Locking Dipstick

Michael Pliska · 01-12-2010, 06:22 PM

From another forum, the GM part number is 15687192. It's supposed to be longer than a standard powerglide dipstick, so you can just cut it to match your existing one.

I picked one up yesterday. Had to pay list price at $15, but the only dealers with stock were ones I couldn't get a deal at. GMPartsDirect.com has them cheaper but their shipping was over $15! It's a basic locking dipstick that is REALLY long, so you can cut it to match your existing dipstick. I'll post photos after I cut and fit it. Hopefully the NHRA continues to accept these.

Best remember the locking feature requirement includes the base being secured to the trans, no more stick it in with sealant and forget it...

The Lokar unit is hard to put in on your back. The locking nut is a tight fit and there isn't much room for a wrench to turn the top piece on a t400. The trans brake selinoid is in the way. Doing it on a rack would probably be easier. Having someone else do it would be easier yet. Us old guys aren't as flexible as we once were.

Update on Lokar dipstick. If you have a door car with not much firewall clearance the trans mount dipstick won't work. You can't get to it to fill with fluid or release the dip stick. Go with the firewall mount.
Anybody want to buy a Lokar locking dipstick trans mount for a turbo 400?

I now have an older B&M dipstick that has the rubber on top (inside) when you tighten up the handle on top it expands the rubber. Is this considered to be a locking dipstick or does it need to actually lock down ???

Is NHRA worried about the dipstick coming out of the tube OR the fill tube coming seperated from the transmission case??? OR fluid coming up out of the fill tube???--Comp387

HELL who knows,....

Jim, your saying that what 63vette and I have won't pass tech ?

The Hughes I have is on NHRA's approved list so I should be OK, but you never know who you may get as a tech person at a race. I once was told at a National Event I needed a complete cover on the fuel cell. I asked for the head of tech to take a look and he told the tech in no uncertain terms that was not needed. Even after that the original tech person told me it would be a good idea to do over the winter. Just a wanna be tech person I think is what he was.
I think NHRA is actually worried about the dipstick coming up an fluid getting out.
The problem there is that most all trans have a vent lower than the dipstick which will bleed oil first.
I also use a small puke tank on the vent and I would think the puke tank would be of more use than the locking dipstick.
Just My 2 Cents
