So is the pump running after every gear change?
Very easy to test, no need for any diag kit.
Just sit with the ignition on (engine NOT running) and count how many gear changes you can make before the pump runs again.
Simple question: Has it got the correct fluid in it?
I was almost on tow truck 1 week
back. it is behaving strangely with flashing 1 and 2 and sometimes, was not engaging gears.i found out that the new pump was not working. it is well running again after I had strap a cable tie over the big RELAY. I was able to drive flawlessly for 50km to the work shop.
the mech clean the contacts and change the relay.
the graph after the relay clean looks like this :
engine on idle mode
There is an improvement of the pressure retention as shown on the 2nd peak of about 6 minutes. the 1st and 3rd looks strange.
2 gear shift to one activate one pump.
MAR on without engine running
there is 3 gear shift before the pump is activated. able to shift up and down all gears.
It greeted me the next morning with short door priming....... before the relay changed and contacts clean, it was dead.
I was able to drive without any problem. I thought that all the previous issue has be solved.
The GEAR 5 will start flashing again after 2min of driving on the highway. there is no problem shifting in all gears.
is there any problem with the graph/pressure? What are the suspected culprit? can I ignore the flashing 5? my mechanic suspect its wiring problems.
There was a clutch and gear box changed 3 months back. High pressure hose leak and was changed too. The pump and accumulator are new. This is the 3rd actuator (used).
