Hi all.

Looking at the official checklist it shows only to "Check MT transmission oil level every 4 years or 24,000 miles". No sign of replacement. No sign of annual inspection. How could they possibly have got that wrong?

IMO: Service sheets are here to cheaply maintain your vehicle while under warranty. Manufacturers want to make sure it will last through warranty and want to show how maintenance is not expensive. I plan to keep the car for longer than warranty lasts, so do more frequent and proper maintenance.
 
Hmm, my first thoughts were, given the gearbox (which incorporates the front diff.) will work it's oil just as hard as the transfer box and the rear diff work their oils, then surely Toyota wouldn't allow it's GR gearbox oil to remain in situ for the life of the car. Yet they instruct to change both the trans box/rear diff. oils every 24K/4 years.

Why could this be?

Either it's a mistake on the checklist sheet or there's a significant mechanical difference inside?

Correct me if I'm wrong but the only thing that comes to mind is I'm thinking that both the trans box and the rear diff will have a bevel gear to turn the drive through 90 degrees but the gearbox unit won't? - Or maybe the trans box and rear diff are very compact units which each only use 0.5 litre of oil and can get a bit too hot when tracked?


Thoughts?

I will give you a nod as that's a bloody good point. But unfortunately I haven't a clue what you are talking about, so will just let Toyota service my car knowing that if things go wrong I have the backing of their 10 year warranty.
 
Cheers Mark, I appreciate your nod. So much so that I'd like to offer you one in return. :giggle:
