I want to seal off the dipstick tube on my TH400 with the newer-style locking dipstick. A couple questions:
* Did Chevy ever install that locking-handle style dipstick on the TH400's? My local tranny parts-supply place only carries the slip-in style for the 400's, but the locking-style for the TH700R4.
* Does the locking-handle style dipstick work with the original tube, or does it require a special tube as well?
* Anyone have a part-number handy for a TH400 locking-handle dipstick and/or tube? There are no decent parts-counters at dealers in these parts, and GM Parts Direct works best if you already have the number handy.
