Ive got a '99 Dodge ram 2500 diesel, its auto and the tranny is starting to slip alot. I checked all fluids and I dont know what the hell is goin on, I use it for transporting materials, its got 130xxx miles on it, anyone got any suggestions ?

auto...manual? number of miles on it?

 

130,000 auto........

 

when was the last time it had a fluid change? how heavy a use has the tranny been put to....though autos are generally less abused than manuals, even they can fall apart...I'd definately change the flud, maybe the torque converter? dont really know enough about autos

 

Well, I used to haul about 2 palets of tile, thats about 1700 a palet. It was squating pretty good. but the ride was smooth. Other than that its been pretty light loads for about 6 months.

 

is it slipping in all gears? worse when cold or warm? is the OD switch flashing?

 

from 2nd and on, it does it when its warmed up. The OD is not flashing, when I put it in accsessory (sp) the light for the tranny will come on and nothing else. Its wierd, sometimes it feels like the fuel is cutting out and other Ill be at 40ish cruisin and itll feel like it pops into OD and back in here and there.

 

possible lock up solenoid malfunction, best to scan the tranny for codes, also always check tranny fluid in "Neutral" as the tranny pump does not operate in "Park" and will give you a false reading, i'm sure you already know that, but i see it so many times and at auto shops too, with 130K miles it sound like it might be getting ready for a rebuilt, as long as the OD unit is OK the rebuilt isn't too bad but to R & R and overhaul it will be around $1400 if you take it to a shop, about 1/2 or little less if you R & R yourself.

 

Did the check engine light ever come on??
If you can post your vin I'll check for any TSB's
