Problem after transmission fluid change

[Francois850]

I just want to add a few comments.

- There is a universal rule in car repair, whenever a new problem surfaces after a repair job, 99% of the time, the new problem is caused by the repair.

- Your car is 1997 850 with 35K, trans problems should not happen.

- The 850, S/V70: for a simple drain/refill, it takes about 3.3 qts to fill it back up.

- If you do a flush (disconnecting the upper cooler line), there is a chance that the clip was not reconnected properly. The clip has a THICK side and THIN side (look carefully and you will see). The THICK side of the clip faces the radiator.

-Agree 100% with first comment.
- My car has about 115K, transmission was replaced 35K ago, I do not know if it was rebuilt or used unfortunately. But, before replacing fluid, it was giving me no problem.
- I did not do a flush, just drain a refill several times.
- I do not see any cooler line from the transmission, all I see is a line connecting the top of the radiator to the bottom.

This is not right, I wonder if whoever installed the transmission failed to hook up the cooler lines. There should be a line from the trans to the top of the radiator, then from the bottom of the radiator back to the trans.

Very interesting, I was wondering what was the purpose of that line.... makes no sense. Any idea where I could find a nice picture for the correct connections?

I realize you still don't know what's wrong but obviously no transmission fluid cooling might explain why the trans burned out.

Here are some pics from the engine removal tutorial posted here by wheelsup:

A look in from above, only 1 line in place:


If you go to Volvopartswebstore.com and look up the trans lines, there will be an excellent schematic from the parts catalog.

Did they loop the line out from the trans, right back into the trans? They owe you another transmission ...

Well transmission was working fine without it, believe it or not till I change the fluid so I believe we are dealing with 2 issues. I can't believe they did that, I have a way to find out who did it and will go after them.
I totally see how it's supposed to be linked now, thanks so much. When I was reading about the flushing method, it did not make sense to me and now I know why thanks to you and the pictures.
I can't see if they looped back the line of the trans back to itself but I am sure they did, I believe I can see only if I remove the battery.
Anyhow, what ever happens to this trans, you caught something huge, very well done!!!

Having a hard time identifying the parts, what I will need is the part # for each line, 1 in and 1 out, full assembly.... if someone knows the part # for each, would be helpful. Thanks in advance

Yes,
When reverse engineering like that comes into play, things would seemingly work well (but for a season...)
I would go after the Wizzard(s) who experimented that on my property and make them pay (tax and lots of interest included)

Agreed, I am still in complete disbelief.... UNREAL!!! What were they thinking??????

Not saying I would buy from here but here are the part #s

If this is your engine B5202FS, please see attached for parts.
If not, let me know exactly which engine you have (there may be a difference) and I will post a different PDF.

We'll make it fly again

Thanks
