Mitsubishi ck4/ck2 tranni

Postby bOOsTmaN » July 20th, 2007, 11:36 pm

i have a couple questions

what happens when you go from neutral into drive while givin car gas?

gearing down... does this reduce the life of trani? you kno the selector has 3,2,1...
letting the engine slow down the car

well i "heard" since the transmission is an electronic transmission whatever you do it goes tru the computer and then engages the trani.

Eg. you rev out in neutral and then pull down into drive
(At this point the computer handles everything to precision so that you wouldn't damage the trani.

finally i have heard a rumour that say your doing 180km and you need to make an emergency stop and you pull gear selector into 1. NOTHING will happen. CAR will gear down normally. is this tru?

if you do it with a nissan b14... your trani will fall apart.

:D :D :D Nah soldier the B14 tranny wouldn't fall apart.I try to kill one for ah year,doing the same thing...reving till 7000rpm and dropping it in drive with yuh foot still on the accelarator.Gearing down from drive at 110km/h straight down to first.The brain has a fail safe to protect the engine over revving so it needs to slow down to a safe speed before engaging second,then the same thing for first gear etc.
What happens is 1)the valve body starts to deteriorate(lose pressure)
The clutches start to slip.When last yuh chnge yuh trans. oil?Yuh seein any filings in the old oil?

with an automatic tranny, no damage would occur by switchin gears manually, cuz if u leave the shifter on a gear for too long, the tranny would automatically upshift or downshift according to ur rpm. and yeah, if youre doing 180 and shift into first, nothing would happen, beacuse of the fail safe mechanism hottstuff was tlkin about

If you want to rip I suggest a gear box.
In the Ck's I don't think when u go from neutral to drive while on the gas the gears would delay to engage! I know for the CVT's the tranny computer will delay the tranny from engaging untill the rpm drops.

I never tried the down-shift to 1 from high speed ~180km

I know about down-shifting from high revs, low speed during solodex and the response is immediate

shifting between up and down 1 and 2

several times i shifted from N to D while giving slight gas ~1200 rpm, there was a definite jerk

So in other words downshifting to slow down will slowly kill my tranny?

like from D to 3 to slow down the car

Alyuh mad yes. Never tried it but there are things called gear ratios. Can your transmission reach 180km/h in 1st gear?


Easy on the transmission there sb64.

what happens when you go from neutral into drive while givin car gas?

I am no expert on transmission internals , but from my info they have clutches ( or clutch packs ) that are designed for slippage ie at idle speed for when you shift fron N to D or vice versa. They are not intended to handle slippage at high engine speeds such as in a manual gearbox clutch so when you shift from N to D or D to N at speeds above idle you will be reducing life of these clutches ( due ot more wear at high speeds) resulting in transmission repairs.

Their are failsafe mechanisms via engine / trannt ECUs to handle over revving but these are just supplementary if you continue moving from D to L at high speeds this will shorten life of transmission, some owners manual suggest you use these in emergency situations only and the ECU will handle the downshifting , engine speed etc but if this is done often well engine and transmission life will be shortened.
I cant comment on B14 but I know parts for my car is expensive so I rearly do these things and if I do it is not done from 180k, maybe at less than 160k.

As I said before, in evertything there are gear ratios.



You want an example? From a standstill, put the selector in L. Drive it and see how far and how fast you will go. What I have realised with the CVT is that you can go from D to Ds at almost any speed. I have geared down from D into Ds several times before when I needed the car to decelerate rapidly.

With a conventional transmission, it's different. Just like with a gear box, the gears in a conventional transmission will rev out and you would have no choice but to shift the selector manually from 1,2,(some cars 3) then D so when decelerating and gearing, if your vehicle could have only acheived 80-90 Kmph in 2, then why the hell would you gear down from 3 to 2 at 140Kmph?
