messy tranny flush
I decided to do a tranny flush on my 2001 xk8 5HP24 transmission. I did this before on our 2001 Volvo.
First I drain the fluid, remove pan, replace filter, new gasket and reassemble and add fluid till it drips out. Put fill plug back in. Holding that thin gasket onto the pan and installing it is a PITA. The fluid was black, and the magnets had lots of black stuff on them.
Now to flush, I disconnect the top pipe to the radiator and connect a hose to it to collect fluid in a catch pan when I start the engine.
Oops. The top hose is not fluid coming from the tranny, it is the return to the tranny. In the parts diagram the top pipe is labeled oil cooler return. That should say transmission return line. The bottom line is labeled oil cooler output. That should say oil cooler input
Of course I now have fluid all over my driveway. Throw down the absorbent and reconnect to lower pipe. Fill tranny with fluid, and flush 3 times. Used around 14 qts, yeah ( ~$250). The color of the fluid does not lend itself to know when it is clear in the black catch pan. The best way is to stick your fingers in it and then look at the fluid on your fingers.
Fill with fluid, tun engine, add more fluid, run through gears, watch temp with IR gauge. Fill correctly.
Oops, I stopped the engine before I put the plug back in. Another spill of fluid. And I get it in my hair as I put the plug back in.
Car is on jacks and I'll go get 3 more quarts to fill correctly tonight.
Ordered what I thought were drain and fill plugs. I was correct on drain plug. Still searching for part number for fill plug.
