1996 Chevy suburban transmission
My truck is an automatic but a week or 2 ago my 3rd
gear went out so I have to manually shift from 1st to
2nd and run that up to about 45 to 50 shooting my
rpms out the roof and shift to 3rd and coast. Gonna
change oil and add repair fluid but wanna know why
this is happening any info would be great thanks.
Check the codes, see if there are any transmission codes, you may have a bad shift solenoid or the TCM is locking out 3rd gear. If you do have bad solenoid I would replace them all.
