What We Do

Complete auto care,
from routine to complex

Whether it's an oil change or an engine overhaul, we bring the same attention to detail and commitment to quality.

01

Engine Repair & Diagnostics

Check engine light on? We use advanced diagnostic tools to pinpoint the issue fast — and explain exactly what's wrong before we touch a bolt.

02

Oil Changes & Maintenance

Regular maintenance is the best insurance against costly breakdowns. We follow manufacturer specs and keep you on schedule.

03

Brake Service

Spongy pedals, grinding noises, or vibration when you stop — don't ignore it. We inspect, repair, and replace brakes with precision.

04

Transmission Service

From fluid flushes to complete rebuilds, we handle transmissions for both automatic and manual vehicles with care and expertise.

05

Suspension & Steering

Rough rides, pulling to one side, or uneven tire wear — we diagnose and repair shocks, struts, control arms, and alignment issues.

06

Electrical Systems

Dead batteries, flickering lights, parasitic draws — automotive electronics are complex. We trace and fix electrical gremlins fast.

About Us

Built on
trust, not upsells

Custom Conversions started with a simple belief: every driver in New Milford deserves a mechanic who tells the truth — even when it's not what they want to hear.

We're not a franchise. We're not chasing volume. When you pull into our shop on Old State Road, you're getting hands-on expertise from people who actually care whether your car leaves our bay running better than it arrived.

Some jobs are quick. Some take time. But every job gets our full attention, a clear explanation, and a fair price — no surprises on the invoice, no unnecessary repairs.

Transparent pricing — no hidden fees
Certified, experienced technicians
Same-day service on most repairs
Warranty on parts and labor

What Our Customers Say

Trusted by
New Milford drivers

"I've been bringing my cars here for years. They never try to sell me things I don't need, and they always explain what's going on in a way I can actually understand. That's rare."

Local Driver New Milford, CT

"My brake lights went out on a Friday afternoon and I was worried. They got me in quickly, diagnosed the issue, and had me back on the road the same day. Honest, fast, and fair."

Local Driver New Milford, CT

"After a bad experience elsewhere, I was skeptical. Custom Conversions proved me wrong — they showed me exactly what was wrong, explained why, and the repair has held up perfectly."
