R33 Gtst Auto Box (jatco Re4ro1a) Review?

[R33TOM]

sorry for hi-jacking the thread but do you guys normally drive with overdrive on or off?

and whats the difference?

i know on highway if your crusing at 100/110 it will engage the overdrive gear, but just generally driving around town going 60 - 70 do you have overdrive on?

[GTR_STEALTH]

Generally if im just cruising around i drive with o/d on.

If im planning to give it a bit of boot, then i'll switch it off and maybe drop to second to get the revs right up.....

Ive a r33 with auto for nearly 5 years now, no problems at all, and im not easy on it. I control manually when the shifts happen, but every now and then ill let the computer do it. I am also running an aftermarket ECU (motec M48) and have no problems with line pressures or shift points. It is a FOUR speed box (o/drive being the 4th gear), with a lock up torque converter. I NEVER have over drive switched on unless im travelling over 80k's. All the autochanging in and out at around the 70'k mark is not good on clutch packs.

[**JaR**]

yeah. you really shouldnt use o/d unless your going over 80k's

[Modena]

I find that above 40km/h with OD off it revs harder... so i have it on always.

[LiQuid IcE]

yeah I use to drive with it on always because it revved lower, but after some research found that even though it rev's higher its not wasting any more petrol, and you use alot less throttle to pik-up

I turn O/D on when I'm hitting about 70kph

Did a search and found what I was looking for...

Definately a 3spd with an overdrive. the RB25 auto gearbox has its own ecu as well doesnt it?

[b1ancardi]

strange, because with the overdrive on VLs, I drive with it on (pwr button sticking out) since it doesnt really come into effect until you go over 70 anyway.

I only have it off if I'm going up hills or have a heavy load
