RPM jump when slightly touch gas, Gear shift hard from Parking to any

[Weldmaster]

2012 Dodge journey Crew 6 cylinder FWD

1. history: gear shift hard some times during wither (more), some times in warm weather. Dealer had updated the software or flashing the PCM couple times, but not sure if there is any updates from about 2 years ago (when I got the last update). Generally, gear shift big bang disappear after update.

 

2. two days ago, car rpm jump up when slightly touch the gas pedal, then check engine light on.

after changed engine air filter (dirty), the gear shift big bang comes every time when shift gear from parking to any position. 

 

any advice for trouble shoot? 

Based on my reading from this forum:

Causes maybe:???

1. Mass air flow sensor dirty, need to clean

2. solenoid pack, 

3. update the software for PCM 

4. problem from the TIMP

5. transmission fluid change...

6. fuel pump filter clog: refer to the following

Thanks.

What year is your DJ? Up until mid 2012 they used the 4 speed auto for the 2.4l engine so that may play into what is wrong. Your best bet is to take it to the dealer and explain what is going on. If you are looking for someone who has had a similar problem here that information will probably help find people who may have had similar problems. Other than that you should either take it to the dealer or a specialized mechanic.

Got it fixed: changed solenoid pack, I am really surprised Dodge's quality control or the part supplier's quality control!

Had this kindly issue for 5 and half years and finally broken to left me out of warranty. Thanks for Eagle transmission and Street Brother for help.
