Predictika · Allison 3000 and 4000 Series transmission orders

An AI sales agent's transmission order, checked before it goes out

An AI sales agent prepares an order of Allison 3000 or 4000 Series automatic transmissions for a vehicle builder: the model and vocation, the engine's power, torque and speeds, vehicle weights, power takeoffs, output retarder, oil sump and torque converter. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published Allison Vocational Model Guide and returns a verdict, every reason and the figures it computed.

Scope: Allison 3000 and 4000 Series base models in Highway (HS), Motorhome (MH) and Truck RV (TRV) vocations: engine ratings, SEM torque limiting, weights, engine speeds, PTO, retarder, oil sump, torque converter. See everything this validator covers

This validator models an order of Allison 3000 or 4000 Series transmissions from the published Vocational Model Guide (2017), not just the scenarios shown below.

  • Ratings and weights — the maximum engine power and torque for each model and vocation, the higher torque rating that needs SEM torque limiting, and the gross vehicle and combination weights the guide lists. Power or torque above the rating is blocked; torque above the base rating without torque limiting is blocked, and with it needs a person to confirm.
  • Engine speeds and PTO — the governed engine speed range for each model, the 500 to 800 rpm idle range, the two PTO positions, the PTO torque each drive gear allows, the 600 rpm idle required when dual PTOs run together, and that PTOs are not available on HS models.
  • Options and stated figures — the oil sump (deep only on HS), the output retarder capacity levels offered on each model, which torque converters each model lists, and a stated first-gear ratio or dry weight that does not match the chosen configuration.

Any order of the 3000 or 4000 in these three vocations that touches these rules is in scope — not only the scenarios pictured here. Not covered: prices (Allison publishes none, so this page shows no price build-up), other models and vocations (such as 3500, 4500, 1000 and 2000 Series, or the 4000 in other vocation packages), turbine torque limits, gear-by-gear torque limits, and vehicle fitting or installation.

Where rules-based CPQ gets it wrong
Click to expand
    
Our assessment of what a typical rules-based CPQ (product rules, price rules and validation rules, as in Salesforce CPQ) does with the same cases. It is a judgment about effort and reliability, not a claim that nothing can be built.

    
What the validator caughtTypical rules-based CPQPredictika
Limits that depend on model and vocation togetherOnly with workarounds
Maximum power, torque and weight differ for each of six model and vocation pairs, so a rules-based CPQ needs a table or a rule per pair, and every guide update means editing them.		Model, vocation and the engine figures arrive in one request and are compared with that pair's listed ratings on every call.
Options that exist only for some modelsOnly with care
Retarder capacity levels, torque converters and the sump depth depend on the model and vocation, so a rule must read two or three fields at once.		The choices are checked together on every call.
A higher rating that needs another choiceOnly with care
The higher torque rating is allowed only with SEM torque limiting, which is a separate option elsewhere in the order.		The torque, the rating and the torque-limiting choice are compared on every call; the torque-limited case comes back as a needs-approval finding.
Figures the order states itselfOnly with care
A stated first-gear ratio or dry weight is free entry; a rule can compare it only after the right value is looked up from the model, PTO and retarder.		The expected figures are computed and compared with the stated ones on every call.
Every problem returned in one answerOnly with workarounds
Rules tend to fire as the order is saved or a step is completed, so a person often fixes one error and meets the next.		All findings come back together, whatever order the choices arrived in.

  

  

    
What this validator catches: findings from its test cases

Every rule is checked on every call, in any order the choices arrive; one problem never hides another. Blocking findings stop the quote; approval findings need a person to sign off; everything else is computed.

    
1An engine power of 601 hp is above the 600 hp maximum input power of the chosen model and vocation.
2An engine torque of 1851 lb-ft is above the 1850 lb-ft maximum input torque of the chosen model and vocation.
3A gross vehicle weight of 52001 lb is above the 52000 lb maximum for the chosen model and vocation.
4A gross combination weight of 72001 lb is above the 72000 lb maximum for the chosen model and vocation.

11An engine torque of 1250 lb-ft is above the 1100 lb-ft base rating and relies on the SEM torque-limited rating, which Allison lists for gears three through six only (on the 3000 HS it also requires Allison engine-transmission combination approval); a person should confirm.
12An engine torque of 1250 lb-ft is above the 1100 lb-ft rating without torque limiting; the higher rating requires SEM (Shift Energy Management) engine controls with torque limiting.
13A gross vehicle weight of 80001 lb is above the 80000 lb maximum for the chosen model and vocation.
14An engine torque of 1951 lb-ft is above the 1950 lb-ft maximum input torque of the chosen model and vocation.

The text of the narrated walkthrough, step by step.

    
    
      
  1. Welcome to a demo of Predictika's Validator. An AI sales agent prepares an order of Allison 3000 or 4000 Series automatic transmissions for a vehicle builder: the model and vocation, the engine's power, torque and speeds, and more. Before it goes out, the agent sends it to Predictika, which checks it against a declarative model of the published Allison Vocational Model Guide and returns a verdict, every reason and the figures it computed.
    2. 
      
  2. I will start with the first request by the agent.
    3. 
      
  3. The agent says. Please place an order of 8 Allison 4000 Series transmissions for Harborview Truck Bodies, in the Truck RV (TRV) vocation. The order states a dry weight of 893 lb. The rest of the request is on screen.
    4. 
      
  4. Before it goes out, the agent calls the validator.
    5. 
      
  5. Blocked, with three findings, all in one answer. A gross vehicle weight of 55000 lb is above the 52000 lb maximum for the chosen model and vocation. A PTO load of 1300 lb-ft is above the 1175 lb-ft drive gear rating for this number of PTOs. A minimum idle speed of 600 rpm is required when dual PTOs are used simultaneously; the engine idles at 550 rpm.
    6. 
      
  6. The validator returned three blocking findings in one answer. A check that reads one field at a time would pass most of this; it shows only when the choices in the quote are checked against each other.
    7. 
      
  7. What this shows: for a higher rating that needs another choice, a rules-based CPQ is error-prone for this.
    8. 
      
  8. Now the agent resubmits.
    9. 
      
  9. The corrected request. It changes the PTO load to 1,175 and the gross vehicle weight to 52,000 lb.
    10. 
      
  10. It calls the validator again.
    11. 
      
  11. Still blocked, with one finding, all in one answer. A minimum idle speed of 600 rpm is required when dual PTOs are used simultaneously; the engine idles at 550 rpm.
    12. 
      
  12. Two findings cleared. Still blocking: dual PTO needs 600 rpm idle.
    13. 
      
  13. The agent resubmits once more.
    14. 
      
  14. The revised request. It changes the idle speed to 600 rpm.
    15. 
      
  15. It calls the validator once more.
    16. 
      
  16. This time the validator clears it.
    17. 
      
  17. The earlier finding is cleared, and the validator's figure matches the quote.
    18. 
      
  18. Three problems caught in one call, fixed in two passes, and a clean quote. That is the value of Predictika's validator: catching mistakes before they reach the customer. Now you can try the other scenarios yourself.
    19.
