changing shifter what's the best fluid for my T5

[Roland69]

I thought I should change the fluid while I have the shifter out but what should I replace it with. I know ATF is what it calls for but should I go synthetic....what brand do you guy's reccomend. Should I take the fill plug out or just put 2.6 litres in.

i just stick with ATF. Thats what Ford wanted in them so that what I run.

 

[Roland69]

no synthetic's

 

[86bluecobra]

No i haven't put a synthetic in my tranny.

Just plain old Dex III, and stay away from Synchromesh in a T5.

I have been using Redline for several years now.

Next change however, I will use Mobil 1. Mobil 1 is easier to find here in Seatown.

Just make sure it is an appropriate ATF.

[Roland69]

so any DEX 111 is what I want

I run D4 personally. If you drive the car in a cold climate (cold morning starts), the synthetic might be nice. I use it for 110*F ambient temps in the summer (opposite extreme).

You are not going to go too far wrong, so dont sweat it too much.

Good luck.

 

[Roland69]

the normal temp here in the summer is 18*C it might get up to 30*C during the day but normally 25-+.

 

[Roland69]

oh and what's the difference in DEX III and IIII

 

[HISSIN50]

Seems to me that the two choices are Mercon and Mercon V. We use Mercon.

 

[Roland69]

I'm lost when it comes to tranny fluid.

 

[86bluecobra]

I guess the difference between the 2 is temp. Basically viscosity. Just like in motor oil's. Redline has always had a good name but regular old atf has worked for me.

 

[HISSIN50]

I'm lost. The difference between Mercon and MV is application. MV is a blend that's designed with electronic tranny calibration in mind.

And it seems to me that the Dexron stuff is GM fluid.

None of that really matters.

 

[Roland69]

so should I run a mercon is that what they call for or does it even really matter

 

[86bluecobra]

run the ATF the manual calls for. This way your not going wrong

 

[srothfuss]

Go to the parts store and get some Dex3/Mercon (Mercron?) The store brand ATF will be blended for both GM applications and Ford Applications. Just don't get the stuff for Chrysler vehicles, which is ATF+4 IIRC. Either synthetic or regular. That is pretty much all there is to it.

Personally, I run the regular stuff because I change it often.

 

[maverick0716]

Redline D4. I've been using it for a couple years, and it seems good.

 

[5spd GT]

I run Royal Purple Dex/Mer. III synthetic.

I had always used regualar tranny fluid until this last change when I put Royal Purple in. I had never had any tranny grinding problems until after the RP was in...but it was after a hard trip at the track. I never had the problem before with hard shifts...

I doubt it matters much...and the Redline D4 is good stuff from what I understand.

I always head that the T-5 works best with ATF. I put Aamco Mercon V sythetic blend in my rebuilt tranny. It shifts great. You can get it at AutoZone.
