Lt230t

I have a 1995 D-90 and just lost high range. I've been told I can use a "Q" box, but would have to install my tail section( for the speedometer). Does this sound correct? I would use a "T" box but can't find one. Tim

I believe they are the same Tcase as the ones on the Disco I's or at least for the same year. If that's the case then you can get a Tcase from this place where I got the shifter with DIFF LOCK.

There was a thread here before about Ashcroft Trans in the UK. The site might give you some idea as to what I mentioned hereinabove regarding the D1's having the same Tcase. Here it is!

Ashcroft Transmissions

If they are the same....check out the guy that's selling parts for Defenders and Disco I in the FOR SALE section of this forum, I believe he has a Tcase for a Disco I. Assuming that it works, you might get a good deal.

Hope this helps.

TIM,

I talked to you today. I have a T box and Q Box. In 1996 a LT230Q revised transfer gearbox replaced the LT230T unit. The later ones carried the name LT230Q. They have smaller (weaker gears) but a thicker case. The thicker case and smaller gears helped keep the unit quiet hence the Q that follows the name. Around 1981 LT230s were made. They were a straight roller bearing design and carried the name LT230R. From 1981 to 1985 they remained the same. After 85 they went to a straight roller bearing design with an intermediate shaft. In 89 dog tooth changes and it remained the same until 94. In 1995 they started to drill the input gear for better oil circulation. 1995 and 1996 Discos had these sought after t-cases.

94 up D1'S WERE EQUIPPED WITH THE WELL LOVED VEHICLE SPEED SENSOR. You MAY need to remove the LT-230?s electronic speedometer unit if your LT-230 came from a Discovery and replace it with the mechanical unit if your Defender is so equipped. You will also have to remove the neutral switch if you use a used unit from an auto.
