I have a TF with a difficult gear change . It's always OK when the engine is cold but after apprx 20 miles it starts to get notchy and difficult to select gears but not impossible. Any ideas .

Problem is I’m an old guy without a useable garage and a TF that lives under a cover on a nice driveway !
I agree that this is not the ideal time-of-year for working "Al-Fresco", but as the car is stored in damp conditions, Chris T's point is all-the-more valid. Brake fluid suffers the same hygroscopic effects of course. In the case of brake fluid, it does not get hot and release water (as steam!!) until you are braking hard, perhaps at the bottom of a long hill or downramp from and elevated Motorway?? Not a good place to realise that you should have changed fluids earlier!

I changed gearbox oil on my 20-year-old TF and the previously difficult 3rd to 4th, and 5th back down to 4th gearchanges became smooth-as-silk.
My gearbox oil was not low (I measured the volume which drained-out), but the old oil was pretty dark in colour:
Tableware Drinkware Dishware Cup Serveware

Changing the oil was an easy DIY job: a longish drive to get the oil hot, raise rear wheels on axle stands or ramps, remove drain plug (3/8" square socket driver fits nicely), then leave to drain into a 4-pint empty milk bottle or similar and go and have lunch.
Re-filling is a slow job unless you have a pump. I used a length of plastic tube and funnel from above:

Vehicle Motor vehicle Hood Automotive design Automotive lighting

Whilst underneath the gearbox, worth checking that the gaiters around the cables are not like mine used to be:
Gas Motor vehicle Auto part Machine Electrical wiring


Again, it was an easy DIY job to change these.
Happy motoring next Spring!

Thats exactly the same way that I fill the gearbox, your underside is lovely and clean. Mine is always a bit oily because the nearside drive shaft seal leaks, changed it twice but still leaks. I notice that your boot lid cables seem to be in what looks like a piece of hose pipe, or do my eyes deceive me? Regards. D4KGP.

Yes its a problem when we get older (73) as to whether we can carry on sliding under cars in or out of a garage. Just had major abdominal surgery but too many jobs to do to throw in the towel yet. Not ready for the Grim Reaper;). Regards. D4KGP.

You will often find that the gear selector mechanism (under the console/leather gaitor) has some 'slack' in it. Take a look at this and see if anything needs tightening up.

Also remember that the heater pipes run through the 'transmission tunnel' so heat can have an effect on gear change, but not in the same way that you would ordinarily expect with other cars....

Good luck.

I suspect that this is "as delivered/as built" by Rover. There is certainly no record of any work in that area in any of the comprehensive service records, and the P.O does not seemed to have been a DIY'er.

If you & others reading this have "naked" cables in that area, I am guessing that someone has had problems with the loom in that area, and it has been exposed to do repairs.

The only other possibility that the dealer (MGF Centre Wolverhampton) did this very neat modification to prevent or at least reduce the probability of problems in that area. I would be interested to know what other TF owners with similar dated (2002) TFs.
