Can anyone help with this gearbox fault. After having fixed more than enough faults on this car having bought it a few months ago I still have one that is in need of fixing.
When cold the gearbox changes up and down very erratically. Sometimes it loses gear completely until almost stationary before it re-engages. Very often it will get stuck in 2 or 3 rd and the revs go up but it won't change. When hot and engine is switched off then back on again it behaves normally.
When the gearbox has the above problem the engine light comes on with two fault codes 0715 speed sensor circuit A and 0730 incorrect gear ratio.
The service history says the auto fluid was changed about 15k miles ago. It is possible it is low. How do I check? If it is low there must be a leak?
I believe you can check the fluid level with STAR or using a bespoke dipstick. Does anyone have the exact dimensions of this dip stick so that I can make my own?
Any help would be appreciated. Mr Spanner
