I have a 5spd auto

[jakewaze]

Hi
My VN S has a 5spd auto. I never really took any notice of the gears but today i was on my way home on tonkin hwy and decided to try out what gears the car does at what speed. So at the lights I took off slowly all the way to 100, at about 20kmh it went to 2nd, then about 45kmh it went to 3rd, then about 60kmh it went to 4th and then about 85-90kmh it went to 5th. Is this rare cos I always thought commodores were a 4spd???
And don't tell me it is a 4spd, with the exhaust i've got I can tell when it changes gear. Also at 100k's i was doin about 1600rpm

No, it doesnt.

My mums VS cruises at 100ks at bout 2000rpm i think and mine is a few hundred less which would also explain a 5th gear. Also i'll try get a sound recording of it goin through the gears tonight

Our VN and VT, both cruise at a bees dick over 1500 rpm. Remember Tyre sizes, diff ratios etc will change your speedo reading, and your RPM at certain speeds.

Photos of the gearbox and any model numbers off it. Also your shifter as it should now have read P,R,N,D,4,3,2,1

Well i asure you it is changing 5 times, I'm suprised too. One of the previous owners may have had done somethin done to it in the past 20yrs or somethin. I am goin to do it again tonight a few times to make sure

5 speed if you include reverse maybe...

Do it lots more
Doing it with an even throttle response, dont back it off, put it down if you get what I mean. If you lift your foot it can shift, then when reapplied it will down shift, which could be tricking you to think theres an extra gear.

Ive still got my left testicle on it not being a 5speed auto.

nope it actually the torque converter locking at 85kmh thats what you think is 5th.

And don't tell me it is a 4spd

It is a 4spd.

Torque converter locks up over 80kph and drops the revs for highway economy.

Was about to say Torque convertor locking creates the illusion of 5th... but the last 2 posts beat me to it.

[Fun_Bucket]

Does he still think it's a 5spd?

[jakewaze]

ok well u cant blame me for thinking it was a 5th gear, the revs drop about 500rpm when it happens. anyway what is actually happening then

[delcowizzid]

the ecu trips a solinoid at a certian speed that makes a clutch in the torque converter lock solid for better economy at cruise.

and thats where babies come from.

so, are you now enlightened to the magical ways of the gearbox

[jakewaze]

thx guys, thought i had rare car for a while lol

[centy]

mate i was offered a 5sp buy a guy who rekons he brought it as a 5 speed.
Moving the shift it was a four speed just like the rest, the reason he thought it was a 5 speed is the shift kit and slightly higher then standard stall converter.
He got real shitty when it was pointed out to him so went and check and i was right which pissed him of more as i would not pay as much for a 4spd that had been flogged.
So you are not alone.
