42RH Help for Older Rear-Drive Chrysler Platforms

The 42RH is not the same conversation as a late-model computer-heavy automatic. It blends hydraulic shifting with electrical control for overdrive and converter lockup, so both sides need to be checked.

We see these units in older Dodge trucks, vans, Jeep applications, and Chrysler rear-drive platforms that still handle daily errands, towing, and northwest suburban commuting.

The inspection looks for fluid breakdown, leaks, band or servo concerns, overdrive electrical faults, converter complaints, and internal wear before we recommend a repair path.

How We Separate Electrical Control from Internal Wear

1. Confirm the 42RH application, engine pairing, prior service, and whether the vehicle still has its original unit.
2. Check fluid level, pan evidence, linkage adjustment, cooler lines, electrical connections, and lockup or overdrive controls.
3. Drive it when safe so we can feel shift timing, converter lockup, kickdown response, and hot-versus-cold behavior.
4. Build a written repair plan that names the failed system instead of lumping every 42RH complaint into one rebuild price.

That keeps a wiring or control issue from being confused with worn clutches, and it keeps a worn unit from being patched with a temporary adjustment.
