Can you tell me what grade oil & how much is needed to change the oil in my gearbox & transfer case in a 80 series manual as I've been told it could be running the wrong grade oil, as it is hard to sellect first & notchy when going to second & third or is this normal as I've never owned a landcruiser before. Cheers Dave.

Try Hd 75 grade and see what the result is,mine has done over 460,000 ks and no problem with the gear change. Also check you fuel usage and report back later
on this post.

Turnitup, There is some gearbox oil called vmx80.Works well on hard shift synchros.Put it in our troopy gearbox only and is good.Makes shifts smoother.We put 80w/90 gear oil in the transfer case.Good luck.

Try this lube guide from Castrol, it gives suitable oil and volume. Valvoline and Shell have similar features on their web sites.

Hi Turnitup,

We had the same problem with our 80series manual and at first we were told that it was the wrong oil, started running straight 80 grade oil and still no change. The gear changing got progressively worse so Toyota evenutally pulled the gear box out and found that the first, second and third mesh gears had worn with a lip on themm therefore catching shift change gear. They replaced all the sync gearing and also found that the ball and yolk on the clutch had also worn. Replaced the hole lot under warranty (160000ks on clock) Since then the vehicle changes smoothly and is totally different to drive, it is a dream to drive!

Turnitup,

No. We purchased our 94model second hand with 132000ks on the clock. Then 4mths after purchased, we noticed that it was sticky between changes 1, 2 & 3. This got prgressively worse as time wore on and was in and out of the workshop for a while because we kept saying that there was something wrong with it. Then after about 6mths of complaining, they decided to do something about it. By this time though, our 6mth warranty had run out. They found then that it was the clucth that they replaced earlier was faulty. They then proceeded to do replace this and give us our vehicle back. I took it back to them the next day with the gear worse between 2 & 3, it was actually crunching during change (it gave a new meaning to a crash box). They then proceeded to pull out the gear box and found what the cause was. Toyota were very good to us on this occassion as they said it would take them 3 days to repair it. After the third day they rang us up to come and pick up their demo vehicle as it was going to take them 3 weeks to get the parts from overseas. Didn't mind running around town in a brand new camry, but it did put a dampener on our week-end getaways. In total we had had the vehicle almost 11mths (10 driving), clock up almost another 30000k, and they said not to worry about the bill, it is a warranty job.

Correct oil is Mobil 424 fluid.
Caltex brand is Textran.
Wack this in and you will never look back.

Gday
General consensus on 80scool.org is an oil called Castrol vmx-m (m is for mitsubishi...they had a similar problem) it is a 75/80 i believe and as i said, most people on that list are using it with their notchy boxes, and have tried many others b4 hand. Thats not to say all the above oils will not work better than what you have at the moment....just that...well you know about free advice.
