welL what transmission is really there, 2001 year.Dodge RAM 1500 pickup I guess.
many this old 21yo have the wrong box, and wrong gear ratio's now.
or has TV cable or has vacuum modulator bad.
as transmission evolved fast, the cable TV and modulator was no longer used, (and both delay shifts)
the E box, TCM that knows load on engine
this is mix of old and modern Eboxes
dodge name is 42RE; Trans. code 46RE
and knows vacuum and throttle angle and shift by engine load
and throttle angles and by road speed. (VSS)
scan the PCM/TCM yet,see if it is not happY> that be first of sure and Ebox.
it has TV cable and gov. modulator that both can fail.
cable rusted and suck open is common'
it has EPC tool pressure mudulator that if fails so do shift points.
Tranny 46RH goes on 94-97 & 46RE goes on 97-02 trucks.
the difference is a 46RH is a transmission with a lock up torque converter, and over drive, also Hydraulically controlled (note the H in 46 RH) the 46RE is a transmission with a lock up torque converter, and overdrive, it is electronically controlled (note the E in 46RE) make sure your doing like for like.
E should have wires going to the drivers side of the tranny and a wiring harness bundled up there with zip ties.
hope this helps and good luck! don't smash any fingers putting the new/used one in! ck the output splines too count teeth.
not knowing the model and year it is hard to know what trans you have. GM has TSB Technical Service Bulletin for this issue. If you had a repitable shop rebuild it this should be under warranty. Also should have a check engine light on you can have the code pulled and Google the code that may help also. Hope this helps.
There was a Technical Service Bullitin (TSB) out(TSB21-11-00) for this problem. It applied to 00-01 trucks with a 46RE built before 08/01/00 It had to do with replacing a pressure boost valve cover in the trans. That was after only performing some tests with the DRBIII first to rule out trany wear causing the fault.
TSB's are written for the dealerships by their respective manufacturers. They usually cover a problem that has occured enough times under warranty to warrant giving the dealership a heads up on the problem and how to fix it.
you need to check your ignition system it seems like you have a coil or module or crank sensor breaking down you should see if you have any stored codes good luck
