2013 v40 d3 automatic gearbox replacement advice
 

Hi all,

I own a 2013 volvo d3 auto which has a tf80-sd gearbox. Recently it has started shunting really badly when I put it into drive so I tried a tcm update and and a gearbox oil change which hasn't helped cure the problem.

I have resigned myself to having to change the gearbox but I'm a bit lost as to which gearbox will be compatible. The part number of mine is 1285186 on the red plate and there are a few on ebay with different part numbers so I was hoping someone could shed some light on whether it has to be an exact match or will a slightly different one will do the job? Also will it make a difference if the one I buy comes from a AWD car? Any help is much appreciated.

Thanks.

That is a bit drastic getting a new gearbox , this is a known problem with a fix , it could be simply an adaption test drive ... Or it could be some internal seal rings need replacing with modified parts . Your dealer knows all about what to do .

It is most likely the valve body - a good transmission specialist will be able to advise. Remember the transmission is manufactured by Aisin, a Toyota-owned company, and used in Toyota, Lexus, Mazda and a host of other brands. There is a good body of knowledge to fix these but make sure you approach one with a solid track record.

It will be less risk than buying a second hand one off a web site with no recourse.

It is not the valve body it is exactly what i described above ... Valve body problems on newer volvos from about 2006 are zero ...

This is one of the very few known circumstances where the Volvo procedure is to open up the gearbox and replace/upgrade parts - i.e. if the diagnosis route leads them to this then you can have reasonable confidence that it will work.

Thanks for the input. I will book it in with Volvo and see if they can give me a clear idea of what may need replacing and hope it's not too big of a bill!

If Volvo do come back with the conclusion that a new gearbox is required, then I would suggest your only alternative is a gearbox specialist.

Automatic gearboxes need fluid at pressure and electronics to work - they can only really be diagnosed whilst still in the car - unlike manual boxes. Hence you need to take it somewhere who has done a few before and can diagnose it.

A new box from Volvo might not be as expensive as you fear and will come with a good warranty.

It's a good fix for that sympton though .. but labour heavy of course but minimal dismantling ...
