Recall 15V639 covers 27 2016 Peterbilt 567, T680, 367, 384, 579, T880, and T800 trucks for reverse-gear lockup. Repair is free.
Peterbilt is recalling 27 of its 2016 567, T680, and T880 trucks equipped with Eaton Fuller FR 10-speed manual transmissions because reverse gear can stay engaged after the shifter moves out of reverse. The truck can unexpectedly move backward after shifting into neutral, increasing the risk of a crash; the dealer repair will be free once available.

What's wrong?
The recalled 2016 567, T680, 367, 384, 579, T880, and T800 trucks use an Eaton Fuller FR 10-speed manual transmission. The transmission routes engine power through selected gears so the truck can move in reverse, sit in neutral, or pull forward when the driver chooses a forward gear.
In the affected transmissions, the wrong bearing spacer was installed during assembly. That spacer belongs in an FA series transmission, not the FR unit used here. Because the spacer does not match the transmission design, the reverse gear does not always release when the driver moves the shift lever from reverse to neutral.
If the driver then shifts from reverse into a forward gear, the transmission can mechanically lock because reverse and a forward gear are engaged at the same time. There is no warning sign before failure.

A matching year and model does not guarantee inclusion. Check your VIN to confirm whether your specific truck is included.
What's the safety risk?
A transmission shifted from reverse into neutral can still move the truck backward unexpectedly, increasing crash risk. Use extra care after backing, keep the service brake set, and confirm the truck stays still before moving around it. Repair will be free at any franchised Peterbilt dealer once available.
What should I do?
- Check your VIN to confirm your 2016 Peterbilt 567, T680, 367, 384, 579, T880, or T800 truck is included in this recall.
- Review the owner letter from Peterbilt before scheduling service, since the remedy is listed as under development in this record.
- Contact a franchised Peterbilt dealer about the free transmission inspection and repair that fixes the reverse-gear engagement problem.
- Reference recall number 15V639 when you call the dealer.
- Avoid shifting directly from reverse into a forward gear until the truck is repaired, and watch for unexpected rearward movement after shifting out of reverse.
What happens at the repair
At the dealer, a Peterbilt technician will inspect the affected transmission and repair it if needed. The final dealer repair will be free once available. The repair addresses a condition where reverse gear stays engaged after the shift lever is moved to neutral, which lets reverse and a forward gear engage at the same time. Because the final process is not listed as available here, contact a Peterbilt dealer before driving in for service so the service desk can confirm recall 15V639 handling and parts status.
