A transmission going out rarely fails all at once — it warns you first. Slipping under load, grinding into gear, hard or missed shifts, a whine that wasn’t there last week. Catch it early and it’s often a repair. Ignore it and it’s a rebuild or a replacement and a truck down for days. J&A Fleet diagnoses and repairs heavy-duty transmissions the right way, with techs trained on Eaton and Allison units, so you know what you’re actually dealing with before you spend a dollar.
SIGNS YOUR TRANSMISSION NEEDS ATTENTION
- Slipping or losing power under load
- Grinding, clunking, or jumping out of gear
- Hard shifts, missed gears, or a stiff stick
- Whining, humming, or growling that changes with gear
- Leaks, low or burnt-smelling fluid
- Stuck in gear or won’t go into gear at all
WHAT WE DO
- Full diagnosis — road test, fluid check, and inspection to find the real cause
- Clutch, linkage, and shifter repairs
- Seal and leak repairs
- Component repair and replacement
- Rebuilds and full transmission replacement when it’s the right call
- Driveline and related repairs that often ride along with transmission problems
HONEST DIAGNOSIS FIRST
Here’s where shops cost you money: quoting a rebuild when the problem is a clutch or a linkage adjustment. We diagnose to the root and tell you straight — repair, rebuild, or replace, and why. If a lower-cost fix will hold, that’s what we’ll recommend. If the unit’s done, we’ll tell you that too, instead of selling you a patch that strands you next month.
DONE RIGHT THE FIRST TIME
Eaton and Allison trained techs, quality parts, and a road test to confirm the fix before the truck leaves. Transmission work is too expensive to do twice — so we do it once, right.
PRICING YOU CAN SEE COMING
You’ll hear our hourly rate, our minimum, and any surcharges up front. Mobile road service is billed port to port, and the price only changes if the job changes. No surprise line items on a big repair.
MOBILE OR IN THE SHOP
Diagnostics and smaller repairs can often be handled on site. For rebuilds and replacements that need the bay, we don’t run tow trucks, but we work with a network of tow companies and get the best rates to bring your truck in and finish the job here.
WHERE WE WORK
Transmission repair across Morris, Aurora, Joliet, New Lenox, Rockdale, Gardner, and the surrounding I-80 / I-55 corridor.
WHY J&A Fleet Maintenance
Founded by a diesel tech turned fleet manager who got tired of watching shops sell labor instead of solving problems. With us you get honest diagnosis, fair upfront pricing, certified techs, and transmission work that holds up. We treat your downtime like it’s costing us money too — because keeping you running is the job.
A FEW QUICK ANSWERS
Is it a rebuild or just a repair?
We won’t know until we diagnose it — and we’ll tell you straight either way, instead of defaulting to the most expensive option.
Can you come to me?
Diagnosis and smaller fixes, yes. Bigger jobs come to the shop; we’ll line up the tow at the best rate.
