Auto Tranny Acting Werid

[sxc33]

Hey all, i have notice the auto box behaving a bit odd lately. And by lately, the last month, month and a half or so.

After i start up, i am on a highway doing 100 in a few minutes. It is holding revs at 2900rpm at 100 klms, then after a certain amount of time, it settles back to 2650 odd where it always has.

On colder days, it seems to take ages to find that final 'gear ratio' for lack of a better word. But when i start her up and get on the highway later on in the day when it has warmed up a bit it settles to 2650rpm quite suddenly.

Is this normal? Has the cold affected anyone else's slush boxes at all? I put a shift kit thru the auto last sat, flushed the fluid etc, but it still seems to do it.

Cheers,

Chris

So if i flush the lot out and replace with fully synthetic, would that make a difference at all?

When i put the shift kit in, i only drained and replaced with the normal rubbish.

I am planning on an upgraded 3000rpm torque convertor soonish, so i might do it then

when you replace the torque converter you'll get a majority of the oil out anyway. try running some 95LE in it, its used in falcons an has the synthetic additive already in it.

Its fine.

Cheers guys.

I have come across a 20 litre drum of fully synthetic stuff, so when the convertor gets done, it'll cop the full treatment.

Thanks again,

Chris

My car has done allegedly 64000 KMs, about 7000 KMs ago I serviced my auto tranny with Castrol Transmax Z... meant to be one of the best fully synthetic oils out there for autos.

I know that the oil in question is castrol, not sure what it is exactly. Fingers crossed its this one your refering to lol
