2018 Camry SE - Transmission hesitation and rough shifts, especially cold

Vehicle: 2018 Toyota Camry SE

Hey everyone,

I've got a 2018 Toyota Camry SE with about 75,000 miles on it, and I've been noticing some concerning transmission behavior lately. When the car is cold, especially in the mornings, it feels like it hesitates to shift from 1st to 2nd gear, and sometimes from 2nd to 3rd. It's not a smooth transition, more like a noticeable jerk or clunk.

After driving for a bit, it seems to smooth out, but the initial rough shifts are really bothering me. I've heard some chatter online about the 8-speed automatic in these Camrys having issues. Has anyone else experienced this? Is this something that needs immediate attention, or is it a known characteristic that might be covered by a TSB?

I'm wondering if it's a fluid issue, a software problem, or something more serious. Any advice on what I should check or mention to the dealership would be greatly appreciated before I take it in.

ClearTheCode admin answer:

This is a relatively common concern with the early iterations of Toyota's 8-speed automatic transmissions, particularly in the 2018 model year Camry. The symptoms you describe – hesitation and rough shifts when cold – often point to a few potential causes:

  1. Software Calibration: Toyota has released several software updates (TSBs) to address transmission shift quality issues. These updates aim to refine the shift logic and improve overall smoothness, especially during cold operation. This is often the first and simplest fix.
  2. Transmission Fluid Condition: While less likely at 75,000 miles if maintenance has been regular, low or degraded transmission fluid can contribute to poor shift quality. Toyota's WS (World Standard) fluid is designed for long life, but severe driving conditions can accelerate wear.
  3. Valve Body/Solenoid Issues: In some cases, issues within the transmission's valve body or with specific solenoids can cause inconsistent fluid pressure, leading to rough shifts. This is usually a more involved repair.

What to do:

  1. Check for TSBs: Contact your local Toyota dealership with your VIN. Ask them to check for any outstanding Technical Service Bulletins (TSBs) or software updates related to transmission shift quality for your specific 2018 Camry SE. This is often the most effective first step.
  2. Fluid Inspection: While a DIY fluid check isn't straightforward on sealed transmissions, you can ask the dealership to inspect the transmission fluid level and condition during your visit.
  3. Diagnostic Scan: If you have access to an OBD-II scanner, check for any pending or stored diagnostic trouble codes (DTCs), even if the check engine light isn't on. Codes like P0700 (Transmission Control System Malfunction) or other P07xx series codes would indicate a specific transmission issue.

When to see a shop:

Given the symptoms, it's highly recommended to schedule an appointment with a Toyota dealership or a trusted independent transmission specialist. Early diagnosis can prevent more significant problems. Be sure to describe the conditions under which the issue occurs (e.g., cold start, specific gears, etc.) in detail. If left unaddressed, persistent rough shifting can accelerate wear on internal transmission components.
