Expert RAM RAM ProMaster transmission service in Chicago. Free computer diagnostic, lifetime warranty on rebuilds, all years.
2014–present: 6-speed automatic (Aisin TF-80SC / ZF 6HP). FWD-only platform derived from Fiat Ducato.
The ProMaster's TF-80SC is an Aisin unit shared with Volvo and other FCA products — we stock all solenoid sets and rebuild kits. Fluid service with genuine Aisin/Mopar fluid resolves most shudder complaints. Solenoid body replacement cures most shift quality issues. Cooler line fittings are a wear item we replace with upgraded aftermarket units.
Mopar ATF+4 or Aisin ATF — do not use Dexron VI.
Fluid service: same day. Solenoid: 1 day. Rebuild: 3–4 days.
"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."
"The free diagnostic alone was worth the trip. They found the problem fast, gave me a written estimate, and completed the work on time. Exceptional service."
"Family owned and it shows. They treated my car like it was their own. The lifetime warranty on my rebuild gives me total peace of mind. Highly recommend."
Usually the solenoid body on the TF-80SC. These vans accumulate mileage fast in delivery service, and solenoid wear shows up as erratic, hunting shifts. Solenoid body replacement typically resolves it.
Fluid and filter service is done in-bay. Solenoid body and valve body work requires partial removal. Full rebuild requires a complete R&R.
Every 30,000 miles — stop-and-go delivery routes are hard on transmissions. Use only Mopar ATF+4 or genuine Aisin fluid.
The TF-80SC is a known unit and generally reliable with maintenance. High-mileage vans (150k+) in delivery service see solenoid and valve body wear — rebuild kits are available and we stock them.
Yes — the ProMaster City uses a different 6-speed unit (sourced from the Fiat 500L platform) but we service both variants.
Same-day appointments available. Honest estimates, no surprises. We've been doing this since 1987.
