I am sorry your having this problem

do you have any access to a good multi meter ?

Customer: replied 1 year ago.
the trans fuze keep blowing
Expert:  Gary replied 1 year ago.

all of those things not working run off the trans fuse

if you unplug the big electrical connector at the transmission passenger side front next to where the 2 transmission cooler lines connect into the transmission will that fuse still blow ?

Unplugging the sensor you said stopped the fuze from blowing but it still dont shift
Expert:  Gary replied 1 year ago.

ok if that fuse stops blowing with the transmission unplugged then there is a solenoid shorted under the pan or the wiring harness is shorted under the pan

those are the only things that will blow that fuse

the pan needs to come off and the wires checked under the pan

It still backfires and miss will it clear up when i change the selinode
Expert:  Gary replied 1 year ago.

more than likely no

usually when these backfire there is a distributor failure or a bad cap and rotor
