   Up for auction we have a Transmission dipstick plug for almost all older GM transmissions with a .600 diameter dipstick tube. This includes TH350, TH400, 700R4, 200-4R, 4L60E, 4L80E

   READ: This is for engine or transmission pull and transmission storage only! This is not meant to be used in a operating transmission. This is only a mess free way to pull your transmission and store it while keeping dirt out. Nothing holds the plug in other then the o-ring friction.

 This is made of 6061 billet aluminum and is CNC machined for a precise fit. It also includes a  O-ring so you'll have years of trouble free operation. This is uncoated with a sanded finish. so you can leave as is or coat it as you like. This will also work with the rubber sleave many gm transmissions come with.

This fits where the transmission dipstick would go to keep fluid in and dirt out during pulling or storage. Again, this is not held in place securely and cannot be used in a running transmission.
