"How much does transmission repair cost?" doesn't have one honest answer — because transmission problems range from a $150 fluid top-up to a rebuild costing thousands. Anyone quoting a number before diagnosing your vehicle is guessing. Radman Auto Repair diagnoses the actual cause of a shifting problem first, then gives you a real number for the real repair — not the most expensive possible outcome.

Radman rule: a slipping or rough-shifting transmission is not automatically a rebuild. Fluid condition, sensors, and solenoids are often the actual cause — and cost far less to fix.

Signs of a Failing Transmission

Slipping Gears

Engine revs rise without a matching increase in speed — the transmission isn't holding gear properly.

Delayed or Rough Shifting

A hesitation before engaging gear, or a hard clunk when shifting between gears.

Grinding or Shaking

Vibration or grinding sensation during gear changes, more noticeable under load.

Fluid Leaks

Reddish or brownish fluid under the vehicle — transmission fluid loss can quickly cause more serious damage.

Burning Smell

Overheating or degraded transmission fluid often has a distinct burnt smell.

Warning Lights

Check engine light with transmission-range codes (P0700–P0999) — see our check engine light diagnostics page.

How Much Does Transmission Repair Cost?

Transmission repair cost depends entirely on which of the following actually applies to your vehicle:

Fluid Service

The least expensive category — a fluid and filter service, often $149+.

Sensor or Solenoid Repair

A mid-range repair — often mistaken for a bigger problem until properly diagnosed.

Rebuild or Replacement

The most expensive outcome, reserved for internal mechanical damage — confirmed only after diagnosis, never assumed upfront.

We won't quote a rebuild before confirming that's actually what your vehicle needs. Call (416) 742-4521 to book a diagnostic and get a real number for your specific problem.

Preventing Expensive Transmission Repairs

Regular transmission fluid service is one of the most cost-effective maintenance items you can do, and it directly reduces the odds of an expensive rebuild down the road. Old, degraded fluid loses its ability to lubricate and cool internal components, which accelerates wear on parts that are expensive to replace. If it's been a long time since your transmission fluid was checked or changed, that's the first thing worth addressing — often long before symptoms appear.

Frequently Asked Questions

How much does transmission repair cost?

It varies enormously depending on the actual problem, from a fluid service to a full rebuild or replacement. Radman diagnoses the specific cause before quoting rather than assuming worst case. Call (416) 742-4521 for an estimate after diagnosis.

What are the signs of a failing transmission?

Slipping gears, delayed or rough shifting, grinding or shaking during shifts, fluid leaks, a burning smell, and warning lights are the most common signs.

Is transmission fluid service cheaper than transmission repair?

Yes, significantly. Routine fluid service is one of the least expensive maintenance items, while a rebuild or replacement is one of the most expensive repairs a vehicle can need. Regular fluid service can help prevent the more expensive outcome.

Can a transmission problem be something minor?

Yes. Some shifting complaints trace back to low or degraded fluid, a faulty sensor, or a solenoid rather than internal transmission damage. Diagnosis is what tells the difference — not assumption.

Does Radman work on automatic and manual transmissions?

Yes, Radman diagnoses and services both automatic and manual transmissions across most makes and models.

Alex is a great guy. He took the time to respond by phone and walk me through my options for my Tesla Model Y 2024 and gave me his perspectives as a Tesla owner. Top recommendation in my books for the Toronto area.

I cannot say enough good things about Livio and the team at Radman Auto Repair in Rexdale. We brought in my son’s 2015 Mitsubishi Lancer because the A/C was malfunctioning. We had already been to two other shops, paid for diagnostics, and received different explanations, so we were frustrated and unsure what to do next. Livio was outstanding. He listened carefully, looked at the issue, and explained everything clearly and in detail in a way that actually made sense. He was able to narrow down what was going on within minutes, without guessing, pressure, or recommending unnecessary work. What really stood out was that he did not charge us another diagnostic fee after learning we had already paid for two separate diagnoses. Even better, the work was completed the same day, which was a huge relief. It is rare to find a mechanic who is knowledgeable, honest, patient, efficient, and genuinely focused on helping customers understand the real issue before they spend money on repairs. Livio truly gets it. We are so happy we found Radman Auto Repair and would highly recommend Livio and his team to anyone looking for trustworthy, skilled, and customer-focused service..

My 2015 Honda CR-V was blowing hot air and making noise when the A/C was on. The Compressor and Expansion valve needed replacement due to metal debris in the system. I rarely write reviews, but I felt it would be wrong not to appreciate Radman for their service, especially after what I went through before finding them. I’m writing this one month after the repair because I wanted to test my A/C on multiple long trips before recommending them. One thing I learned from this experience is that many mechanics know how to replace parts, but very *few follow the right procedures* and perform the proper checks. I initially went for a cheaper repair at a local mechanic. The problem came back, and afterward he didn’t seem to know what to do next. I found Radman through Google reviews without any personal recommendation, so I was taking a chance. They properly diagnosed the issue, explained everything clearly before starting the work, didn’t exaggerate the problem, and charged me a reasonable price. A/C issues can be complicated but they answered all my questions and I honestly haven’t had such a good and detailed conversation with a mechanic in the GTA about an A/C problem. Their knowledge and experience with A/C systems really stood out. I also had a catalytic converter issue. Another mechanic simply recommended replacing it, which would have cost at least $2,000. Radman explained that considering the age and condition of my 2015 CR-V, such an expensive replacement might not make sense. They gave me the replacement cost but also suggested trying Cataclean first. I tried it, and so far I haven’t had any issues. After a month and several long trips, my A/C is still working well. It’s rare to find this combination of knowledge, transparency, and honesty. Thank you, Radman, for the knowledgeable and honest service. I genuinely appreciate it.

I fix my cars myself but I always go to Radman for AC work. Been coming here for years and they do great work and are fairly priced. The guys are honest and reliable. Very clean waiting room too!

Finding a mechanic who actually understands EVs and is completely trustworthy is hard to come by, but ⁠Radman Repair is excellent. The service was top-notch, they explained everything to me with so much patience, and the overall experience was a 10/10. 100% recommended!
