Your vehicle’s automatic transmission is one of its most complex and essential systems, and keeping it properly maintained is key to long-term performance. One of the most important aspects of automatic transmission servicing is replacing the transmission fluid at the correct intervals.
Automatic transmission fluid is responsible for powering, cooling, and lubricating the many moving parts within your gearbox. Over time, however, this fluid begins to deteriorate. Heat, friction, and debris cause the fluid to lose its effectiveness, leaving it dirty and unable to properly protect your transmission. If left unchecked, contaminated fluid can lead to poor performance, overheating, slipping gears, and eventually costly repairs—or even a full transmission rebuild.
At Castle Hill Tyres and Auto, our experienced mechanics provide comprehensive transmission servicing, including fluid checks and changes, filter inspections, and overall transmission health assessments. By replacing your fluid at the recommended intervals, we help ensure your transmission runs smoothly, operates efficiently, and avoids unnecessary wear and tear.
Regular transmission servicing doesn’t just save you from major mechanical issues—it also improves your vehicle’s performance and longevity. You’ll experience smoother gear shifts, better fuel efficiency, and the peace of mind that your transmission is well-protected.
Whether you’re due for a routine fluid change or have noticed warning signs such as rough shifting, delayed engagement, or strange noises, our team is here to help. Castle Hill Tyres and Auto offers expert, reliable transmission services to keep your vehicle in top condition.
Book your automatic transmission service today and protect your car from expensive breakdowns while ensuring a safer, smoother drive.
EXCELLENT Based on 261 reviews Seunghyoung2025-08-29Trustindex verifies that the original source of the review is Google. Recently, I had two tyres replaced and a wheel alignment done here. The staff were friendly and helpful, and the whole process took about 1.5 hours, which was reasonable. However, I was a bit surprised to be charged more for the wheel alignment, despite confirming the price multiple times over the phone. I’d recommend asking for a written quote beforehand to avoid any misunderstandings. I’ll make sure to do that if I return for another tyre replacement.

I had a funny new noise in my car, and after listening to the noise for 2 days, I was driving past so I pulled in. The boss got one of his mechanics to go for a 5 minute test drive. We pulled back into the garage, they got a spray bottle of soapy water, sprayed the intercooler hose, revved the engine and bubbles flew off the cracked intercooler hose. They walked across to a parts dealership bought the part I needed and fitted it on the spot! Problem diagnosed and fixed within 30 minutes with no notice. Thanks Castle Hill Tyre and Auto!

Thank you team :) Scott Gray2025-08-07Trustindex verifies that the original source of the review is Google. G'day This place is worth considering for sure. I'd be very surprised if you are disappointed. I phoned to ask a price on removing tyres from second hand rims. They quoted a very fair price & were excellent on the phone. When I got there the service was excellent. The office had 2 people working there & served me very quickly. I stopped by 7 times over a period of a week to drop off & pick up wheels both in the morning 8.00am & afternoon 4.45pm. Every time the office had 2 or 3 people to serve me. But the thing I noticed was the staff in the workshops were smiling & clearly happy to be there. On 4 occasions I was asked if I wanted a hand by staff already doing other things. I believe this great attitude makes a huge difference & while I didn't need help it's clear they appreciate their customers. I don't often write a review for a place unless their service or product stands out. I think it would be worth a phone call & see what you think for yourself.
