Ratio 1.1
I restored my old One Ten from 1983 and put new gearboxes in. I bravely decided to use a ratio 1.1 on the LT77 and on the 200Tdi, which are built in the car.
My hope was to get the car more quiet with reduced revs.
Conclusion:
With this ratio, the 200 Tdi drives like a car with a 4-speed manual gearbox up to 100 km/h. The 5th gear of the manual gearbox is only usable from ca. 80 km/h with tuned engine, not before. But I never missed anything in the first 4 gears. Remember, this car is not a racecar :-) In the 5th gear the number of revs is lowered so much, that even 120 km/h are pleasantly quiet possible. Moderate tuning is necessary but then the car is absolutely comfortable.
My result is very positive. That was a good decision.

The Ashcoft Lt230 with ATB
I recently purchased the rebuilt Lt230 with the ATB center diff. I was quite pleased with being able to email my questions and concerns Directly with Mr. Ashcroft. He directed me to exactly what model and what features I needed, The payment process and shipping was expertly coordinated and I received my parts much quicker than I anticipated! All the way to California, USA! As for the unit itself, looks like new and it functions absolutely perfect. This LT 230 was installed in an 94 Range Rover Classic LWB. I replaced the Borg Warner. I had read the LT230 would be noisy compared to the Borg Warner. This is quieter than my old 200,000 MILE BW, by a wide margin.I recommend Ashcroft Transmissions very highly.
The experience in general was actually pleasant, and informative. The product looked great, and was crated well. I needed nothing extra to make my swap. Mr. Ashcroft even helped me with my speedometer swapping questions. If you just need to replace your old unit or are swapping to another type, This is the place to go, you won't be disappointed. The 5 star rating is as high as I could rate, they are definitely a 10 star establishment.
