46RE shifting problems.. erratic shifting.. shifting too fast ?
First of all forgive me for posting this on a dodge forum but the jeep forums cant seem to help or have no idea what my problem could be.
I have a 1998 Grand cherokee 119k miles with the 5.9 V8 engine and the 46re transmission much like you guys with the dodge trucks..
I'll try not to make this long but its kinda hard to explain so itll probably be long lol.. Basicly my Jeep shifts too fast it feals like anyway. Like when i start from a stop and give it quarter throttle give or take, the first shift is fine and does it right away as i reach around 10-15mph. The 2nd shift seems a little hard it doesnt clunk or make noises but you can deff feal the shift, when it shifts to 2nd it does this at around 2300rpm. The weird part is RPM's only drop maybe 200 and not even 2-3 seconds later itll shift right into 3rd, and 4th gear sometime after..
The thing is why does the 46RE shift so fast between 2nd and 3rd and is this normal ? When i say 2-3 seconds i mean it barely even drive in 2nd because within a blink of an eye or a breath itll shift right into 3rd.
The other and more pressing matter is sometimes when it goes right into 3rd itll drop back down to 2nd and then not even a split second later itll go back into 3rd. You can feal the truck moving foward then back then foward from the erratic up and down shift. Im not sure if its slipping, or if this is because the transmission didnt have enough time in 2nd before it went to 3rd and so it goes back to 2nd but then the when it does that vehicle speed has been picking up so it goes right back to 3rd. I feal like problem number 1 and this problem are related i feal its shifting too fast so thats why its doing this
Sometimes it feals like 2nd gear is pointless because how fast it shifts from 2nd to 3rd and it might as well go from 1st to 3rd.....
I have shifted manually and its alot better shifting like this.. Turn overdrive off. Start in 1st at a complete stop and once i get to 1800 rpm or so shift to 2nd and itll go to like 1600 rpm and when the RPM's reach 2200 ill put it into drive and itll shift to 3rd. Then i turn on overdrive a few seconds later and itll shift to 4th.
Basicly the timming is like 1st... 2 seconds later 2nd... 3 seconds later 3rd, 3 seconds later 4th..
The way its shifting automaticly however is more like this..
1st... 2 seconds later 2nd.. 1 second later 3rd, 3 seconds later 4th
The Jeep people have been telling me maybe its the Solonoid or something, but i dont have a check engine on and advanced auto parts didnt get any codes on the device they use... However im not sure if that device will reach transmission codes.. Wouldnt a bad part in the transmission turn the check engine light on on a older OBD2 vehicle like this ?
Also i should note, I bought this Jeep 2 months ago, and it did this when i got it but the transmission mechanic at the Jeep dealership said it was shifting normal when he drove it so i left it at that. Transmission fluid/filter has been changed and it isnt low. Its little below the OK mark when its luke warm (i cant heat it up in the 30F weather even after 30minutes of driving its still luke warm), I put 1/4 ATF+4 in just in case but i dont want to fil it to the OK mark when its not HOT because i know itll go up like an inch when its hot.
