    :help: I have a 1998 Dodge Ram 2500 4X4 V10,and recently it has just started shifting at a high rpm and very firm going into 2nd gear and going into 3rd gear.Sometimes if I let off a little it will go into gear.I'm thinking sensor but maybe not.It almost feels like my tranny grew a shift kit over nite.If I get on some dry pavement and from a stand still and I put it to the floor it goes through the gears very smooth and nicely its only when I drive it nicely that it shifts firm in those two gears.And I mean firm like snap your head back firm...So what do you guys think? :confused:Oh here's another one why is it riding so damn rough lately.Ever since I replaced my track bar,sway bar links,pitman arm, it rides rough or is it just a coincidence,How do you know your shocks are junk on suck a heavy truck?

    have you checked the level ? Sometimes it will prolong the shift points that way.

    The only time I notice my shocks are bad is in winter with the blade on the front and my ballast (800-1000 lbs) in the rear. I have needed shocks for 3 years now... but I forget every spring.

    The valve body in the tranny could have dirt in it- one of the solonoids is probabily sticking tho. I had a very similar problem right after my tranny was rebuilt- it was one of the solonoids sticking. Check your fluid and maybe change the fliud and filter (if you have a shop you trust have them do the fluid and filter (adjust the bands while they're in there- mechanical adjustment in that tranny) and check out the valves.

    Check the TPS, it could be causing the problem your having.

    how many miles do you have on that truck, and when it shifts hard at what rpm are you is your trans shifting. Does it seem like the trans is holding in 2nd to long?

    Where is the TPS and can it be cleaned or does it have to be replaced?

    TPS is up on the throttle body, if I get a chance today I'll snap a picture for you and give you the procedure to test it. It may be able to be cleaned, most often though they need replaced.

    TPS(Throttle Position Sensor) is located on the throttle body on the opposite side of the throttle linkage, held on with two screws. If that tests ok, it could be the transmission pressure control solenoid or wiring. When the solenoid is bad or does not recieve signal from the PCM it defaults to allow 100% line pressure, resulting in hard shifts all the time regardless of throttle position. It is pulse width modulated and in layman's terms allows the PCM to perform the function of the old lever style rod you used to see on the older Mopars. If you have access to a scan tool, see if there are any trans codes stored. as not all trans codes will illuminate the check engine light.
