Is my trans dead ?

It is like a small shock absorber, one side mounts to a bracket on the engine and the other side to the K-frame. Automatic cars don't get them because the transmission shifts smoother than manual cars.

Yes the filter is new, perhaps I made 600 km since.
The car had 156000km when I bought it, in really bad shape (turbo dead, no air filter, ...)

I changed everything (MP gasket, S60 turbo, MP engine supports, TII radiator and intercooler, ECU, timing belt, ported exhaust manifold, spark plugs, filters, bigger sway bar, rear discs, shocks, 16" wheels, new tires ...)

May be the trans was old and didn't support the bigger turbo ?

OK thanks Richard

Here's a look at what an original bobble looks like, and where it mounts to the trans & the K-frame.

Thanks
I phoned to a buddy who told me that the filter may be clogged because I don't use the car enough (twice a month).

this whole thing sounds like junk may have gotten into the valve body. If I were in your shoes I would remove the valve body and take it to a transmission shop for a rebuild and then go from there. Much easier than pulling the trans.

I have a cheetah manual valve body, would it be useful to use it with the problem I have?

Is it easy to install ?

Possibly, but maybe the transmission was just old and tired from the start, you'll never really know. I have heard that the automatic transmissions are limited in how much boost you can run, but I have also heard that they can be modified to work with higher boost.

I don't know enough about it, but I think most of the modifications are dome to the valve body and the servo(s), if you find someone that sells these modified valve bodies it would be a LOT easier to have that shipped to France than an entire transmission, the other parts you'll need are high performance clutches, again, much easier to ship than an entire transmission. Then you have to either rebuild it yourself or find a local shop willing to do it.

If you have a spare transmission you could use that one as the rebuild, while using the current transmission until the other one is finished - assuming the current transmission is still working enough.

You could use the manual valve body, but I don't know how well it will be for daily use, I'd expect your fuel economy to suffer a bit.

Personally, I'd start gathering parts to have the extra transmission rebuilt.

I have "heard" people say not to change transmission fluid because the new fluid loosens up old settled junk inside and clogs things up even more. It could just be an old wife's tale because people don't understand how the transmissions work, or maybe it was true of the older transmissions but not so much anymore, or maybe it's 100% true - I don't know. but for the price of a new filter, gasket and fluid I'd give it a shot. Don't think it could make anything worse.

Thanks Richard
I'm going to follow your advice and find the parts I need when I know them.

After I leaved my job, I was so angry that, even with the night falling, I ran the car.
Once again I could not use the reverse, but once the car was outside I checked the fluid level as it was suggested me here and it was low, my mistake.
Then I drove the car and didn't experienced the problems I had.
In a few days I will check for the reverse again.

I still think however that my trans has a problem, since it is not the first case that the reverse doesn't pass.

Next days will show, if things go better.

My cars seems to collect all the problems : sunday when I started them, I had fuel leaks in both (not at the same place though).
The one I'm talking about has also an oil leak, and sunday I drove it with a very low oil level. I really hope I didn't brake something (crank journals ?) inside the engine.

Thanks all for your help.
