Gearbox Problem!!!!!!!!!!!!!!!

[ken yeang]

Cooler prevent the ATF being cooked. Broken-down ATF wont offer GB internals protection.........and eventually failure of the GB itself.
Kereta potong has plenty of coolers to choose from. Invest on one and install it for a peace of mind.

of course, driving style matter. Driving at a relaxed cruising speed isnt as damaging to BG compared to 180km/hr highway runs.

Not to forget changing the atf on schedule.....hhahahhahah

True, atf wont last forever...and has a shelf life too.

Well, most people remembers to change engine oil but most of the time forgets the atf. Atf can forget because the change intervals are longer.....

 

[ken yeang]

or just make it a "routine"........change atf whenever changing engine oil.......
GB sure smoot-smoot....

Wah! like that very very heavy maintenance dy.....if OCI 5k, atf 20k, means additional 3 times atf change and some atf cost so much more than EO....

Prevention is better than cure, they say....

Anyway, me think TS problem is beyond ATF stuff. Let's hope if the GB is repairable.

Why not? Worse case is full overhaul......lol

Hey guys thank you for all the reply. So sorry for the late reply, been busy...
any good workshop i can get my GB checked out??

thats my rule of thumb for my 1.6 auto satria as well...

rm25/bottle of proton atf (1litre bottle) usually just need 2-3litre unless if open the oilpan and change filter as well....

Cheap and possibly temporary solution : Flush the gearbox and change the ATF filter and use Lubeguard additives.

Probably permanent solution : Rebuild the GB

I've tried Lucas ATF additive, Lubegard red.. and it didn't work.

Finally I tried TransX before I rebuild the gearbox..it worked.

My problem was that the car wasn't engaging reverse gear, and when driving forward..it won't shift up.. a bottle of TransX, last year..and now..I just change ATF as usual and the car is fine.

For a RM40 bottle of liquid.. versus RM1.5k to rebuild.. not bad trying.

Tumpang thread as I have gb problems too. I want to ask you guys, right now my car during highway cruising 4th it will suddenly drop to 3rd gear, normally where there's a slope, something like the engine braking when coming down from Genting. However recently it occurring more often and yesterday my trip from JB I stopped at almost all rest stops to restart the engine. But even so after 10 kms or so the problem will surface again. What I want to ask is has anyone faced this problem before and is it something other than the gearbox? Appreciate any advice.

What car and what type of GB? Sounds like protection mode though. What speed were you going at?

 

[humongousgravy]

Hi car is perdana v6. Normally happens around 100 and going downhill

 

[Izso]

Going downhill at 100km/h? Wah.. big balls. Personally I think you should start with the basics, change the ATF oil and filter (use the proper spec oil, not D3 or D4 or whatever. If I'm not mistaken it uses SPIII so consider a good SPIII like Mitsubishi Diaqueen SPIII or something better. Then consider an ATF cooler. The Perdana has a fundamental weakness in its gearbox cooling design. Gearbox oil RM120+-, ATF filter RM80+- and halfcut ATF cooler RM100+-

If all of this fails to solve the problem consider a well known additive like Lubeguard platinum. RM100 give or take for the additive.

If even that fails to solve the problem then you'll need to consult a GB specialist and that'll be the most expensive option. RM1000++

 

[vr2turbo]

GB rebuild can be RM3k plus.......1k is cheap dy. Even half cut now should cost around RM3k if not mistaken

 

[humongousgravy]

Not exactly downhill Genting, but down a slope as per those on N highway. I have done all those you stated. ALL cooler, change my Atf religiously every 20k km or less, atf filter changed every 40k, but still. I was wondering if it is the TCU being the culprit here? Or perhaps it's just the spirit of the manual gearbox calling out to me...

Ya I also use SP3 ATF, also tried the Rock oil Multi ATF and then now switched to Proton SP3. Then the problem became more obvious

 

[KenDiriwan]

Would you care to share the grade of those oil rather than just brand ?

ATF SPIII mah! not engine oil.....

 

[humongousgravy]

I'm not sure what's their grade, but the Rock oil one was fully synthetic
