Difficulty changing gear, juddering, sluggish acceleration: these symptoms often point to a fault with the gearbox in your Peugeot 307. This complex component comprises many parts, and the root cause of a problem is not always obvious. EDEN BOITES is here to help you make the right decision when faced with a Peugeot 307 gearbox failure.
Peugeot 307 Gearboxes
Launched in 2001 and named Car of the Year 2002, the 307 spanned two generations. Petrol variants in the first generation came with 1.4 (75 bhp), 1.6, and 2.0 (138 bhp) engines, paired with a 5-speed manual gearbox or, on the 1.6 and 2.0, a 4-speed automatic gearbox. The 1.4 HDi (70 bhp) and 2.0 HDi (90 or 110 bhp) diesel models were fitted with a 5-speed manual gearbox.
The 2005 facelift brought revised outputs: 1.4 petrol (90 bhp), 1.6 (110 bhp), 2.0 (140 or 180 bhp), and 1.6 HDi diesel (90 or 110 bhp), with the 2.0 HDi uprated to 135 bhp — the latter available with a 6-speed manual or automatic gearbox.
Signs of a Gearbox Problem
Over time, the gearbox can show signs of wear:
- difficulty, or complete inability, to select gears;
- juddering when changing gear;
- a soft or spongy clutch pedal;
- grinding or rattling noises;
- loss of power.
Common Problems and Solutions
If you suspect a fault, take your car to a mechanic: diagnosing the issue requires the gearbox to be removed. The inspection may reveal:
- worn synchromesh rings, causing difficulty selecting gears;
- deteriorated rings or seals;
- a faulty torque converter, on automatic gearboxes;
- broken gear teeth, causing grinding noises;
- a defective mechatronic unit, which controls the gearbox;
- low or contaminated transmission fluid.
Depending on the diagnosis, the technician may replace the faulty component (synchromesh rings, torque converter, mechatronic unit) without necessarily replacing the entire gearbox, repair the casing or seal and top up the fluid, or carry out a fluid change. If none of these remedies are sufficient, a full replacement will be necessary.
Replacing the Gearbox on Your Peugeot 307
When a full replacement is unavoidable, you can purchase the gearbox separately from EDEN BOITES and have your mechanic fit it — a more cost-effective solution. Our reconditioned gearboxes cover the various engine variants of the 307, all listed in the Peugeot gearboxes collection. You may also find our guides on the Peugeot 306 and the Peugeot 308 useful, as well as our comparison of manual and automatic gearboxes.
Frequently Asked Questions
How do I identify the gearbox model fitted to my 307?
The engine type, year of manufacture, and number of gears are a good starting point, but the gearbox code stamped on the casing is the most reliable reference.
What is a torque converter?
It is the component fitted to automatic gearboxes that transmits engine torque. When it fails, it causes noise, vibration, and gear-change problems.
What causes grinding noises when changing gear?
This is often down to worn synchromesh rings, damaged gear teeth, or insufficient lubrication. A proper diagnosis will identify the exact cause.
Is buying the gearbox separately more cost-effective?
Yes: you order the reconditioned gearbox from EDEN BOITES and have your mechanic fit it, which reduces the overall cost.
