TR3650 nochy shifting??

[mineralrob]

Just curious what tranny fluid everyone runs and what can make the TR3650 a tad smoother. Mine isnt bad but i've heard stories of people switching to diffrent fluids which make it alittle smoother. Its mainly notchy beetween 1-2 but all of the other gears are smooth as butter. My car has 20k and still has the factory fluid in it(if fluid will even make a diffrence). I've gotten a million diffrent answers that go both ways as far as changing to synthetics etc. Or will these trannys always be notchy and dont worry about it,lol. Any input??

Thanks
