Richiano 19 Posted August 28, 2018 I have just got back from a 500 mile round trip to Norfolk, Lincolnshire from Wiltshire in my 2005 GS300 mk3 and i have noticed an issue with the transmission, When the car changes down a gear for instance when going down a hill or just cruising there is a noticeable jolt and a thud from the rear of the car somewhere? I thought i had seen people with similar issues somewhere but cant remember where. The transmission and diff fluid has never been changed to my knowledge and the car is nearly 13 years old but only done 70k. Share this post Link to post Share on other sites
Britprius 806 Posted August 29, 2018 Check the condition or the propshaft joints possibly the most likely cause. John. 1 Share this post Link to post Share on other sites
