2 Answers
Buick's old Excelle model uses an Aisin 4-speed transmission. Below is relevant information about the Buick Excelle: Introduction: The Buick Excelle (Buick-Excelle) is based on General Motors' global platform. The prototype of the Excelle is a globally developed mid-size sedan by General Motors, primarily designed and developed by General Motors Daewoo Auto & Technology (GMDAT). On April 21, 2003, SAIC-GM's new mid-size car, known as the "mid-range Buick" Excelle, was launched. SAIC-GM officially entered the highly potential mid-size car market by introducing the "Buick Excelle Buick-Excelle" based on a new product platform. Model Positioning: The Buick Excelle is positioned as an entry-level family car, featuring a dynamic exterior and high-quality interior, offering the quality enjoyment of a "first car in life"; it comes with a new drive system that is smooth and fuel-efficient, and is equipped with the 10th generation OnStar assistance system as standard, including an onboard 4G-LTE mobile hotspot, eConnect intelligent connectivity technology, and supports Apple CarPlay and Baidu CarLife.
I've been driving my old Excelle for over a decade. That four-speed automatic transmission is GM's in-house 4T40E model, used in both 1.6L and 1.8L automatic Buick Excelle models from 2003 to 2009. This transmission is exceptionally durable - I only changed its fluid once at 200,000 km. The only downside is its slightly sluggish gear shifts, and fuel consumption can spike to 12L/100km in city traffic jams. But parts are cheap - replacing a solenoid valve costs just a few hundred yuan, and any ordinary repair shop can handle it. While modern cars now use 8AT transmissions, these older units win with simpler maintenance, making them ideal for budget-conscious owners. Just watch out for gearshift jerks and oil leaks when buying used.
