Yep I agree. It looks like its been shut for a while. I'll put the lube on it. Can you guys point me to another question? After I get the car warmed up, after 15 min of driving, when I get to a stop, and then proceed to go, the transmission takes about 5 or 6 seconds to engage. It's like I am inching forward, then it will catch. Nothing jerky, just a slide in. Fluid is not burnt or anything, but my gut says vacuum line, or needs a complete flush . Any ideas? Thank you.

 

There isn't any vacuum connection to the transmission. Doing a flush yourself or a drain and fill would be a good idea as possibly the fluid might be the problem. The new stuff would surely have more cleaning power and maybe it's a sticky shift solenoid that isn't applying enough pressure at low RPMs. Fresh fluid is always a good place to start.

 

Thats what I will do. Should I put Lucas tran treatment as well?

 

Change that fluid as soon as you can. I would simply change the fluid and not do a service station flush. Also, I would not add any treatment stuff till you've seen what the fresh fluid change has effected it.

 

IMHO, Lucas is a great additive, preventative and in some cases repair. I'm not a big fan of "mechanic in a can" but I've had good real world results using their products. I do run it in my transmission and use it on customer cars.

And when I recommended doing a flush yourself, I do mean YOU !! I used to work in fleet maintenance and we saw so many transmissions that were near or over 100K that had no history of being serviced or any driver complaints and when the driver went in for a "quick lube" they talked them into a flush with their machine and shortly after the transmission failed. Sometimes the grit in the fluid is what is holding it together.
Now that is my learned recommendation but I have to admit when I bought my 850 with over 250K on it and no maintenance history I couldn't stand the black fluid in the transmission and I did a home flush. It wasn't smart for me to do it but I couldn't stand the fluid and knew I was taking a chance. It's been a year now so I got off lucky and plan on doing it again this fall.

The two recommendations for doing the trans fluid. Either jack it up and pull the transmission drain plug and refill (approx 2+ to 3 quarts) with a short drive and do it three times or actually pull one of the cooler lines and spit out the contents into a container while adding fluid. Will take 9 to 12 quarts to see your fluid finally a nice light pink color.
On my 95 850 turbo it was the top line that is the output line from the trans that you want to put a hose on and stick in a container.
I found that the hose from a water softener is just the right ID to fit the cooler line. Had an extra coil of it sitting around.

IPD sells a kit which is nice since it includes new O rings and retainer. You can get them separately too.

Instructions with pictures. I just used a 5+ quart oil jug as it was already graduated on the one end.

I did the flush alone. I would allow the engine to idle until I saw bubbles starting to flow in the hose and then shut it down, read how much fluid was in the container and pour roughly that amount of fresh fluid back in. You need to do it three times minimum to get the fluid clean and possibly a fourth if it's still not the right color after the third.

 

For now I'm going to do a 3 refill job and put some Lucas in. I have a few things to address before I flush. I'm pretty sure I need a PNP switch, I think that's the name . I reset the codes but they came back on. It's only taking off slow at first, but then seems normal. Seems the more I drive and clean this Volvo the better it is the next day.

 

Clean it yourself or replace with new

For $9.00 I got a PNP switch at the salvage yard, pulled it my self which gave me practice for my car. Found an excellent write up for this installation. Looking forward to seeing what my copper contacts look like as opposed the other. Will stretch the little springs inside and clean. Well I'll write back after I give my self a day to work on it. Going to several salvage yards, really gives one an inside approach along without worrying about screwing up my car; even more finding out how these volvos tick. Fixed my radio today, I swear; the radio antenna was unplugged. Prior owner was........later.

My car has done the same thing since I bought it. I did the trans flush and it still has the slip. I'm looking for other options on what to fix. What's the PNP thing all about?
