2000 dodge caravan 41t tranny probs

[jimmyjames]

ok this is my prob, i took my 2000 grand caravan sport on a 240 mile trip all highway the morning after i reached my destination tranny went into limp mode i replaced output sensor as well as input sensor dropped the pan replaced fluid and filter atf4 i might add,and also cleaned all electrical connections took it out for a test drive and shifted it fine untill the fluid started to get to normal operating temp, then it went right back into limp mode and that was that, i also noticed that when i dropped the pan there was the normal amounts of metal shavings for a vehical with 120,000 miles so i wasent concearned about that, i am going to replace the solenoid pack and see what happens , my question is has anyone else experianced any similer problem like this, and if so what worked thanks jimmyjames clearwater fl

i experianced this same prob and had to rebult tranny cuz there was bad seals and when she got hot she quit but if yall have her scanned and look at cvi's and data stuff then the probs will show up so ya aint just stabbing in the dark

Welcome to the forum. First thing i would have done, was pull codes from the TCM.Just like circumventor said, you just can't throw parts at the transmission.

[jimmyjames]

yeah i pulled the codes and corrected those probs , and i am waiting for the delivery of a new solinoid pack i found on e bay for 1/4 of the price the parts stores are getting. i am also looking for a tfp manual valve postion switch thats located in the valve body, i found that these can get real tempremental from normal wear that ocurrs in and around the valve body which can cause them to malfunction. ill keep you guys updated on the situation and the best fix, its become a vendetta between myself and this tranny. i would also like to add, back in the days before they made all these transmisssion sensors and computors it was very easy to diaignose a tranny prob just by pulling the stick and smelling the fluid and looking for shavings i miss those days. also the function of the tcm and solinoid pack is silly it dosent really help performance that much and it cause a great deal of problems for your average joe that has no idea what to do when this happens so he has to spend a bundle of money mostly in diagnostic labor to figure out a 50 or hundred doller problem if the guy is a honest tech otherwise he will get soaked with a 2000 doller bill to replace the tranny, sorry i liked things when they were simple. anyway thanx for the support jimmyjames clearwater fl

These transmissions are soooooo much easier to diagnose than the old stuff. A real scanner with data pinpoints the problem in seconds. The codes get you in the ball park, the data pinpoints the issues. I'll take any of these electronically controlled transmissions over the old hydraulic systems. And parts are cheap... if you know where to go. I've collected a lot of the parts over the years, so when I come across a 'bad' trans I can get it fixed up quick and cheap...unless it's internally bad.

[jimmyjames]

yeah the tcc and the diagnostic codes will get you a ball park idea but the older th 350 or c4s when they let go they let go so i have to disagree with that statement if you dont know how to test electrical circuts and diagnose theses things your basically stuck i understand the concept of the engineirs at the big 3 but in my opinion its just a big hassel as opposed to the benifits, on the other side of the spectrum i truly beleve that monitoring of the engine functions via the pcm has made it possable for the new engines to make lots of horsepower and run 100 percent more efficiant than the older ones, have a great day jimmy james clearwater fl.

Tell you what, I've built a ton of 350s, 400s, 440th, 200r4, 700r4, axod, aod, c4, c5, c6, fmx, aod, a500/518, 727/904 and many other units. i'll take the 604/606 any day. the simplicity of this trans, huge data capacity makes it gravy for diagnositics. i never had one that lead me down the wrong path to figure out why its causing problems. I even found cross leaking with cvi's and quick hydraulic test. on a gm trans you only get one hyd port to measure line pressure. I remember a th350 that really kicked my but because of a hairline crack in the worm paths that cross leaked and caused clutch drag. every 300 miles, the intermediate cluch burned up.
