2008 chrysler town and country
 

i have a 2008 chrysler town and country that have recently displayed a check engine light with codes (p0734) and (p0792). the van will run 20 miles before it quits shifting but when the van is turned off and restarted it will run for another 20 miles, i have recently gotten a code reader and cleared the codes and check engine light but it does not matter check engine light or not the van will quit. my mother is handicapped and we dont have a lot of money so im trying to get more answers because we live in a small town without many car shops.

Thank you for your time !!!!!

PO 734 Gear 4 incorrect ratio
PO 792 ++Intermediate shaft speed sensor A circuit = _ range penformance
If your trans mission has a erratic shift chances our the trans needs to be repaired cost factor 750 - 1000 this repair can be been with out trans coming out its been a chronic problem

Thank you so much !!!!!
