Now engine runs at 3 - 4000 rpm but the vehicle speed remains at 20 mph and transmission is not performing its shifting. Service engine light remains or and od light comes on flashing and transmission shifting is jarring and while traveling uphill transmission refuses to shift until road speed is reduced to 30 mph and shifting from this speed is not consistent until level road is travelled. Now it wont shift to another gear and speed is limited to 20 mph. Do you have installment plan for this expensive repair? Please advise me and help me. Thank you and mahalo.
