Leaving your car in reverse gear while rolling down a hill

Hey guys,

Earlier today i turned into a steep hill street and I realised that it was the wrong street so I put it in reverse gear to pull out of the street but then a taxi came up behind me so I couldn't get out of the street. So I went down the hill but after going down about 50 metres I realised I still left it in reverse gear while my foot was pressed down on the clutch pedal. I only realised I left it in reverse gear when I heard that winding noise reverse gear makes so I immediately put it in neutral. 

I was wondering if this could damage the gearbox or any transmission system or anything else on the car. I tested reverse gear straight after and it still seemed fine but I just wanted to make sure.

thanks

I'm sure 50m won't cause a problem, but potential issue is that the oil pump is running backwards so no oil pressure in the motor for that time. 
 

Seen as his foot was on the clutch and im guessing the car must have been running (seen as it was being driven prior to this) for a start would not have been an issue.

I'd like to here your reasoning for this Duncan....how does the oil pump run backwards?  This  - to my thinking - means that the motor was running backwards??

Only way I can think of this happening is if you are rolling backwards down a steep hill while its in say 3rd gear but the motor is switched off??? And if its switched off, no bang or boost so no oil pressure would not be a bad thing given the duration. But willing to learn.

Nope, not a thing.

Sorry forgot to mention that the front of the car was facing down the hill . I wasn't going down the hill backwards like I was reversing down the hill if u can get the picture

Haha, The engine runs clockwise no matter what gear you are in... Oil pressure would not be effected at all.

If you had of taking your foot off the clutch then best case scenario the engine stalls and you come to a abrupt stop... worst case something may have broken from the shock load..

But you didn't so nothing to worry about at all.

    • Didnt realise RB's had more then 1 head.
    • I'm normally copping my own abuse from neglecting my daily drivers. "Those suspension bushes will last a bit more", "Don't worry about the oil leak, just keep topping it up". The project cars I'm always doing things slowly on them as I'm wanting them to be done better, and neater, and nicer. Luckily I don't have to deal with 18 year old Matt's "Learning to wire" stuff in the project cars. And there's only one piece of wiring I'm displeased about in the Landcruiser, and it's about to be cut out... However, the box loads of parts that have been going through this place lately for the Landcruiser... Brake pads Brake Rotors Full handbrake overhaul Wheel Bearings Seals Swivel hubs Steering Boxes Half the suspension joints Shocks Air bags (Ones to go in the rear springs for towing) Water pump Timing kit Lower timing case Harmonic Balancer Radiator Lots of other little seals and shits Gas struts for the bonnet New power window switches And god knows what else I've forgotten... Ha ha ha I have my fingers crossed the pinion seals don't start leaking on the diffs, that the transfer case doesn't leak, and the gearbox input shaft doesn't leak, nor the rear main seal. As they're about the only seals I haven't replaced in the driveline! I'm seriously eyeing off buying new caliper rebuild kits front and rear brake calipers... I'll probably recheck all the valve clearances soon too, and hopefully, it should be all good and sweet to haul some long distance trips again!
    • Every time I pull my 3x gauges out of the console and see the crack-addict way that I did the wiring, and I just can't bring myself to tear it all apart and "make it nice", because it is currently working. In fact, the last time I was in there I probably made it worse.
    • The best part is when you own the car long enough that you look back and find your OWN ham fisted amateur shit!
    • The annoying part about neglect, is when you start to replace one thing, and find ten more broken things. Ham fisted monkey repairs you normally only find out about when trying to do something unrelated! Ha ha   Neglect you can kind of anticipate the huge costs to fix it all. Ham fistedness is normally a shock the first time your work on a new old car, as everything "looked" good before.
