About these figures
- 356,471 repair records = 56,471 in BayStacker’s searchable database + 300,000 off-site work orders the business reports holding.
- The off-site figure is one stated number, not counted records: it is not searched by the free lookup, does not change, and is not part of “today”.
- Every per-family figure on this page counts database records only.
- Figures as of Nov 3, 2026, 4:47 PM CST.
Full OS is $499 USD per location a month. 7-day free trial. A card is required when the trial starts and is first charged when the trial ends, unless you cancel before then. Founding shops get their history imported for them.
Moving from another system
Your repair history comes in as a CSV file, and we help you export it from the system you use today. Every import runs as a dry run first: nothing is written until you have checked it.
The real cost
You do not have a capacity problem. You have a rework problem.
Every comeback is labour you pay for twice, parts that are gone, a bay that cannot take the next job, and no extra revenue. The five ways a transmission shop bleeds:
- 01
Reworks and warranty comebacks
You pay twice. You bill once.
A failed or unfinished repair is duplicate labour, parts that are gone, a bay that cannot take the next job, and no extra revenue.
- 02
Inconsistent diagnosis and QC
The same failure, twice.
A wrong root cause, or a rebuild that does not match the last one, comes back as the same job with the same cost.
- 03
No one owns the comeback
A comeback with no name on it.
Cycle time and rework only mean something if they point at a job, a step, a part, or a person, and most shops cannot point.
- 04
Vehicles stuck in production
The bay is full. Nothing is leaving.
Diagnosis, parts, the build, the install, the test and the approval each hold a car when they stall, and the shop carries all of them.
- 05
The record is in five places
Five systems. One job.
Intake, status, the technician’s work, parts, warranty and money belong on the same job rather than on five screens that never agree.
The mechanism
Analysis A. Then the next test. Then a repair that stays closed.
2numbers
Completeness and confidence stay separate, so a confident-but-thin case never looks finished.
The next test is the gap that most moves them.
0invoices early
A managed job does not invoice, deliver or close until verification passes.
A comeback reopens the work order it came from.
1record
Intake, diagnosis, parts, the build, verification and money live on one case, so every question about a job has one place to look.
The case is the one place, start to finish.

The product · Transmission shop management software
Diagnosis is the centre. Everything else is the job around it.
BayStacker is transmission shop management software where the diagnosis case, shop floor, R&R queue, builder bench and ledger share one record from intake to final invoice.
Analysis A
A ranked hypothesis grounded in the case.
The complaint, the decoded VIN and the first finding go on the case. Analysis A returns a ranked hypothesis with the evidence behind it, measured against the transmission family and the shop’s own closed cases.
- A voice or typed complaint, gated on the VIN
- Ranked against the family and the shop’s own closed cases
- The evidence behind each hypothesis stays on the case

Comebacks
Catch the comeback before it leaves the shop.
Rework risk is computed from the evidence that is missing, the family’s history and this vehicle inside the case before delivery, while there is still time to run the test.
- Rework risk before anyone signs the ticket out
- The next test is the gap that most moves confidence
- Invoice, delivery and closeout wait on verification

The record
One transmission job lifecycle on one case.
The diagnosis case is the primary object. Work orders, R&R and bench labor, parts, teardown build sheets, core tracking, verification and the invoice are downstream of it, so a comeback, a stuck vehicle and a technician’s work all trace back to the same job.
- A stuck vehicle names the step that is holding it
- Paper tickets, group texts and parts notes become one case record
- A reading nobody took shows as missing, never as a guess

The golden path
Diagnosis first. The work order is downstream of it.
From the complaint to the build sheet, in the order the work happens, on the test shop’s two open repairs. Verification and the invoice come after, and not before.
If it comes back: Warranty rework reopens the work order it came from for the diagnostician, instead of starting a second one.
