Thread: 6sp versus 8sp transmission

You should drive both, as it comes down to which is better value to you.

TR is a simple update on earlier models to run the later response.

Thanks Mike - I'd forgotten that - now to insert that bloody IID Tool into the new car - once I email Canada for the changeover code (free). Love their service!

Get an adapter lead, 2 into 1 and use that.
Keeps the tool from getting caught up and leaves an OBD port in stock location for servicing.

Or better still, one of these…

When I was in the market for my car I had 70k and that put me only up to MY11 if I talked them down. I went to Mackay land Rover to test drive and the salesmen said no way mate. I asked why not. He said the 6 speed box ( in my price range) was the best box in the world. Unfortunately the 8 is even better!! He told me.. Don't ever drive the 8 it'll ruin life with the 6, that was in 2013 and I still have not driven the 8 speed.

The fact that D4's, or most LR's for that matter, don't hold their value is a bad thing for those who bought them new ... but an absolute bargain for those picking them up second hand.
The vehicles are packed full of features and are pretty cost effective as long as you are able to do most of the maintenance or repairs on the vehicle yourself.
I nearly went across to the dark side and even started to look at Landcruisers!!
The Landcruiser is a very capable vehicle, just like LR, but after looking around at them it becomes very evident that they are highly over-rated and ridiculously over-priced.
I cannot believe the prices they are asking for LC's and particularly for those with very high kilometers.
There seems to be a complete disconnect with reality out there in the 4x4 market place.
The laws of 'supply & demand' just don't seem to apply when it comes to new 4x4 buyers and Toyotas.

For the same reasons, put an EGT gauge in the D4 2.7L 6 speed, and have never got above 650 in worst case scenarios - at the same time coolant never got above 107 - and yes at those levels I did quickly slow down a little just in case, but have stopped worrying for the D4 - completely different animal to the overworked D2. And yes I have always been approaching paranoid to ensure the coolant system remains in excellent working order.

Now do I put an EGT gauge in for the new 3L 8 speed?

Yes .. I'm much the same.
I've got EGT, Transmission and Head temp gauges plus a boost pressure guage in the D2 and will find it difficult to go to a D4 3.0L without .. so I'll probably just put the EGT and Transmissions gauges back in the new one .. just for my own sanity.

I'm tending to lean towards the 8 speed as, at the end of the day, my main concern for going to a 3.0L D4 is it's towing ability. (legally)
If it wasn't for the fact that the Disco 2 TD5 can't legally tow the 3T van I probably wouldn't even change over ... I've been very happy with the TD5 and I know it inside out .. which means a lot when you're operating remotely.

Interesting .. I wasn't aware of that.

Will this tool display EGT Mike?
I looked through their gauges list I didn't see it.
