2000 Dodge Durango Stuck in 1st Gear
Suggested Repair
Have the transmission diagnosed properly, including a computer code scan even with no check engine light, and review whether the filter has been serviced on schedule. A hanging valve is possible; if internal work is required, address related components or consider a quality rebuilt transmission such as a Jasper unit.
Conversation Summary
The owner of a 2000 Dodge Durango with 140,000 miles reports the automatic transmission will not shift out of first gear, limiting speed to about 20 mph. The engine runs smoothly, there is no grinding or roughness, and the check engine light is off. The owner questions whether a roughly $2,200 rebuild is necessary or if a service would suffice. The expert advises checking the maintenance schedule, noting the filter is typically due every 15,000 or 30,000 miles, scanning for codes despite no warning light, and considering a stuck valve. Proper diagnosis is recommended, with a quality rebuilt transmission such as a Jasper unit if replacement is needed.
