What Makes Multnomah Automotive the Right Choice for Transmission Replacement?
Transmission problems rarely improve on their own. You may first notice delayed shifts, slipping gears, or unusual sounds, but these symptoms often point to wear that’s happening inside the transmission. In some situations, repairs can solve the problem. When internal damage is too extensive, however, replacing the transmission is often the safest and most dependable way to restore your vehicle’s performance.
Â
Our technicians carefully inspect the transmission, evaluate its overall condition, and explain your options before recommending a replacement. If transmission replacement is the best long-term solution, we perform the work with quality components, careful installation, and attention to every detail. Multnomah Automotive’s goal is simple: help you leave with a vehicle that shifts smoothly and performs the way it should.

Common Signs Your Transmission May Be Failing
Addressing these problems early can help prevent additional damage throughout the drivetrain. Watch for these warning signs before a minor issue becomes a major breakdown:
Grinding, humming, or whining noises
When a vehicle is exhibiting grinding, humming, and/or whining noises it may indicate internal transmission wear, damage, or component failure. Potential causes include worn or damaged gears, bearings, shafts, planetary gearsets, or other internal transmission components, as well as low, contaminated, or deteriorated transmission fluid resulting in inadequate lubrication. These conditions can create abnormal noises that may vary with vehicle speed, engine RPM, acceleration, deceleration, or gear selection. If the noise is originating from significant internal transmission damage or wear, continued operation may result in further component deterioration and transmission failure. Due to the potential extent of internal damage and the need to restore proper and reliable transmission operation, transmission replacement may be necessary.
Vehicle hesitates before shifting gears
This might indicate an internal transmission concern or loss of proper hydraulic control. Potential causes include worn clutch packs, bands, or other internal components; malfunctioning shift solenoids or valve body components; low or deteriorated transmission fluid; or inadequate hydraulic pressure needed to apply the selected gear. These conditions can cause delayed gear engagement, shift hesitation, inconsistent shift timing, and increased engine RPM before the transmission completes the shift. If the hesitation is the result of significant internal wear, damage, or continued transmission deterioration, transmission replacement may be necessary to restore proper shifting performance, drivability, and reliable vehicle operation.
Vehicle struggles to move into gear
When the vehicle is experiencing difficulty moving into gear, it may indicate an internal transmission malfunction or loss of proper hydraulic control. Potential causes include worn or damaged clutch packs, bands, gears, or other internal components; malfunctioning shift solenoids or valve body components; low or deteriorated transmission fluid; or inadequate hydraulic pressure needed to engage the selected gear. These conditions can cause delayed or incomplete gear engagement, hesitation, harsh engagement, or a failure to transfer engine power to the drive wheels. If the condition is the result of significant internal transmission wear or damage, transmission replacement may be necessary to restore proper gear engagement, drivability, and reliable vehicle operation.
Burning odor after driving
This may indicate excessive transmission heat, fluid deterioration, or internal component wear. Potential causes include overheated or degraded transmission fluid, slipping or worn clutch packs and bands, excessive internal friction, or inadequate lubrication caused by low fluid levels. These conditions can generate excessive heat and cause the transmission fluid and internal components to deteriorate, potentially resulting in additional damage to gears, bearings, seals, and other transmission components. If the burning odor is associated with significant internal transmission wear, overheating, or damage, transmission replacement may be necessary to correct the underlying condition, restore reliable operation, and prevent further transmission deterioration.
Transmission fluid leaking beneath the vehicle
If a vehicle is exhibiting transmission fluid leakage beneath the vehicle, it may indicate deteriorated seals, gaskets, O-rings, axle seals, or damage to the transmission case, pan, or other transmission components. Continued fluid loss can result in a low transmission fluid level, causing inadequate lubrication, reduced hydraulic pressure, overheating, abnormal shifting, and accelerated internal wear. If the leak has contributed to significant internal transmission damage or if the source of the leak involves damaged transmission components or housing, replacing individual seals or repairing the leak may not fully correct the underlying condition. Due to the potential for continued fluid loss and associated internal damage, transmission replacement may be necessary to restore proper fluid containment, performance, and reliable vehicle operation.
Gears slip unexpectedly while driving
This may indicate internal transmission wear or failure. Potential causes include worn or damaged clutch packs, bands, gears, or other internal components, as well as low or deteriorated transmission fluid causing inadequate hydraulic pressure and lubrication. A malfunctioning valve body or shift solenoids may also prevent the transmission from maintaining proper gear engagement. These conditions can cause the transmission to unexpectedly disengage or shift out of the selected gear, resulting in increased engine RPM, reduced acceleration, hesitation, or inconsistent power delivery. If the slipping is caused by significant internal transmission wear or damage, transmission replacement may be necessary to restore proper gear engagement, drivability, and reliable vehicle operation.
Transmission warning light appears
This may be an indication that the vehicle’s transmission control system has detected a fault that may affect transmission operation or performance. Potential causes include internal transmission wear or damage, malfunctioning shift solenoids, valve body concerns, abnormal hydraulic pressure, sensor failures, or improper gear engagement. These conditions can result in shifting problems, slipping, delayed engagement, or other drivability concerns and may indicate that the transmission is not operating within its intended parameters. If diagnostic findings confirm significant internal transmission wear or damage, transmission replacement may be necessary to address the underlying condition, restore proper transmission function, and ensure reliable vehicle operation.
Poor acceleration despite higher engine RPMs
This could indicate that the transmission is not effectively transferring engine power to the drive wheels. Potential causes include slipping or worn clutch packs, bands, gears, or other internal transmission components, as well as inadequate hydraulic pressure, malfunctioning shift solenoids or valve body components, or deteriorated transmission fluid. When the engine RPM increases without a corresponding increase in vehicle speed, it can indicate internal transmission slipping or loss of proper gear engagement. If the condition is caused by significant internal transmission wear or damage, transmission replacement may be necessary to restore proper power transfer, acceleration, drivability, and reliable vehicle operation.

I had a really great experience here. Service was friendly and explained everything clearly and thoroughly. They also always maintained good communication throughout and the service was timely. I definitely see myself as a repeat customer.
They are the best!!! They could’ve charged an arm and a leg, but didn’t. They are integral, and good people. I’m a teacher, and we had a hard week at home. Mike’s genuineness, and integrity, were very timely, and appreciated. We will go to the shop again and again.
Staff was incredibly friendly and went above and beyond to make sure I was taken care of, work was quality and efficient. Will be returning my business here going forward!
This auto shop was great! They were so nice and helpful in everything they did. They diagnosed my problem quickly and replaced my battery very fast. Very inexpensive for the job performed and gave me quite a discount! Choose these guys they are the way to go!
I have been going to Multnomah Automotive for all my car repair needs. Every time I have been there, I have received stellar customer service. I could not have asked for a better Auto Repair shop. Thank You Jason!
During the last year I have taken my Dodge to Multnomah Automotive for both a major engine repair and a standard oil change. I felt respected and cared for both times and highly recommend this friendly neighborhood shop.

Great shop. Knowledgeable, trustworthy, kind staff. Fixed my car and gave helpful feedback on the things to keep an eye on. I will use them again and would recommend this shop to others.
Had my oil changed and transmission flushed. They were very helpful and up front, easy to work with, and completed services in a timely fashion. I will definitely be bringing my car back to Jason and team.
Amazing service and great management. Jason was awesome and quickly found the issue in my tire. I was in and out in about 10 minutes and for only $20. 10/10 auto shop experience
Had my starter go out. They were able to diagnose and replace within two days despite being extremely busy. They also provided a full inspection without being pushy or trying to upsale. Good honest work. Thanks!
Definitely recommend Multnomah Automotive for those searching for local auto care needs. They are friendly, honest, communicative, and work til they find a solution for the problem. Very happy to have them around for our ever-evolving car problems. Thank you!
