IM-32-FK Posted January 6, 2017 Share Posted January 6, 2017 (edited) 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 Edited January 6, 2017 by IM-32-FK Link to comment https://www.sau.com.au/forums/topic/468493-leaving-your-car-in-reverse-gear-while-rolling-down-a-hill/ Share on other sites More sharing options...
Duncan Posted January 7, 2017 Share Posted January 7, 2017 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. 1 Link to comment https://www.sau.com.au/forums/topic/468493-leaving-your-car-in-reverse-gear-while-rolling-down-a-hill/#findComment-7803126 Share on other sites More sharing options...

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.

Duncan Posted January 7, 2017 Share Posted January 7, 2017 Yeah like Callan said the car must have been running and clutch in for this case. I was thinking steep hill, in gear, clutch out, motor not running Link to comment https://www.sau.com.au/forums/topic/468493-leaving-your-car-in-reverse-gear-while-rolling-down-a-hill/#findComment-7803142 Share on other sites More sharing options...

dyl33 Posted January 7, 2017 Share Posted January 7, 2017 If your foot was on the clutch and pressed in, no gear is selected. Your just riding the clutch. If you were going forward down the hill in reverse and let the clutch out you may have a problem.

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.
