B&M has designed this Locking Short Dipstick to be used in conjunction with a trans shield that attaches to the servo cover of standard
Powerglide and Dedenbear transmission cases,
The dipstick's knurled, screw-on cap is machined from billet aluminum and has an O-ring seal to prevent leaks. The dipstick plugs into the transmission
with a sealing grommet (standard on most new GM transmissions).
