Looking for some help. (thanks for reading this lengthy thread and chiming in…here goes…)
I performed a drain/fill (and filter replacement) on my 2011 JGC and now I get intermittent rough starts (constantly cranks but wont turn over), if it decides to turn over, sometimes will sputter and stall out. This happens during a remote start or trying to do a manual start (pushing the brake and using the push button, or key).
Funny thing is this didnt happen before I did the transmission service.
I used AMSOIL (signature series ATF...made sure ATF+4 was listed) and a WIX filter kit (specifically one for 4WD).
I drove the vehicle around to get the fluid warm and then proceeded with dropping the pan w/o making a mess (one side at a time). Once the pan was down I proceeded with replacing the filters. First the round filter, filter came out easily once I got the right wrench, but the neck of the filter (part with the threads separated from the actual filter body), no biggie, I just unscrewed that portion and then installed the new round filter (after I "pre-charged" the new filter with ATF fluid) and hand tightened down. Now for the rectangular filter, removed the screw and removed the filter but left the existing seal (figured after reading the warnings of placing the seal on the pump body and not the filter neck, leaving the existing one on the pump body would eliminate any issues if I would have attempted to remove and replace it….was this my mistake to not replace it?...the cause of my problems?). I made sure the filter neck was properly seated up into the pump body and up against the seal, re-installed the screw on the filter (tightened by hand a good amount – not checked to 40ft-lbs….could this be the issue also?) For the pan I cleaned off the existing gasket and wiped down the pan, also cleaning off the magnet at the bottom of the pan. I placed a continuous bead of RTV gear sealant around the pan the placed the rubber gasket from the kit on the pan, on top of the rubber gasket I put a thin layer of the RTV gear sealant and proceeded with reinstalling the pan. (Did I miss any steps?)
I let the sealant dry for about 30-45 min before proceeding with refilling with transmission fluid. I re-filled using 6.5 quarts (mentioned on the wk2jeeps and the amsoil site). When I attempted to start the vehicle that’s when starting problems started happening, two or three attempts resulting in long cranks until it basically timed out. I figured at first maybe the trans fluid levels were low or didn’t get to all parts of the trans so I shifted through the gears. I checked the fluid level and it was a bit low so I added more ultimately until I’ve added a total of about 8 quarts (since I serviced it on Sunday).
This morning, the vehicle wouldn't start at all
, just constantly cranking. Even dropping the trans in Neutral, the vehicle wouldn't start. I thought maybe it’s the battery, so I connected my black and decker 10amp charger and alternator tester and the battery level indeed showed being low, so I let it charge a bit (45-min, showed the battery was in the green “charged”, but stopped it before the green indicator light appeared) and attempted to start it again…nothing, long cranking until it timed out again. Couldn’t do more troubleshooting as I had to be at work. Once I get home I'll try leaving the charger on longer and see if there's any change.
Is it possible that doing a drain/fill/filter replacement can cause starting issues? Anything else I should look for to troubleshoot?
