Im portuguese from lisbon, i buy a range rover 1995 4.6 hse and the manual mode of the gearbox only works in the lower gears, in the higher only works the sport mode. It´s normal?

height sensors may have failed or air bags faulty but this should produce a fail code.

the fuel filter is located under the vehicle , below drivers foot well , you will have to remove the plastic shield that connects to the gearbox to get to the filter

a 1999 landrover Range Rover is in constant 4 wheel drive. the only change you can make is high or low range and this is handled through the gear shift selection.

I don't know the solution and I don't want $$ but have you checked all your mode switches? It sounds like you have selected hill climbing mode or something similar.

The HSE designation refers to a Sport Edition 'Rover, not a higher-priced premium edition.
Changing fuel grades can harm an engine that doesn't have computer controlled valve timing.
Symptoms include a pronounced, fast "knock" (usually when you go from 93 to 87 octane) and using a fuel with a higher octane rating than the vehicle requires (example: 93 versus 87) sends unburned fuel into the emissions system and catalytic converter. This puts stress on the emissions system. For some vehicles, a rotten egg smell or a pop when the fuel burns off in the catalytic converter coming from the tailpipe signals use of higher than needed octane gas.

HOPE THIS HELPS! Don't forget to rate!

dont f with it

No the coolant radiator is a sealed system, oil and water do not mix; as far as I am aware manual gearboxes do not have coolers.

If you have oil in your coolant water this will be an engine problem. Check the engine oil is not frothy and caramel coloured.

If your gear box oil is is a brown colour or dirty looking, this is due to water ingress, either through the breather hose or seals, try changing the fluid. If you can check the seals and breaher hose.

Suggest you get a owners manual and Haynes or workshop manual.
There are plenty of free files on line, do a search on Google, Alltheweb, Lycos, etc

so does my exwife but,Iwould look at your idle control valve

Do a serch on Google for RAVE. This is the land rover workshop manuals. The owner manuals are included.

This new five-passenger premium sport-utility vehicle filled a price gap between Land Rover's LR3 and its ultraluxury Range Rover models. In fact, the all-wheel-drive Range Rover Sport was smaller than either, designed to compete with "high-performance" SUVs such as V8 versions of the BMW X5 and Porsche Cayenne, as well as Cadillac's SRX. Based on the seven-passenger LR3's body-on-frame structure, the Range Rover Sport came as the HSE model with a 300-horsepower, 4.4-liter V8, and in Supercharged trim with a 390-horsepower, 4.2-liter V8. Both engines were sourced from Jaguar, which was owned by Land Rover's parent company, Ford. A six-speed automatic with manual shift gate was the sole transmission. All-wheel drive with low-range gearing was standard, and included Land Rover's Terrain Response system, designed to automatically tailor AWD performance to specific off-road conditions. Also included were a height-adjustable air suspension, antiskid/traction control, and antilock four-wheel disc brakes. The Supercharged model came with 20-inch wheels and Brembo-brand front brakes. On the HSE, 19-inch tires were standard and 20-inch optional. Both models contained front side airbags, head-protecting curtain side airbags, and a navigation system. Standard on the Supercharged model and available for the HSE were wood interior trim, heated seats, and Land Rover's Dynamic Response suspension system, designed to counteract body lean in turns. Satellite radio, wireless cell phone link capability, and rear DVD entertainment were options. Adaptive cruise control was available for the Supercharged edition.
