Auto box magic fluid or advise
Having some issues with the Trerrano auto.
Nothing too major and seems to be improving slightly itself
(It's Reluctant to change ito top at 50-60 and low load, then hunts a bit whehn spped reached)
Just wondering whether it's worth trying the Auto box eqivenlant of Redex as a cure all or whetre theres anyuthing really to service on the box
that's going to make any difference?

Not found a manic solution for autos
The one I had in a Galaxy VR6, so a VW box was rebuilt at great cost then went again a few years later, cause was a worn hydraulic body, looks like a
shallow sump with a maze in it and there were also questions about the ECU.
I drained the fluid and put new in a couple of times, smoothed things out for a while.

Most modern conventional automatics require a fluid change and filter clean/change at around the 60,000 mile mark. Modern auto boxes are generally
nowhere near as robust as the old 1950's and 1960's yankee boxes.
I don't know what make of transmission is fitted to the Teranno but I would guess a JATCO box (JATCO were once part of Nissan), I
don't know anything of the JATCO RWD boxes but FWD JATCO boxes made in the late 1990's and early 2000's were a bit
problematic due to cracked valve bodies and sludge problems.
A fluid change and filter & sump clean might cure things but getting the fluid level correct is absolutely essential, on the tranverse JATCO
boxes this requires connecting the car to diagnostic equipment warming the gearbox and with car on a level surface putting the selector lever
through all the gear positions several times.

As said, change the fuid first then after a week change it again as it doesn't all drain out in the first instance. This usually cures many auto
box problems.

OK Good I'll try an box oil change.
Interestinly I "thought" the box oil looked a bit high if anything when giving it a cursory going over.
I wonder if this in itself could cause a problem?

If you get a smell of burnt toast off the fluid or it looks black/brown then the gearbox is on its last legs.
Root of the problems with modern autoboxes is for environmental reasons the friction materials used in the transmission were changed and are not as
tolerant to overheating and lack of lubrication.
