Today’s modern cars, and especially those with automatic gearboxes, have electronic controls in the gearbox themselves.
They communicate with other parts of the car via a ‘Controller Area Networker’ or as it is more commonly known a – CAN Bus.
Automatic gearbox diagnostics can be difficult. It is important that all logged fault codes are able to be read from diagnostics performed on the vehicle.
This will in some cases fail to give you the cause of the problem. However this is where VMTP Midlands Ltd specialist diagnostic equipment and years of experience are combined to give a clearer diagnosis of your automatic gearbox issues.
Really simple faults, including a poor battery, can cause significant problems with an automatic gearbox.
It is therefore essential that the correct diagnostic equipment is available for automatic cars to ensure that your car can be professionally and accurately diagnosed.

Requirements of automatic gearbox diagnostics:
- Drive line evaluation undertaken if possible
- Fault codes need to be correctly read
- The fault codes need to be cleared
- Second drive line evaluation to see which fault codes re-appear
- Fault codes to be correctly read for analysis
- Checking of the fluid level and state of the oil
- The automatic gearbox is then re-calibrated and/or re-programmed if required
The issues that can occur is that some aftermarket diagnostic equipment can’t read all the codes, which can lead to an incorrect diagnosis of the fault in the automatic gearbox.
Additionally if all the codes have not been read they cannot all be cleared.
On top of that, very few pieces of aftermarket diagnostic equipment can re-calibrate/re-programme the automatic gearbox – many now require re-programming by going online to the vehicle manufacturers systems.
Why choose us to carry out your automatic gearbox diagnostics?
VMTP Midlands Ltd continue to invest heavily in our automatic gearbox diagnostics equipment, so that we can keep pace with the rapidly changing vehicle technology and increasingly sophisticated automatic transmissions appearing in the market place.
VMTP Midlands Ltd have purchased a number of the original manufacturer’s equipment and therefore their ability. This means we can carry out most of the diagnostic requirements ‘in house’.

They were able to reassure me and leave my mind at peace which I couldn’t thank them enough for especially with the experience I had at a previous garage.
I will and would recommend them to anyone if they have a transmission or gearbox issue, as I genuinely thought my car was never going to run again after being without out for nearly a month prior to them receiving it.
I can’t thank them enough and will take my car back there in a heartbeat but with the fix they provided I’d be extremely surprised if an issue were to reoccur anytime soon. Massive massive thanks to Lee and Nigel for the service!

Absolutely cannot rate the team at VMTP highly enough.
I picked up a T5 transporter with an automatic box. Very quickly started showing signs of being very poorly. Not engaging gears and over revving.
Not only did VMTP sort the absolute lot! (on a gearbox that parts are bloody hard to get hold of no less) they sorted the recovery of the van for me, and kept everything as reasonable as possible price wise given the complexity of the fix. With constant updates to boot.
If you have an issue, don’t hesitate to go and see these guys. Absolutely phenomenal service from start to finish.

If I could give a higher star rating I would.
I honestly cannot thank Lee and his team enough for the sheer amount of work they did to my mom’s car to get her back in the road. They went above and beyond to replace a clutch on a VW UP, when nobody else would. Thankfully she’s back driving and everything is fine.
If ever I’m in a position to recommend them to anyone I will (but promise it won’t be for a VW UP next time)
