Gear issues :( ,D1 300tdi 1998

Hi there,
I have been having some gear issues with my D1. Have already been told that I would have to have it rebuilt at some point, but was trying to postpone it (it's about 2300$ here).
The symptoms are:
1) It starts in 2nd gear
2) When it switches from 3rd to 4th at about 80-90Km/h and about 2700rpm, the rpm will drop sharply to 1600-1700 which makes it lose power.
3) It sometimes takes a second or two from putting it in D until something actually happens. This happens less since the gear oil was changed (recently).
All of the above happen only in high gear, the low gear seems to function right.

Any thoughts? Is a gear rebuild the only solution or is there anything else that can be done?

Thank you!

Ok let's take you issue's one by one.
1. If the engine starts with the gearbox selector in any position other P or N is an indication of the selector inhibitor switch or its electrical circuit is faulty have you checked,

The selector has been faulty for month. It is bypassed and I am careful not to start in gear. Needs to be replaced, they are expensive the buggers.

2. Ok so your travelling at around 55-60mph and the engine revs drop and the vehicle loose power, what happens next? I assume you have a petrol engine. It the vehicles servicing up todate? importantly fuel and air filter, clean crank case breather.

Its a diesel 300tdi, automatic. Once it switches from 3rd to 4th the rpm drop way down to 1500-1700. This is off course too low to maintain power so it will barely go for a while until it reaches 2000rpm or so. Then it is ok again, cruising at 100kmh / 2200rpm approx.

3. Do you mean that there's a short delay in drive being taken up or it doesn't doesn't creep forward any more when the brake is released, is the engine idle speed around 650-700 rpm?

No, I meant that once you put it into D (drive) and hit the pedal it sometimes takes 2-3 seconds before it starts moving.

And I take it you you say high and low gear you don't mean the transfers box high and low range gear ratios.

Yes. All this only happens in the high range. (other than the switch being faulty at all times off course)

Just three questions I'm afraid, as I don't have a working crystal ball, neither do I try at guessing, unless I know I it be right

Hi, The car was just serviced and all oils/fluids replaced. This is at a LR specialist whom I trust. I don't have a comfi place to do these things so I usually take it there. Anyway, the problems have been there for a while, long before this service and have actually improved a bit afterwards (the delay in function is much better).
I am most intrigued (and concerned) by the dramatic drop in rpm between 3rd and 4th. The vehicle becomes sluggish and only recovers when it reaches 2000 again. Any thoughts on that?

Ok so I take it your Land Rover specialist doesn't have the skills available to deal with your vehicles issues.

I'm actually happy with his skills so far. He has solved some other issues nicely. Wrt the gear he says it is on its way out and that I should drive it until it absolutely needs to be rebuilt. I wanted a 2nd opinion, hence this post.

The engine rpm dropping and recovering, if u have a 3.9, could be... but then maybe not as simple as a loose connection on the coil top, or an iffy coil, or even an iffy immobiliser (spider) cutting out and then in, or any thing else ignition related, have you have difficulty in starting the engine at all?

It's a 300tdi as the header says. Normally when it switched from 3rd to 4th gear it would drop from say 2700-2900 rpm to 2000ish. Now it drops at once to 1600ish which is too low. This on flat open road. It will then slowly gain speed and rpm until its ok again.
