This is gonna be a poster-child I bet --- but TYPICALLY when you lose Reverse, the sun shell is fractured or the splines are gone.

This is the big reason WHY --- at the time of rebuilding, we ALWAYS install a hardened shell.​

​

Now --- the reason why you cannot put the dipstick back in --- therein lies the mystery --- might it be shrapnel from --- the drum? --- not likely.

Perhaps the valve body unbolted itself and fell into the pan and that's why the stick won't go back in.

BUT --- let me cogitate on that for a moment ---- <ahem>

1. The filter didn't fall off --- that would affect Reverse but also any other forward gears too.
2. Did the dipstick tube come outta the transmission and you are running into the outside of the transmission case? --- Again --- not likely.
3. I got nutthin' here at this point ...

You HAVE to drop that pan.

I want pictures and numbers, lines and arrows under the pixs, explaining what happened --- and paragraphs that aren't one-big-blob of words.

OK?

Thanks for the Reply! I had to look up the word "cogitate" nyuk nyuk nyuk.............

if it is the sushell gear does it usually require a complete rebuild?

It would be wise to not just repair a transmission "of age".

But ... we ... us ... don't really have any idea of all the circumstances involved here. You've got a strange-o situation here and it becomes behoovant to drop that pan.

The proof will likely be in the pan ... on the magnet ... next to the pile of clutch powder.
