Advise please!

I am having problems with selection of reverse gear.

When the engine is hot selecting 5th then reverse avoids / reduces grinding the gears - do they really all do this??

When the engine is cold - reversing out of the garage -
selecting reverse is ***** difficult - whatever gear is preselected before reverse.

Car is still under warranty so would like to get it sorted if it can be - (2000 5ltr with 20k miles)

What can I say 'they all do that'. I find that dropping it into fifth then into reverse works quite well. Otherwise just line it up and pull back hard and fast and it'll go in without any trouble.

yep... they all do it!! The difficulty in engaging reverse should go when the gear box is warm but the engaging 5th first is somthing we all do.

Even works for Griffiths. Reverse is much more forgiving if you select 5th first.

You've probably already thought of this but why not reverse the car in? - then you only need forward gears to get out! Otherwise select a gear, let the clutch up a mite, then try reverse

Actually I always use 4th then reverse - just seems easier to me

Personally I've never had a problem getting reverse and don't have to put it into 5th or any other gear first. It can graunch a small amount if you jam it into reverse too quickly or roughly. Certainly there is no difference between hot and cold.
If it is really dificult when cold I would expect it to be sorted under warranty.

I found either 3rd or 1st to be better.

The only reason for doing is that there is no syncro on reverse.

This has always been a feature of the T5 box, 5th before reverse is the rule unless you want embarrassing noises in public!

Here's another solution....

Why not just leave the car parked in reverse?

Someone tell me if I'm doing wrong here, coz I've been doing this for a couple of weeks!

yep, 1st or 3rd engaged first to avoid any crunch - Borg Warner box on mine. Was the same with my old S3 too.

Same here...... I don't need to select anything before reverse..... just being stationary, push clutch, wait a few seconds and ease it in (ooo err )

Correct, there is no syncro, but IIRC syncros are for changing gears when moving (ie: matching moving gears to other noving gears), so should not be a problem when stationary.....

I thought you weren't supposed to start a TVR with your clutch in,unless your starting your's in gear and reversing back on your starter!!!!.


Yeah.... tell me if starting the engine with the clutch down is a bad idea..... coz I do it every time!

Can't see how starting car with clutch down is bad - if anything it should be good because you are reducing the strain on the starter motor. It's only turning the engine over, not half the gearbox as well.

I'm a T5 stirrer too, and i always do the 5th->reverse technique. If it doesn't work, i let the clutch out in neutral then try again with the 5th-> reverse. Sorted.

Hey, even if it's not ideal, it's got to be better than "GRRRRRAAAUUUUNNNCCHHHHH" right?

Exactly..... always done it with new(er) cars to reduce load on the starter/battery etc, as you say. However, I *don't* do it with the old Triumph, as it puts unneeded load on the crank thrust washers right at the point when they are most vulnerable (no/minimal/cold oil)..... was suddenly worried that there might be something that would make doing it on the Chim a bad idea......

*phew*

I too was always warned about thrust washers etc - on early Chims the Rover box has an oil pump (don't know if T5 has or not?), so depressing clutch and starting is NOT a good idea, but its a balance on starter motor/battery strain - if indoors I don't depress clutch, outdoors cold nights, I probably would!

What you describe is entirely normal for TVR's and part of what makes them different.

Suggest that you pump the clutch pedal two or three times before engaging a gear, especially if the car has been parked for a few days. Then follow advice already given regarding the engaging of 1st/2nd then 5th before trying reverse.

A gearbox in a TVR with 300 bhp needs to be big and chunky. If you wanted low effort slick gear changes then you should have bought a Nissan Micra.

Which means that the time between you putting your foot on the clutch and all the inners to stop wurring is longer than something like a micra. All that putting it into a forward gear first does is use the syncromesh to stop the wurring so that it can go into reverse without gruanching.
Not something that I would worry about (and yes I have to do the 5th-reverse shuffle as well).

How does holding the clutch down in a car reduce the strain on the starter motor?.When the thrust bearing is pressed against the fingers of the clutch theres a lot of force against it,far more than just spinning the shaft going through the gear box.


The force excerted against the fingers isn't transmitted through to the engine though is it? it is just being used to move the clutch plate away from the flywheel, thus removing the revolving mass of the gearbox, however slight, from that of the engine? Or am I misunderstanding something?

Well, that's pretty much what i figured (and i think someone told me that once). Who knows?
