04 ram 5.7 Transmission p0700 733 734 735
I really appreciate any help on this. Current 182k.
155k mile trans fluid/filters changed, very very dirty.
Last week all of a sudden my RPM's would increase as if gears slipping.
I checked fluid and it was fine.
I happen to check engine oil and it was very low, but dash showed no sign of engine running hot.
engine light came on giving these codes p0700, 0733, 0734, 0735.
I tested input speed sensor and found no ohms, replaced it.
Problem stopped, but engine light did not reset all weekend.
Yesterday I drove and all of a sudden trans shifted fine 1-2, but would not come out of 2nd gear.
Codes tested same again, spd sensor ohms still good.
Trans pressure sensor tested 50/150 ohms, replaced with new one 100/100 ohms between contacts.
This did not change this current problem.
I drove home 15-20 mph in 2nd gear.
I dropped trans pan and definite smokey smell but not terribly burnt up.
Little shavings but probably from driving home in 2nd.
Vent tube on top of trans is very dirty/greasy.
Tempted to put oil/filters in and see if problem was fluid/filter related, from old trans oil being so bad.
Not sure if I can check any other additional sensors in driveway before putting pan and oil back in, hate idea of draining/wasting new oil if it needs trans shop service.
I really appreciate last minute advice before I call tow to get it to trans shop.
