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.

      A 1.5 way is a 2 way. It is just a 2 way with a less aggressive ramp on overrun.

      The ABS and/or TCS being missing/broken will not cause the engine to misbehave. It just casues CEL to come on and annoy you. The CEL is useless if it is always on, so you have to do the things you have to do to get rid of it, so it can be useful. Being a Stag ECU, then yes, it will not expect TCS to be present. But it will expect ABS to be present and working. You will need to either make the ABS CU talk to the ECU (don't ask me what that will take on an NA R34), and make sure the hardware is working....or, you just need to blank it out in Nistune. Do not persist with the stock ECU. You will just have problems. Gte it Nistuned. Start from there. DO YOU HAVE A BOOST SENSOR? The ECU's boost sensor that it. It is connected to the loom at the rear of the coil cover. Usually rides on the firewall on an R34, but is usually bolted down to a bracket along with all the other crap at the back of the coil cover when a Neo is dropped into another car. If you do not have it, the ECU will shit the bed. So, do you have one?

      So sadly the fuel pump etc was not it. The pump and filter is new and it is still cutting around 4000 rpm. A read something about ABS/TCS (engine is from stagea and ECU too so no TCS) and i dont know for 100% that my car has ABS. It has ABS "cube" in engine bay but i dont think it works(or at least from my braking experience). Can be something like that?  I will be driving the car next week to Nistune tuner to properly see what is wrong...

      the Tomei LSD fluid with lsd kit. frustrated that it was shaking the car to crap and affecting everything else negatively, I pulled the diff last night, and removed the lsd carrier, could not find anything wrong, however it seem to be 100 locked up acceleration, and deacceleration, wondering if they sent me a 2 way not a 1.5??  either way I installed the stock open carrier back in place. test drove everything smooth as butter again. no shake, shutter, random, what felt like clutch slip and grab or drive shaft play, etc. something differently wrong in side the lsd. I might bother taking it apart (if possible) to figure out what's going on inside this carrier, as bought too long ago to return.  only draw back is its back to a one wheel wonder.
