Jetour X90 Transmission Slipping: Why It Jerks and What to Do

Why Your Jetour X90 Transmission Feels Jerky

If your Jetour X90's automatic transmission slips between gears with a delayed, jerky engagement, you're not imagining it. This is a common complaint, especially with dual-clutch (DCT) or modern automatics. The transmission is struggling to smoothly connect engine power to the wheels. It might feel like a hesitation when you accelerate, a thump when it finally engages, or a slip where RPMs rise without acceleration. While it can sometimes be a simple fix like low fluid, it can also signal worn clutches or electronic issues. Don't ignore it — driving with a slipping transmission can cause further damage and may be unsafe.

Likely Causes and What to Check First

Start with the easiest and most common culprits before assuming the worst. Here's what a mechanic would check, in order:

• Transmission fluid level and condition: Low or burnt fluid is the #1 cause of slipping and jerky shifts. Check for leaks and proper level (some Jetour models require a specific procedure).
• Fault codes: Scan the transmission control module (TCM) for stored codes. This can point directly to a faulty sensor or solenoid.
• Speed sensors: Input and output speed sensors tell the TCM how fast the shafts are spinning. A bad sensor can cause delayed, harsh engagement.
• Solenoids and valve body: Clogged or failing shift solenoids can't regulate fluid pressure properly, leading to slips and jerks.
• Worn clutch packs (DCT) or bands: If the fluid is fine and no codes, internal wear may be the issue — especially on higher-mileage vehicles.
• Software/adaptations: Sometimes a TCM reflash or relearn procedure can smooth out shifts.

Is It Safe to Keep Driving?

If the slipping is mild and only happens occasionally, you can probably drive carefully to a nearby shop — but avoid hard acceleration and highway merges. However, if the transmission slips badly, hesitates for seconds, or jerks violently, stop driving. It can leave you stranded or cause an accident. A delayed engagement when pulling into traffic is a serious safety risk. Towing is cheaper than a new transmission. Get it diagnosed by a transmission specialist familiar with Jetour models as soon as possible.
