Auto transmission questions

[OPASEN]

To all you autos out there I have a question.

I dont know if this is normal maybe you can tell me.

In snow mode gear changes are smooth and acceleration is decresed to aid in traction.

In normal mode there is more power but the gear changes are rougher. eg 1st to 2nd is abit clunkyer.

In power mode the gear change is severe with heaps more power occasionaly causeing it to chirp.

My guess is that it is trying to simulate a manual slaming into second especialy when on boost.

I have discussed this with my mechanic and he asures me that ists all normal. I dont know wether to belive him or not. I have already had to change the box thanks to the pevious owner never changeing the transmission fluid. This is now in a box that has done 40k kms. I asked if the bands needed tightening. I was told no..... Am I getting ****ed around or is all this just normal.

P.s can these boxes handle being driven like a manual. I have heaps of mates saying I should drive it that way but I dont want to **** anything up. I dont feel like haveing to buy another gearbox....

Any help is good help thanx guys......

in snow mode the first gear is disengaged.

when my auto changes gears you can not feel the change unless im flogging it.

but even then it would be very rare that i feel the change other than the kick back from power into 2nd.

i drive my auto like a manual and have for the last 25000kms.

when i drive it like a manual (change gears myself) mine most of the time just fishes into 2nd.

but after all i put mine through my gear changes are soft.

maybe in your replacement box someone has installed a shift kit which would make changes rougher and faster.

power mode maxes out rev range but still shouldnt be rough.

id be checking to see if valve body has been modified.

my 2cents worth

I just keep thrashing mine, I'd be happy if it blew up.. make me do the manual conversion much quicker

Your changes can be rough if the base timing is too low, or is being dropped due to pinging

[OPASEN]

Thankx guys Ill get it checkd....

[OPASEN]

yeah thanx guys but i dont think its from pinging the cars all in good nick everything else has been looked after and the cars bog stock so i dont think its been modifyed at all....

As slide said, someone may have put a shift kit in your replacement box that you dont know about. I had the auto (which has since been changed to manual cos thats what I prefer), and I used to drive it like a manual with no problems at all.

I have seen some autos drive a bit funny if they are low on fluid, they sort of wind up and then smack into gear all of a sudden.... make sure it has enough in it. If all else fails, drive it like a manual and if it breaks, I still have my auto box in the shed for sale...

[OPASEN]

thanx man but given that the box was just replased it should still have all the oil in it. the old box used to whine so loud half of newcastle could hear it. this new one is quiet but still abit funny. to be quite honest i really hope it doesnt break it cost me $1800 for the last one.

[Slide]

could have bought a 5 speed for 1800

[OPASEN]

Yeah I know but there was an autobox available right there and then. so i just went for it. regreting it just a little....... but what can do.....

there is a diagnostic mode that you can run for your automatic transmission, is you do a search you should find the procedure on how to do it .. that will tell you if everything is running ok..

Another thing to do is see if there is another member with an auto that lives close to you and see if you can get a drive to see if its any different..

I've heard of auto beeing picked up (second hand) for as little as $200 - most wreckers just can't get rid of them.

Check out the Group buy section to see if anyone in your area has purchased and installed a shift kit, that will give you a good idea of what quick shifts should be like. The nissan box is a bit quicker than a holden or ford slush box, but your description sound a bit harsh for a standard box.

Personally I like the auto (after the shift kit was installed), catch up with some other autos and ask for a ride to compare yours and theirs.
