2003 trailblazer trans not shifting corectly and reverse not working

#1
Please fill out the following to ask a question.

MAKE:chevrolet
MODEL:trailblazer LT
YEAR:2003
MILES:155500
ENGINE:4.0
DESCRIBE ISSUE....while driving made a bunch of noise and seemed to still go,ie. move forward.
Drove home but shifting of gears the engine revved to over 4K and had to feather throttle to get it to shift.
Reverse does not work
When test driving found that it appears to only have a couple of the 4 forward gears.

My question What years of transmission interchange to this 2003 model year?

Thanks

No reverse, no second, no fourth gears. Sounds like a stripped reaction sun shell. Salvage yards keep cross reference books as far as the interchange question.
