Good day tsikoters, meron akong GLS Sport '05 with 13,500km ODO. This week napansin ko na meron irritating sound when shifting to 3rd gear naririnig ko lang ito kapag nakababa ang window, pero kapag naka AC window closed di mo maririnig. It goes like this (1st gear then when i reached 1500rpm shift to 2nd gear, then 1500rpm shift to 3rd gear- during this period kapag nagrelease ka ng clutch dahan dahan kasabay sa timpla ng accelerator pedal meron ako naririnig na ting-ting-ting-ting..... sounds sa makina, kapag sa 2nd gear meron din kaso mas matagal ang irriitating sounds sa 3rd gear pero kapag tumaas na ang rpm ng mga 2k rpm wala na cya. Pero kapag ang pag shift ko is hataw mode like (1st gear 2000 rpm or up then shift to 2nd when i reached 2K rpm shift to 3rd gear timpla ang clutch wala ka naman maririnig. kapag lang 1500rpm ka nagshift chaka ka may maririnig. Meron na po ba naka encounter ng problem na to. To all adventure owner paki try naman po na open window kayo then shift kayo lagi sa 1500rpm kung may irritating sound din kayo na maririnig. Merry Xmas to all of you!!!

I think! medyo mababa ang rpm na binibigay nyo sa ganung gear... sabi nyo pag hataw wala eh... May naririnig ako na gandin din try nyo 1stgear tpos release clucth at konting konting gas lang maririnig mo sya.. IMO, normal eto sa diesel engine.

Likot, Arvic,
I notice such strange sounds too emanating from the power train when I have "alanganin" shifts and low RPM gear changes or idle speed crawls. 1.5k RPM, as Arvic mentioned, is definitely a low RPM to upshift on flat road accelerations.
My observation is such strange sounds are telling how the diesel engine-to-transmission (tranny) ratios of Adventures work. The power train is configured to be load-bearing, meaning as people carrier.
Try this: when on medium to heavy load, with the same shifting habits at low RPM, does the sound occur? Have you heard the sound only when on light load (i.e., solo ka driving or with just one pax)?
Also, when the upshift is made, at what RPM are you "catching" the shift and picking it up?
There is undue "tension" in the power train when shifts are not made and caught up at the right RPM at certain acceleration conditions. This could lead to premature wear of parts in the power train, particularly transmission-related parts (e.g., release bearings, diaphragm springs, or the clutch disc itself.
My driving habit in smooth accelerating is I upshift only at no less than 2k RPM and catch the higher gear at no less than 1.5k RPM. I don't pick up on speed (or depress the accelerator pedal hard) if at below 2k RPM. During fast acceleration or during "perky" driving, I bring the RPM up to 3k before upshifting. The catch up RPM to the higher gear then also is higher than 1.5k RPM. Of course shifting RPM ranges are variable depending on load, road grade, and how much quick acceleration is needed.
Max torque of the Adventure is achieved at 2.5k RPM. As a rule of thumb, upshift only when or near max torque on flat road accelerations, beyond 2.5k RPM pa nga kung pa-salida or paakyat ang grade ng kalye.
Hope this helps.
Holiday cheers!
Albert

December 22nd, 2005 10:01 AM #5parang chirping sounds ba? Parang meron ako minsan naririnig kapag shifting at very low RPM. when already in gear, i can usually keep at a 1500-1700RPM and not hear this problem (with opened window).
hirapan siya sa 1500RPM siguro sa shifting. taasan mo at baka magkaron ka rin ng clatter sound sa clutch later on (see my other thread) - can't say for certain that is what will happen pero maigi na maging maingat. i moved up my shifting to 2000RPM (+/-200) - dati I did shifts even below 1500RPM. Use 2500RPM when need to pull hard.
Meron ako tina-try ngayon... shift from 3rd to 5th on a little over 2500RPM and catching it at mid between 1500-2000RPM. Bad ko noh?Last edited by RafRaf; December 22nd, 2005 at 10:41 AM.

December 23rd, 2005 03:43 AM #7ako umaabot sa 4,700rpm kaya inaabot ko maximum speed. for 5 years,nothing really bad happened except sa fuel consumptions. BTW.nice meeting you boss arvic!
