Chrysler 31TH/41TE Transmission Service Manual – Factory Specs You Can Trust

I’ve lost count of how many times a junkyard transmission went south because some guy guessed the band adjustment. That’s exactly why this manual exists. At 86 pages, it’s not a coffee table book. It’s the only document Chrysler ever authorized for their 31TH three-speed and 41TE four-speed transaxles. If you’re working on a late-80s to mid-90s front-drive Chrysler product — minivan, sedan, coupe — this is the file you print out and smear with ATF.

What’s Inside This Manual?

You get the full factory diagnostic flow, torque converter clutch solenoid tests, and the step-by-step overhaul sequence. The manual breaks down each subassembly: oil pump, valve body, planetary gearset, and final drive. Special tools are listed by Chrysler part number — no guesswork on what puller fits the output shaft. Every torque value is stated in foot-pounds, and the clearance checks use inch-pounds for the small stuff. Page 41 has the clutch pack clearance specs; don’t skip that page unless you want a slipping second gear.

Does This Manual Cover the Valve Body?

It devotes an entire section to the valve body. You get the spring identification chart, check ball locations, and separator plate bore sizes. No diagrams that look like they were traced from a napkin. The manual also includes the shift speed chart, line pressure test ports, and governor pressure curve. If your 41TE is hunting gears, those pressure tap readings on page 62 will tell you if the problem is hydraulic or electronic.

Torque Specs and Fluid Capacities

Transmission overhaul lives or dies on torque. The factory manual lists every fastener — from the bell housing bolts (55 ft-lbs) to the valve body bolts (105 in-lbs). Fluid capacity for the 31TH is 4.8 quarts dry, 3.2 quarts on a filter change. For the 41TE, dry fill is 9.0 quarts. ATF+3 or ATF+4 only. If you use Dexron, you’re rebuilding again in 10,000 miles. Get the right spec from page 28.

3 Reasons to Choose OEM Documentation

One: aftermarket manuals compress step sequences and leave out the diagnostic trees. Two: they often substitute “typical” torque values that don’t match a 31TH’s aluminum case — stripped threads follow. Three: only OEM documents include TSB updates and in-process inspection points. This 86-page manual came from the Chrysler technical library, not a scan of a photocopy. It’s the same binder that dealers used when these cars were current.

Wiring and Electronics: Engine Override and Solenoid Testing

The 41TE is electronically controlled, and this manual covers every connector pinout. Need to test the TCC solenoid resistance? 20–30 ohms. The pressure control solenoid? 2.5–4.5 ohms. The manual also covers the TCU diagnostic modes, including the flashing LED sequence for trouble codes. If you’re swapping a 31TH into a vehicle that originally had a 41TE, the manual’s wiring diagrams show how to adapt the lockup circuit.

FAQ: Common Questions About This Manual

Does this manual include the torque converter specifications?

Yes. Page 38 has the converter end play limits and the breakaway torque test procedure.

Will this manual help me diagnose a no-shift condition in a 1994 Dodge Caravan?

Absolutely. The manual starts with a symptom-based diagnostic chart. For a no-shift, it tells you to check line pressure at the port on the governor cover, then test the shift solenoid resistances. The wiring color codes match the factory harness — no translation needed. It also includes the shift linkage adjustment procedure that most aftermarket guides omit, which is often the real problem on high-mileage vans.

Can I use this manual if I’ve never rebuilt a transmission before?

You can, but you should be comfortable with precision measuring tools and have the special tools list ready. This isn’t a training course; it’s a reference. The manual assumes you know how to use a dial indicator and a torque wrench.

Does the manual cover the 31TH and 41TE in the same document?

Yes, 86 pages cover both transmissions side by side. Differences in clutch count, valve body type, and electronic controls are noted at each step.

Source Authenticity: OEM vs. Aftermarket

I’ve seen aftermarket “service manuals” that copy the torque specs from a Haynes and call it a day. Then they wonder why a pump bolt backs out at 70 mph. This manual is the original Chrysler document, digitized from the factory binder. The page numbers, part references, and illustrations are exactly what you’d get from a dealer parts counter. Compare that to a generic PDF that uses “typical” values — you’re taking a risk every time you apply those numbers. OEM documentation is the only insurance you can buy against a comeback job.

If you want to understand the fundamentals of Internal Combustion Engine or the broader Automotive Industry Overview, those are separate topics. This manual is about getting the transmission right, down to the last Belleville spring.
