I did confirm the repair manual says nothing about needing to bleed the system after servicing the accumulator.
  8. Ah, I am guessing that is not the problem because it typically shifts rather gently.
  9. I have these two books. they are both in rough shape, but complete. The '91 manual I got from the previous owner of my '90 reatta. The info manual is not a complete repair manual. Didn't realize that when I bought it. Both are free to a good home, just cover shipping.
  10. I will have to try tomorrow morning when it is cold. The pan gasket does leak so I have had to top off the trans fluid. The idle seems right for being cold. Which vacuum line are you talking about?
  11. So getting ready to do a trans fluid change. I was planning on just dropping the pan, replacing the filter and then topping off. The owners manual says to use Dexron II or equivalent. Should I use Dexron III or Mercon V? I was going to use Dex III, but the Bottle for Mercon V says compatible with Dexron II. I think I saw someone on a different forum say not to use the Mercon. What do you all suggest?
  12. only seems to do it when it's cold. Not every time either. Maybe not transmission related. I don't know.
  13. Had a weird issue this morning when I went to leave for work. I put the car in reverse and it stalled. Started back up, but tested it a couple times and every time I shift into reverse it bogs the engine way down. Seems to be specific to the reverse gear. Thoughts?
  14. yes I did fill the reservoir that way. The level was right at the mark. The other day I pumped the brake pedal until the accumulator was empty to check the level, it was slightly below the mark.
  15. Yeah definitely not two O rings because the old one is on the old accumulator. I did also wet the O ring with brake fluid before installing it like the factory repair manual says to do.
  16. So was doing some follow up inspection of the brake system now that it has been some time since replacing my accumulator and bleeding the brake system. I noticed that the brake fluid level had dropped slightly. On further inspection, I noticed that brake fluid was weeping very slowly from where the accumulator mounts. I can't really tighten it. What do you all think? faulty O ring maybe? I did a search and could not find any forum posts with the same problem. Also, if I take the accumulator back off to replace the O ring, do I have to re-bleed the brake system? The leak is extremely slow as near as I can tell.
  17. So I do have a 98 park avenue with a series 2 motor. The sensor it has looks exactly like the reatta's. I don't know if it is the exact same part but it sure looks like it. I bet you could get a junkyard sensor from any GM 3.8 engine (which is pretty much any car they made throughout the 90s and early 2000s).
  18. Yeah yours does look different than the one on mine too. I actually just found a generic O ring that fit around the shaft right and then cranked it down tight. I thought for sure it would still leak, but so far it hasn't.
  19. thanks for that info. I'll have to check all that and log it in my log book. I plan to do a complete brake fluid flush every year so I can re-check it at the same time at least. I have not checked to see if the switch is leaking yet. Is that hard to do? The lights do go off pretty much at the same time. I do have the GM pressure gauge that you hook up in series with the accumulator so I could check the pressures. I picked it up off of Ebay. I haven't tried measuring anything yet, but might check my system against the numbers you gave.
  20. I went back and checked. I was thinking wrong, it was just under 45 seconds for the ABS and brake lights to go out and 62 second to full charge. That was after sitting overnight.
  21. If you beat me to it, would be interested to see how you do it. Likewise if I do something, I'll be sure to share.
  22. I need to procure myself a backup. On a side note, I've heard the 91 model year used a standard vacuum boosted setup. Is that true? If so are parts for those hard to come by and is there any reason why you couldn't replace the Teves mk II with that if it died?
  23. I need to do test number 1 again from the how to, but un test 2 I get two solid brake pumps before the pump kicks on again. sometimes 2.5. I only got 1 pump every time with the old one. so it's at least an improvement. I've thought about trying to rig up an led on the dash that shows when the pump kicks on, so I can get an idea of how often it cycles and for how long. After sitting over night it takes 30 - 45 seconds to fully charge the accumulator.
  24. thanks 2seater. I bought the Hydac new. Do they age sitting on the shelf or only with use? Either way my brakes seem to be working pretty well so not worried about it.
  25. Even with the straw setup I feel like I couldn't get all of it out of the reservoir, so I just had to pump it all out. It took me a lot of fluid, about 2 of the large break fluid bottles. I do have one more question myself. Does anyone know what the capacity of the Hydac accumulators is supposed to be? I know they are larger and it does seem to take a bit more fluid to fill it up, maybe almost 3/4" drop in the reservoir level. I'll have to get a more accurate measure tomorrow.
