[QUOTE="zamzainal, post: 397737, member: 19238"] Yup Zeedo, You're absolutely right! The main culprit is the [COLOR="Red"][U]oil seal of the oil cooler [/U][/COLOR]from the gear box to the so call heat exchanger, the oil seal cost only RM 80, but the labour quite extensive since the whole system have to be drainage and flush, and not to mention the new gear oil, gasket, seal and coolant. [U][B]Btw, i come across this posting BMWClubMalaysia.com Forums > The BMW Range > 3 Series > E46 [B]water spare tank,[/B] posted by [B]machaplai[/B] 6-28-2009[/B][/U] " problem just solved yesterday...[B].cost me rm1965[/B]...i changed radiotor cooler,automatic oil cooler,termostat,gearbox flush,etc.........god damm coz ATF mix with water oledi..flush gearbox use 14 bottle of atf...inside the radiator cooler also mix with atf....at tuesday i need to change the atf again.." [U][B][I]"[B]Quote:Originally Posted by jinooi erm, how did ATF (auto transmission fluid) get into you radiator?[/B][/I][/B][/U] the culprit should be the gearbox oil cooler when it leaked. it is recommended to change it around 80-90K. the gearbox oil is cool by running through the gearbox oil cooler interconnecting with the coolant (this is what the mechanic told me)" [U][B]reply by [B]jarance[/B][/B][/U] [I]Quote:Originally Posted by jinooi [I]wait a minute... but still this doesn't explain why the TS found ATF in his radiator coolant... not unless the tranny housing is cracked? the ATF in the gearbox, is it for cooling or just lubrication only? and when we install an transmission cooler, is it going to cool the ATF or the radiator coolant? i'm getting a bit confused...[/I][/I] [B]The ATF is for the hydraulic power for changing the automatic gears in the tranny. It is driven by a hydraulic pump in the gearbox. When ATF or oil is compress, it will generate heat hence you need to cool the ATF oil. The ATF oil is cool via 2 pipes which circulate the oil from the pump to the ATF cooler and back to the oil sump. The radiator serve 2 functions. 1.
