rover twincam rwd what gearbox

lt77 or r380 from an ldv/sherpa O series petrol.. or one from a diesel with the petrol bellhousing.. or one from a morgan if you saw wheeler dealers as that had the rover twin cam fitted.. that gearbox looked like an lt77 as well.. also you will need the inlet manifold from a 2.0 MPi landrover discovery as that has the throttle at the front. cheers ian.

Any rear wheel drive box could be used, just make an adaptor plate up. Ford type 9`s are fairly cheap and plentiful, or supra/celica, omega etc etc! get the cheapest 1 you can!! ;D

Or put the right oil in, apparently. I was going to try this on the SD1...

"Here is a radical solution to an unfriendly 5-speed gearbox. My Vitesse used to have a truly nasty gearbox. It baulked at will and was notchy to a fault. In fact it was very, very hard work. This was my last resort.
• During a routine gearbox oil level check, I noticed how dirty the lubricant had become so it was obvious it had to be flushed and changed. It had the recommended ATF which Rover had been forced to specify, because the gearbox was unreliable when filled with conventional lubricant.
• By coincidence, I had been told by an Ex-Mobil employee that Mobil 1 or Castrol RS at 0W40 or 5W40 viscosity were considered by the trade to be a better replacement than ATF in the Rover 5 speed box and gave a much improved performance.
• With the car on axle stands and the back wheels off the ground I drained the box and re-filled it with a flushing mixture of 2:1 white spirit and ATF (I did say radical and it was a last resort!).

• With the engine running at idle speed only, I put the car through all the gears and let the drive train run off-load for 5 to 10 minutes.
• Upon draining the flushing mixture I was amazed at the filthy color and state of the drained fluid. It was as black as ebony with lots of sediment!
• I repeated the above with a clean batch of mixture to flush out the residues. One can imagine the washing machine action inside the box allowed the solvent component to reach into every recess.
• The box was then refilled with 5W40 "Castrol RS" (0W40 "Mobil 1" is virtually the same and I have subsequently used both with no discernable difference).
• I then added a recommended dose of Molyslip Gearbox Treatment. This stuff comes in a tube-like applicator and is available from Halfords, etc.
• The transformation was miraculous. It has run for over 8 years without any of the original symptoms and is a total pleasure to use.
• The oil has been replaced twice in that period with Mobil 1 and the same Molyslip gearbox additive each time.
• As an experiment I used the leftover Molyslip treatment in the Vitesse rear axle differential.
• After thoroughly warming the axle with an electric fan heater I sucked out all the old lubricant with a large medical syringe and some flexible plastic tube. It was then refilled with fresh hypoid oil (as specified) and the mentioned Molyslip treatment.
• The rear axle differential was transformed. Taking both treatments into account, the whole drive train has been silky smooth ever since. So good in fact, I treated my Vdp axle to the same deal."

I don't think the ATF is an issue per se - I think that the method detailed above gets rid of the occasional "wrenching excalibur from the stone" feel of 2nd-3rd shifts. Which I know I've encountered plenty of times!
