That's a-whole-nother issue. If someone really cares about the machinery, yes, you're potentially "loading" bearing pressure on the engine to some extent.

The rings only create compression when moving through the compression stroke and the chamber will lose that pressure once the engine stops, but still there's some unplanned load on valve gear and the potential for any rocking and motion of the car (say while being trailered or just being parked in gear every day and allowed to move that half inch downhill till the parking brake and the drivetrain take up the load.)

These are tiny moments of load and wear without oil pressure, but still not in the design of the system. The engine has to take a much worse load for the first rotation of the crank during a cold start after oil has drained and lost pressure in the gallery, but that's designed into the operation of the engine, and unavoidable (unless you get an accusump or the like.)

I don't think any engine manufacturer wants the valve gear or the gearbox gears to be meshed and moving without the engine developing oil pressure.

Of course you see people using 1st gear or maybe reverse as a "safety" for parking (and you see some folks wrench on the parking brake as if trying to hold back time itself, even when parking on a level surface) and you don't necessarily see those engines go "bang" as a consequence, but you do see failures on the track and wonder why one engine fails and another lasts -- I think the cumulative effect of each form of abuse takes its toll and contributes to mechanical failures.

 

Did I just read that if I shut down my ZR with parking brake set, and gear box in reverse, that I've meaningfully increased the odds of engine failure on the track?

Is that what I read?

 

Personally - I've never had a problem with my handbrake up and the car in neutral.

I've always been told to do it that way, Too much stress on the tranny.

Back in the day, Buddy had remote start on his 5 spd '85 Celica GT-S - Never had an issue.

 

Maybe that's what you read, but that's not what I wrote. : )

 

Ok.

 

I have never not left one in gear and never had a single issue, regardless of what type of vehicle it was. I set the brake first so that the pressure is on the brake, not the gearbox, but there is no way I would park my car on a surface that was less than perfectly flat and trust the brakes to hold it. Whatever small amount of wear it might put on the gearbox pales compared to having it roll off and crashing into something (or someONE) should the brakes slip or fail.

 

I had the same thought and figured it would be possible with the manual now because the car actually knows what gear the shift level is in with the active rev matching. So I would think these sensors could be applied to remote start, to make sure that if it was attempted the shifter has to be in neutral before the remote start is activated.

 

Your avatar says "end gun free zones." If someone advocates guns as the solution to gun violence, I'm not going to be able to convince them that parking brakes are safe.

 

So you think that a manual transmission has gears that are so fragile that when they are sitting at rest with even a few hundred pounds of pressure on them, they will wear out? Even though the gearsets are designed to handle thousands of pounds of pressure? Repeatedly?

Sorry but tranny's have been used this way since the beginning of time. If there was one single ounce of truth to it, the engineers that design them would have warnings and instructions in every owners manual about why not to do it. They certainly wouldn't have designed the C6 to REQUIRE the tranny left in reverse when you shut it off.

I don't mean to be harsh here but if it makes you feel better to make sure your tranny is left in neutral, you go right ahead. I've never blown a motor or a tranny on the street or the track and I have been using 1st gear as a parking brake for 50 years. There is just no evidence to support your theory.

 

You must have never owned a manual transmission C5 and parked on a slight incline?

GM recommends that you park the c7 in gear so maybe the gearbox was designed for it?

As far as all those different work around a to add remote start to a manual transmission car they all "could" fail. Here in the land of lawsuits that's the last thing any car manufacture Is going to want to deal with.

 

*headdesk*

(1) You do know people have been leaving parked cars in gear for a hundred years without this happening? Or else you do have pictures of disassembled gearboxes showing this kind of damage?

(2) You do know GM expressly recommended that early C6s be parked in reverse to stop battery drain?

 

I've read the owner's manual PDF, though not "cover to cover" and I didn't see anything about "stop battery drain" related to parking with a gear selected.

As for people parking Model T's, I just don't know. I'll let you get back to your desk work.

 

If any system can fail, so can the parking lock in an automatic transmission. I don't see how liability is the issue. I suspect GM didn't have a viable way to build the remote start system to handle both gearboxes, so they chose the more "comfort and convenience" oriented box. Storm in a teacup at this point.

I would like to have remote start, just to be able to get the engine warm in the mornings (I have a quarter mile uphill straight out of my driveway, so I allocate time to let fluids warm a little on really cold starts) and to let the a/c cycle the heat out of the cabin when needed. I can only hope some enterprising individual brings an aftermarket gadget that fools the GM remote start system into thinking it's bolted onto a Stingray with an auto box sitting in Park.

 

It takes, oh, 20 seconds to google "2005 corvette park in reverse" and find http://www.c6registry.com/technical/...e-Delivery.pdf, which is only 5 pages, and you don't need to get to the back cover:

I'm sure you have a theory that proves GM's TSBs wrong, though.

You do know the preferred term is "flat-plane crankshaft," right? Even if the people who make them can't quite spell "crankshaft?"

... it's ridiculous to think that the transmission is being damaged or put under undue stress when the car is parked and in gear.

Now maybe if a semi truck came along and hit the car and made it move 50 ft with the transmission in gear ... might want to worry about that, if there's anything left of the car.

 

There's all kinds of systems on every car made that "could fail" and cause a dangerous situation. Nobody has any trust in engineering anymore it seems.

 

There's some fantastic engineering there ... WTH were they even thinking? I take it this change in 2006.

 

Yes, but I still park my 2011 in reverse, just in case the year 2005 ever comes back.

 

I was merging your post with the other post, in the context of this being a C7 forum, there's no reference to using reverse in the PDF. Are you quoting an excerpt about parking safety or something to do with batteries or remote starting?

As for flatcrank, it's a pun.

 

Copy & paste from the 2002 Corvette Owner's Manual.

Parking Your Vehicle (Manual Transmission Models Only)

Before you get out of your vehicle, move the shift lever
into REVERSE (R) and firmly apply the parking brake.
Once the shift lever has been placed into REVERSE (R)
with the clutch pedal pressed in, you can turn the
ignition key to OFF, remove the key and release
the clutch.

I usually put mine in 1st gear before shutting off the engine to keep the clutch/torque tube rattle down. No mention of not putting it into reverse will drain the battery. I think that was just some weird snafu engineering thing that happened in 2005.
