I dont think anyone would ever argue that the ZF8 isnt the better transmission of the bunch. Do you know whats wrong with the OP's and mine Ford transmission? We would both appreciate your insight.

 

Hello there. Feel free to send us a DM with your vehicle's VIN and mileage. We'd be happy to look into this for you.

 

Great thanks. With a little searching I found a TSB that describes my issue to a tee. Its TSB# 22-220 I'm going to make an appointment to hopefully have it done and will report back.

 

We own a 2023 F350 7.3 purchased new and a 2023 Ram 2500 6.4 purchased used with about 10k miles on it. The 8 speed ZF transmission in the Ram is hands down a much better shifting transmission.

 

Mine does it in 4th gear. To me, it seems like the truck wants to shift gears, unlocks the TQ converter, then decides not to shift gears and locks the TQ and then decides it needs to shift gears and so on. My research after getting mine led me to believe that, as others have said here, this is a flaw in the programming of the transmission and not an actual mechanical issue. I now either touch the brake or lightly touch the gas to keep the transmission from thinking it needs to do anything.

 

Can you post the text to the TSB? If it is fixable, I would love to get it fixed.

Repair/Claim Coding

Causal Part: RECAL
Condition Code: 04


Service Procedure

1. Reprogram the PCM using the latest software level of the Ford Diagnosis and Repair System (FDRS) scan tool.

NOTE: Advise the customer that this vehicle is equipped with an adaptive transmission shift strategy which allows the vehicle's computer to learn the transmission's unique parameters and improve shift quality. When the adaptive strategy is reset, the computer will begin a relearning process. This relearning process may result in firmer than normal upshifts and downshifts for several days.

 

The last company I worked at before starting my own had sold off the last 2 F-550s in the fleet and bought 2 new 5500s because "the Fords always needed their front suspension repaired too often". Those Fords were the best trucks out of a fleet of 30+ of various makes and models up to class 9, and literally the only time they would go down was because some driver couldn't avoid pot holes and curbs.

Those 23 Ram 5500s were delivered with ~100 miles on the clock, and by the time they hit 1k they would randomly shift into neutral and scream "TRANSMISSION FAULT" on the dash and just start rolling down the nearest slope. Forward, reverse, park, it didn't matter. If the engine was on you had to shut the truck off and restart it to get the gears back.
Dealership said no clue, no recalls. Drive it til it breaks and then bring it back in.
Two weeks later one of the trucks spit the PTO across three lanes of traffic, jammed up the highway, and needed an emergency heavy duty tow back to Dodge.

 

Son in law works for a boat dealership They have a fleet of six ram 3500s. All had transmissions rebuilt 85k several by 65k. The newest truck just went down with 65k miles. All brand of trucks have some issues.
