Transmission Issue (Codes P0700, P0731, P0755)
Transmission issue with my 2002 Dodge Neon SE - A/T
Several days ago while driving on the highway (50-60 mph) - the transmission seemed to downshift - and the rev's went through the roof (in the 5K-6K range). I now realize that the transmission was sent into "limp home" mode - and is only driving in 2nd (as well as reverse of course) at this point.
When pulling the codes - I received the following...
P0700 - Transmission/Transaxle trouble code
P0731 - GEAR RATIO ERROR IN 1ST
P0755 - 2/4 SOLENOID CIRCUIT
The only problem that I've had with this car in the past is having trouble with it going into gear for 30 seconds or so when starting it up on a cold day. This problem always resolved itself shortly - and hasn't came up for the last year or so. (As I recall - there's a TSB for this problem).
Any thoughts as to what may be happening here?
Thanks in advance!

Also, does anyone suppose that the P0731 code could be caused by a bad TCM? (Given the fact that it's skipping 1st gear altogether for "limp home" mode). I should also mention that the check engine light has been on since the initial problem happened about 2 years ago. (When I scanned it before, I believe I had a P0700 - as well as the P0731, but not the P0755).

I'm still leaning towards it having something to do with the solenoid pack at present.

Update!
I've reset the battery in hope to clear some of the codes - and have driven the car locally 4 or 5 times since then.
At this point - the P0731 and P0755 codes are completely gone - with only the P700 code showing up.
I'm taking it in for a TCM scan on Monday...but in the mean time...any thoughts?
Thanks,
Kyle

UPDATE:
Car just got finished at the dealer today. Initially took it in to have the transmission codes pulled (roughly $95.00 with tax) - and a bad Solenoid Shift Pack was diagnosed. Decided to use their factory part and labor - as well as flush the transmission. Part was higher than I wanted - but I'm happy it's fixed....
All in all...
Diagnosis - $95.00
Shift Solenoid Pack - $244.00
Labor - $135.00
Trans Flush, Filter, etc... - $189.00
With tax...about $700.00 out the door. High, but it's fixed.
Thanks for everyone's help!
