Sorry to drop what I'm sure is probably the hundredth 3 bars thread on here but my car has some specific symptoms I'm hoping someone will recognise.
So my car is an 04 roadster pretty basic standard spec, only has about 45k miles on the clock and seems like it was fairly well looked after by its previous owner.
The 3 bars & bleeping appear as soon as the ignition is live and continue after the engine starts which it does with no issues.
Manual mode is unusable however sliding into Automatic or Reverse clears the 3 bars and the A or R appears.
Unfortunately on 2 occasions over four weeks the car has gone to 3 bars when in Auto mode, fixed this once by cutting the ignition and restarting after 40 mins, the second time it appeared to work however went back to 3 bars after a couple of mins and had to call recovery to get it home.
Two things I've noticed are that when the bars appear in A the car continues to drive and shift gears normally until the car comes to a stop despite the bars however when the box returns to neutral it won't shift into first and take off, the engine just revs.
Secondly the rear reverse light sticks on and glows more intensely when the car is put in reverse - Previously just removed the bulb to continue using the car.
Thirdly this might be just be, but I swear the problem always manifests when driving uphill....
Have previously attempted to alleviate the problem by applying white lithium grease to the actuator however as an amateur I cant 100% assure it was performed correctly.
I'd be deeply grateful for any insight you can offer, I really love my Roadster but I've had a back issue so I'm not earning enough to fund extensive garage repairs. The real irony is the legs outstretched driving position of the Roadster suits my back problem perfectly.
Also if this is likely to require a professional repair and anyone knows a ballpark figure then let me know - on the verge of scrapping the car here.
