2000 dodge 3500 4wd diesel 47re i think. takin off in 1st is fine but it dont shift into 2nd on its own. if i let off the gas it then shifts into 2nd on its own then will go into 3rd as it should on its own. if i put it in 2nd manually it just slips like it is in neutral. this just all of a sudden happened there was no slow arising to the problem. someone please give me your suggestions. thanks

 

Usually, not going into 2nd.... or 3rd when it should indicates a bad Governor Pressure Solenoid.... or the Transducer (pressure sensor).
Can also refuse to downshift into 1st at a stop.... and several other strange variations.
Sometimes hard to tell which so worth changing both if they are original.

I've not seen the slipping you mention...??

Easy DIY R&R after dropping the pan.

Likely that KD band badly out of adjustment. When was last serviced? What is condition of fluid?? If threads do not protude beyond jamb nut on KD adjsuter, than band is worn out. You can verify by dropping pan. If nothing wrong with band than the gov pres solenoid is questionable'

 

there i s no slipping, i have no 2nd gear all of a sudden i thought it was going in after i let off the gas but it was going into 3rd. so i completley 2nd gear.

 

thanks dozer,,, thats what the tranz shop told me today. i have no second gear at all. they told me the band is completley out i guess, so i went and bought a new trans today. 1/2 a million miles and first tranny ent out at 400,000 second one at 96,000 hopefully 3 WILL LAST LONGER

 

well i picked up a trans from the recycling yard last week. it had 125,00 on it and we put it in and it is junk. first there is no 1 but 2 and 3 work great then all of a sudden 1 works and no 2 and 3. i am done with this crap. the tranny shop is now rebuilding my origanal and they are building it much tougher. i can not wait. every tranny i have had in there has been used and you never can trust em so i was always easy on it. i cant wait for my new tranny. costin me 3000 but should be worth it.
