Do you still have second gear? If not, you lost the band. Otherwise, IDK and I'm curious. I've read that no fourth can be a problem with a servo seal.

yup

so it's rebuild time

do a search on this site (that's a hint) and any other site where the 700r4 or 4l60/e are discussed and you will see no 3rd or 4th is very common

It's your transmissions way of saying it wants you to spend money

Re: 700r4 wont shift 3-4

happened to mine too. after about 50 miles on the new rebuild trans, 3-4 didn't work. the band broke to go in 3rd gear. so i needed a new trans or rebuild the one i had. if they are not rebuilt right, or been sitting awhile like mine did before it got used. bands break very easily. did it shift really hard through all the gears? mine did, way too hard. got my transmission for $100 and it works even better than the new rebuild one.

DISCLAIMER


you are the exception and not the rule

$100 transmissions tend to be just that; $100 transmissions

many who feel the onset of transmission slippage will install a shift kit on the advice of their inexperienced friends. Others will change the tranny fluid and filter. Both are desperation plays trying to ignore the obvious

good luck
