Warning Signs of a Manual Transmission Repair

Your manual transmission is typically very dependable. Manual transmissions do require to be serviced at intervals. Reference your owners manual for maintenance recommendations. Modern cars are made with manual transmissions. Nothing is full proof. As sophisticated as these modern transmissions can be, errors can make those gearshifts considerably less smooth. When a manual transmission fails, you might notice some strange sounds or vibrations when something goes awry with your vehicle’s transmission. In other situations, your transmission might shift gears in unpredictable ways, resulting in uneven speeds and inconsistencies while driving. Your car may sound like it’s trying to go 100 miles per hour when it’s only traveling at 50, this is known as a clutch slipping in most cases. Additionally, there might be a few seconds delay when you shift each gear.

You may also noise a grind during the transition of a shift.

This is typically known as failed synchronizer. Synchronizers are a part inside your manual transmission. Synchronizers are what allows a gear selection to made smoothly. Worn or damaged synchronizers can lead to further damage if the synchronizers are pushed to far. While some of these problems might seem negligible in the moment, ignoring such issues could make the situation worse, decreasing the life of your manual transmission over time and increasing the costs to repair.

How Manual Transmissions Work

A manual transmissions internal rotating assemblies have many moving parts. Gears, bearings and synchronizers make up just a portion of the pieces inside a manual transmission. A manual transmissions gears are machined in a way that allows each gears tooth surface to mate very closely to each other. Each manual transmissions gears, has a certain amount of teeth. The combined amount of teeth on a mating set of gears determines the manual transmissions gears ratio.

When shifting a manual transmission, it takes multiple gears inside the manual transmission to get the end result.

Bearings support gears and shafts and allow the manual transmissions gears and shafts to turn smoothly. Synchronizers in a manual transmission are designed to stop the gears from spinning. A manual transmissions synchronizers also align the slider to a gear. When the gears stop spinning inside the manual transmission, the slider, which is moved when you shift by the shift fork inside the manual transmission, locks additional teeth on the gears side (whatever gear your shifting into). The manual transmissions gears assemble is now locked into the gears side teeth and you have completed your shift. When synchronizers fail, you may experience grinding or noises and a sensation in your manual transmissions shifter handle during the transmissions shift transition to the next gears selection.

These guys are SO great. Great job and a great price! My family and I (and even friends that I referred) drive an hour to come to them. They do great work and have excellent customer care! Even when it was closing time they were so kind and helpful, making sure I understood and was satisfied with everything, instead of just rushing me out the door. 100% recommend them!

Hello, had the transmission in my 66 Ford Fairlane rebuilt in October 2021. Nearly 2 years later still working great no leaks shifts just as nice as it did when I picked it up. Great customer service after the rebuild would totally recommend.


Take your car here. If you have any transmission issues this is the absolute best transmission shop you will find in Denver. My cars transmission lost reverse gear, and had a slew of other issues going on internally that I didn’t even know about, requiring a complete transmission rebuild. Devin was absolutely phenomenal, and let me know everything that was happening during the entire service. These guys absolutely stand by their word, and work. The diagnostic is only $90. With 250k miles, I have a rebuilt engine with 50k miles on it, and now a new, rebuilt transmission. Flawless. Another 4×4 lives another day. Drives smoother than ever. Thank you guys!

Brought my 08 pontiac grand prix for a rebuild of the transmission, car was done within two days of dropping it off and the price quoted was correct and affordable (for a transmission rebuild) the shop is very professional and knowledgeable also friendly and don’t make you feel dumb or belittle you for asking questions. Also check back in with you on their work a week or two later. Would definitely return to these guys for any transmission work I’ll need on any of my vehicles and will always recommend them to friends, family and anyone needing work done. Thank you guys!!

I can not rave enough about thus place. Randy and his team are fast, friendly, and KNOW what they are doing! I had my clutch replaced here after being less than happy with another company doing it twice and blowing it both times in two years… This team is transparent and care about the quality of their work. If you need transmission work or your clutch replaced, this is your company. They made my Subaru ready for the road and I couldn’t be happier! 10/10 tldr: use this company and you will be a happy camper
