I've been reading your recommendations on fluid for the MTX75. I've got a Focus diesel over here in the UK which is suffering from intermittent heavy engagement of 3rd gear, it can need quite a shove to get it to go in, but it never crunches. I had the fluid changed at the last service at a Ford dealer, which improved things for a short time but it's now back to normal. Over here, Ford used to recommend an M2C 186A spec fluid, but they changed in the last year or two to specifying the same fluid as the IB5, M2C 200C, which turns out to be a 75W90 gear oil.
I'm planning to change the fluid again in a couple of months to something else, but I don't think I'm able to get the Ford honey here in the UK - do you reckon Royal Purple Synchomax is an acceptable alternative, or did I ought to seek out something else? Comma and Millers both do an MT75 oil, would I be better off using that? Apparently it's more or less a 75W90 oil too.
Thanks very much in advance, and sorry to trouble you with a question you've probably been asked hundreds of times before!

Ford Synthetic Manual Transmission fluid is the top pick. Royal Purple is a close second.

The cable end that wears out is on the tranny side of the cable. As far as I'm aware... the only part that really wears on the shifter (and doesn't get replaced by the steeda) is the white plastic bushing for the side-to-side movement. I just ordered a new one from Bill J.
I'll take a look at that in the morning, thanks - I was considering installing a Steeda short shift in the near future anyway, so I'll have a look at replacing the cable end when I do it to be on the safe side.

FWIW..we here in Michigan have a bit of a cold spell right now so I left our own car with and MTX75 trans (and Honey in the kogbox) out last night to do a cold shift/engagement test this morning.OK the car is an X Type Jag but the trans is an MTX75.This morning around 5.30AM it was 13 Degrees F here...Started the car,slid easy into gear,drove off ...no shift problems,no blocking or stiff shifts etc.About a mile or so up the raod the temp was colder(from the outside tep registered in the car)It was 10 Degrees F.
So to all those who say honey doesn't shift well in the cold...BUNK!!! If you still have stiff shifts with honey chances are you have tight shift forks or other issues withing the trans but it's not the lube.

To add further confusion, Royal Purple say that for M2C 200-C and for XT-M5-QS spec I need to use their SAE 10W/40 engine oil, not Synchromax, and not their Max-Gear 75W/90 either. Help!

By the way my owners manual from Ford for my SVT also says use ATF-DO NOT USE ATF

it didnt say synthetic anywhere on it but will it work?

Just don't use ATF. Diesel 15w-40 is a better alternative over ATF. Amsoil and Royal Purple both make MTX fluids that are full synth and cost about $8/qt.

A close 2nd- Royal Purple Syncromax
3-Fully Synthetic Diesel motor oil 15w40
Amsoil is also a popular option-they do make Syn. diesel motor oil
Do not buy regular diesel motor oil, I put RP Syncromax in my CSVT it is an immediate noticable difference do yourself a favor LISTEN to Terry most good tranny advice that you get here will be regergitated Terry knowledge
