    I am having a heck of a time installing my transmission dipstick tube. The engine and transmission have been removed and rebuilt on my 1990 Silverado C1500. (5.7L TBI V8 and a 4L60 transmission). Engine and transmission are back in the truck. Dipstick seal goes in and tube goes in all the way to the ridge in the neck and looks good, but the bracket wont fit over the stud in the bell housing. Looks like it needs 3/8" more to fit, but the tube is bottomed all the way in the transmission and I can't get it to go further. Any tips or tricks would be greatly appreciated. Has anyone else had this problem?

    Thanks

    Never mind -- its in now. It turns out the the dipstick tube bracket has to go directly under the main stud that goes into the bell housing. It won't fit over the secondary stud that sticks out to hold the electrical harness bracket.

    If you ever have the problem again with getting the tube in do the following. Put the tube without the dipstick in the freezer (shrinks the diameter of the tube by a few thousanths of an inch), put the rubber seal in the transmission from underneath and coat the seal with greese (ensures the tube slides in with less friction). Get the tranny tube in fast and it will swell and seal in.
