"Honest diagnosis, fair price, and the repair was done right. Chicago Transmission has been my go-to for years. Wouldn't trust anyone else with my car."

On a 2002β2005 Explorer with 5R55S, that's the 3-4 solenoid or coast clutch drum. Get a diagnostic β solenoid replacement is possible if drum damage is limited.
6F35 harsh shifts usually point to solenoid wear β often fixable for $450β700 without a full rebuild. Get a diagnostic before assuming the worst.
On V6 Explorers (2011+), yes β they share the 6R80. On 2.0L EcoBoost Explorers they use the front-wheel-drive-based 6F35, which is different.
3β4 business days.
The AWD transfer case (PTU) on Explorer is a separate failure point β fluid leaks are common. We service the PTU at the same time as transmission work.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
