Shutting car off while in gear

[Bobby Fazio]

I can't ratchet up to neutral through the finish line. Is it safe to shut car off while in third gear through the traps? Will that stop the pump and lose lubrication in the trans? I want to check all the plugs after a run.

Bobby,

I do not know the solid answer but to me, it seems like a potential problem. I have visions of the pump pressure slowly bleeding off and causing what ever clutch pack is engaged to slip. A one time deal might be OK ??

In my opinion, I think your plug reading would be acceptable to just stop as quickly as practical and switch engine off as you near a stop.

Bobby, would be best I think to contact whom ever built your trans and run it by them first.

Bobby,

Congratulations for making it to the final at Atco last weekend. Great driving, and a close race.

Don't know what you have for a shifter, but the quarter stick shifts very easy from 3rd to neutral in a C4 with a reverse pattern. Pull back the lever and push right up. I had one for years before going to a PPP pneumatic shifter in my super stocker.

Another solution would be to call Joel's for a valve body with an electric neutral. I've heard mixed reviews about them, but I think that they make the only clean neutral valve body for a C4. I'm probably going to go that route too, since shifting back from 3rd with the PPP leaves something to be desired. You're almost waiting for that moment when it gets hung up in the pattern, and you don't reach neutral.

Good luck.

Clean "N" valve body will be the best and safest investment you can make
Call Joels he will set you up 248- 446-6024

Wouldn't it just be safer to switch to a forward pattern valve body?

I've run it by my dad a few times.. he doesn't seem to think it's a great idea lol, so I ran it by you guys instead!

I use the B&M Hammer which is a ratchet shifter so I can only go one gear at a time which makes up to neutral impossible. It's not a huge deal I do run an o2 sensor in the collector that records the entire run and that has helped tremendously in tuning but my next objective is to get each individual plug reading the same which is a great perk of EFI.

For what it is worth ATI doesn't recommend it at all - even with a Clean N. Once for a plug reading, okay that is cool. But the guys that do it ever pass are just reducing the life of the unit. In the pits, on the track, doesn't matter. When the engine is stopped, the transmission pump is not moving any fluid to lube the gearset that still being spun by the driveshaft.

I've been told in a TH400 clicking it into neutral causes the driveshaft becoming the driver and the way it multiples will cause one of the drums to spin to 20000 rpm+ and it can go boom.
