I have been doing some research and need some input or feed back from you.
I have an inter scout with a 392 v8 and a 727 auto I was wondering if the lt230 t/case would fit on the 727 with the rover 727 tail housing, if so is the lt230 strong enough.
Also what years would have the best ratios?
Or a good link to a spec sheet on the years and ratios.

Eric

a 230 is definetly strong enough. i am pretty sure that you could get the two to mate together using the method you said, and it would be pretty cool to see.

the best LT230 to find would be one that came behind a truck that had a 727, as this would have the 1.02?:1 high range and the same 3.3:1 low as all of the other 230s.

sounds like a cool project. what are you going to do about needing an offset rear axle?

Hey Eric I'm glad you made it out of the Binderbulletin. Yes I go by Robert Mann over on the BB and I'm the LR MOD here on POR.

There is a rumor that the Rover 727 is a IH case with an adapter to the Rover engine!

Adam is correct in that a Range Rover with a 3-speed auto 727 came with the LT230. Not many people (none that I know of) have put in a Torque flight 727 in place of the ZFHP44 that is the typical auto that come in our vehicles. Not sure if they fit though. I would *guess* yes and that it would be a no problem swap.

The RRs with the LT230 have a 1.003 High Range and all LT230s regardless of what they came out of have a 3.32 low. Optional Maxi-drive low range gears can be fitted to change that to a 4.34. Most commonly you will see LT230s with a close to 1.2 high range. They differ dramatically from case to case between anything from a 1.923 to a 1.206 to a 1.211 to a 1.22. A 1.410 and 1.667 are also available but slightly more rare.

The LT230 make the Atlas T-case look small. They are that burly to give you an idea.

LT230s come with what is called a Box S/N that is located on the main body of the case. This number tells a lot about the box. The prefix you will want to look for for a RR LT230 will be one of the following: 14D, 15D, 20D, 26D, 27D, or 30D. All others are most likely out of a Disco or D90.

Oh yeah forgot to add a link for you. This one is pretty good.

Yes I thought it was 3.3 to 1 and that’s a lot better then the 2.04 to 1 I have now. I have not looked at the t/case yet and I’m not sure how much the off set would be, I don’t have the $$ to change the rear diff so as the its my D/D I cant drive it with tail shaft vibrations.

Old scout
I have heard the same but now one can confirm it. Maybe I will find out.

Thanks for the link. I will call the guy who has the box to find out the number.

Here is the whole shop manual on the T/C

Don't know if this will matter or not for fitting into a scout but the 727 is clocked slightly (can't remeber which way) in the RR when used with the LT230.

Yea, and I heard the reason for that was that the valve body is to wide (on the left) to fit "properly" between the frame rails...Which makes me wonder how Coop is dropping TH400's in Rover chassis?

I dunno'...Is the TF727 wider than the TH400?

(can you see I'm already thinking about stage 2? :flipoff2:

The size is an issue. Mark's makes adaptors for the TH400 and 4L80E to the LT230 but I haven't gotten my head around how I would fit all that into a rover. The NV4500 will fit ok other that having to rework the tunnel and seat base a little. The other one I've been looking at is the TH350 or the TH700R4. Ashcroft used to make an adaptor for the TH350 to the LT230 but stopped due to lack of demand. Cooper has made one TH700R4 but he said it is very long, a guy I've talked to that made his own adaptor and fit a 700 to an LT230 in a RR said the same thing (the adaptor needs to be around 7 to 9 inches long for the LT230 front output housing to clear the 700 valve body). I think it would be ok in a 100in or longer rig but I don't know about the 90. Maybe if you used a 4.3 V6 and moved it all foward it would workout.

Just some of my odd transmission thoughts.

I have an NV4500 and a TH700R4 sitting here and one or both of them will get used at somepoint. For now the 90 is getting a ZF just to get it on it's feet.

eric, the LT230 is a good alternative to the D20 sitting on there!

damned if i don't miss my old traveler :( it was an '80 w/ the 3.3L t-diesel, T18 (close), and had the good dana 300 xfer case. was open on both ends, but compared to prices on rover stuff, i would be happy as a lark to rebuild those 44's now.

the scout was in too good of condition (and all original) or i would have kept it and bolted a few things onto this rangie of mine.

cheers,

I seem to recall that I saw a page where someone had used one of the 4.3 adapters from ashcroft in a 1st generation rangie. They dumped a vortec in there, and I believe that they ran with the gm tranny. I will try and dig up the page.

I seem to remember that to and for some reason *remember* that they said there was not much gain of any sort. Can't imagine why one would go to all of that trouble for a v6 unless you plan on removing the majority of the weight on your vehicle, which is kinda hard to do on rovers as they are so damn heavy. Where is all of the weight?

The vortec V6 has a better torque curve and much more of it. Near 280lbs and if memory serves around 1600~1800 rpm then flat. Also better fuel management and more HP with better mileage, around 19 in a rover. Very easily modified as well.

Found this last night while searching my two 80-gig hard drives full of images.

Hey is that the base to a mop bucket?

well, DUH! :flipoff2:
