can u put r380 gearbox in 200tdi

[bodgeitjo]

hi guys and girls, just wondering what i would need to change / add to change from lt77 to r380. i have heard that the 300 tdi is a stronger box is this true?. thanx in advance.             jo

IIRC it was designed to handle more torque, so I guess it is stronger but more than that it's a much nicer box even when worn out.  IIRC it still has recognised weak spots though but if I could get one I'd fit it.

As far as i know the lt uses cable speedo and the 380 is electronic. Other than that i think its a straght swap.

Yes pretty much straight swap. Make sure it is a Discovery gearbox and even the bell housing bolt pattern is the same....

...however, you will need to change over the speedo sender, R380 one is electronic as already noted. When you look at both LT77 and R380 side by side you will see that they both have all the mounting bolt holes so you can fit the LT77 mounting to the R380 and reuse your original gearbox cross member.

I've swapped LT77 into a Disco behind a 300Tdi and put an R380 behind a 200Tdi also in a Discovery. PM me if you want any help etc :)

You will also need to change the hand brake cable if using the drum on the R380 box as they have different fittings to the LT77.

Good point, what year is the Disco?chances are it's got the electronic sender on the LH chassis rail anyway, so it's just a matter of wing it up.  AFAIK the pulse/timing is the same on the R380 sender as the LT77 one.

cheers guys thanx for your responses so far. hand brake no probs got both types in garage. its a 94 disco so not sure about wireing.

Yeah you're right. I changed over the handbrake and speedo bits when the box was on the floor. I links up with the handbrake lever that is already there, that end of things is the same.

Mine has an R380 I beleive. Gearleaver gaiter is a bit of a bodge though.

I'm pretty sure you have an electronic speedo then.

Don't forget to change the gear knob as reverse is on the opposite side.

I wondered about this aswell, so is just a straight swap?

Drop old gearbox and transfer box swap in R380 and transfer box with new handbrake drum etc, and wire up speedo?

Is it that simple  :?

[wizard]

yep that about it. Mines been in for a few years now. Still got the original gear knob though...

As an anti-theft device?

[stuntman]

Okay so just to make REALLY sure the mechanical side is just a straight lt box out R380 with 200 tdi handbrake in? The rest is just wiring up etc.

What about the transfer box? is the 300 series the same as a 200 series etc? I'm really sorry for asking for idiots guides to this but I'm also in the position that my gearbox and transfer box are on the way out in my 200

Thanks in advance everyone
