this 02 durango with a 5.9L engine just had its tranny replaced, now it has a error code PO733. This is a brand new tranny. barely 1 mile on this tranny. Please help.

 

Can't help except to say my list says that code is:

P0731-GEAR RATIO ERROR IN 1ST
P0732-GEAR RATIO ERROR IN 2ND
P0733-GEAR RATIO ERROR IN 3RD
P0734-GEAR RATIO ERROR IN 4TH
P0735-GEAR RATIO ERROR 4TH PRIME
P0736-GEAR RATIO ERROR IN REVERSE

can the people who supplied/fitted tranny not help ?

was the new trans installed by a shop? if so i would say they need to be fixing it as part of what you paid for. If not it should still be covered under the trans warranty. Not really sure what would cause this besides transmission itself, maybe one of the speed sensors is bad? but they usually throw their own code.

 

Unfortunately the shop went out of business.

 

Barely 1 mile on it? must have been a really short test drive (insert red flag here). No offense but, I can see why there out of business.....

P0733 is a gear ratio error and in lamens terms, they put something together wrong internally and the only way to fix it is to rebuild it (again). Anyways, sorry to break it to ya but you have been hosed and your only recourse at this time (being out of business) is through a court system.
