Any reason not to double clutch?

Started double clutching this weekend, it's definitely easier on the 1-2 shift, is there any reason not to do this?

I do it some when its really cold and the fluid needs to warm up. What transmission fluid are you running? I dont think it is nesccesary.

I'm not having any synchro issues, the gearbox has 10k miles on it, I was thinking more as a preventative measure.

I used to practice shifting without the clutch in my 109. Match road speed and engine RPM and it would shift right in withiut the clutch. I also used to practice double clutching with the 109, the fire engine I drive at work requires double clutching in all gears.

a good tranny fluid is a good precaution, there is alot more going in your gearbox that would benefit more from a high quality fluid than can be prevented by double clutching.

Mike Green of West Coast British recommends 1 qt Castrol Syntec 5/50 and the rest D4 Redline. I have that mix and it's noticeable better. And my 3rd gear syncro has been gone for 40K miles...

I'm using MTF in the T-case, D4 and Syntec in my L77 which calls for ATF in the manual.

Well now, where's the part about heel and toe? After all, one needs a foot for the brakes, since using the e-brake is a no no in the Land of Rover...

Just an FYI, but in my opinion, you really shouldn't be using MTL in the Transfer Case. The Transfer Case calls for a GL-5 rated gear oil (75W90), also known as EP or Extreme pressure (I say this because I think this is how it is actually refered to in the owners manual) gear oils. MTL is a GL-4 rated oil, designed specifically for transmissions, that are shifted regularly and at speed. GL-5 (EP) gear oils are bad for the syncronizers because one of their additives (the name escapes me at the moment) reacts poorly with the brass in the snycronizer rings.

Also as an FYI, most of you probably know, but Land Rover put out a service Bulletin in late '97 changing the R-380 lubricant recomendation from ATF to a product called MTF-94. It is produced by Caltex of Australia, and its specifications are nearly identical to RedLine's MTL. Here is a link...

http://www.caltex.com.au/products_oil_detail.asp?id=107

If anyone cares, I actually run RedLine's 75W140 GL-5 Gear oils in both Differentials, the transfer case, and the Swivel Balls, and MTL in the R-380 Gearboxs of both my Defender and my Discovery. I've been very happy with the combination.
