as you all know i have a boosting problem (atleast i think it is) however i have noticed that on every start up i get the power light flash 15 times.

 

when driving i have noticed that third will only come in if the revs are fairly high. Fourth (overdrive) is fine .......... so far

 

i have also tried counting the gears yesterday and i swear on numerous occasions it felt like i got 5th????!

 

now obviously this is not fifth so something must be slipping

 

when i bought the car it had an aftermarket gear shifter without the overdrive button.....

 

i did find kind of think this was odd but i had presumed the older owner did not know about preserving the gear box by leaving over drive off through towns or when changing gears alot and to only use it when cruising at a constant speed.

 

Now that i have access to the overdrive button i have noticed that if i do 70 with overdrive on and i turn it off the car will go into 3rd........... however the car vibrates like mad when done so.

 

now i am starting to realise why the old owner sold car the car and why he hid the problem...

 

anyway what i am trying to get at is below:

 

my @BOOSTING@ problem that causes the car to stop pulling for a second when flooring it does seem to happen just before it goes into third

 

is this coincidence or could this box be the symptom of my hesistation? either way i need my boost solenoids reconnected to be sure but now i am thinking i was sold a car with a dieing gearbox

also what diagnostic problem is 15 flashes?

also there is no clunking or grinding sounds of any sort

cheers matey :-)

 

i am going to perform a gearbox diagnostic in an hour after i finish the house work.

When the lock up clutch operates to freeze the torque converter and make the drive totally direct it feels like a fifth gear being engaged. The revs drop again as the slip disappears just like when a gear change occurs.

ahh ok so that is one relief.... well now to find out why it hates changing into 3rd soon
