Ive been reading on the bmw rangerover and jag forums that they are having success with doing these fixes. Link to comment Share on other sites More sharing options...

20pounds Member 180 Member For: 16y 1m 23d Gender: Male Posted 14/06/15 09:11 AM Author Share Posted 14/06/15 09:11 AM Yeah it seems to fix alot of the issues with these transmissions and it is pretty simple to install. From what I can gather its caused by loss of fluid preassure due to valves that are not sealing very well in the valve body. Im going to do a gulf western fluid change along with the zip kit,solinoids,new seperator plate for the valve body,pan,filter and a new heat exchange. Im not sure yet if ill need some programming done for the new solinoids. Link to comment Share on other sites More sharing options...
