Chrysler A404, A413, A415, A470 Service Manual – Factory Specs for the TorqueFlite Transaxle

You have a Chrysler front-drive transaxle on the bench. A404, A413, A415, or A470 – they all look similar from the outside, but swap one valve body spring and you’ll chase a shift problem for days. I’ve seen guys rebuild one of these with a generic manual, then wonder why the differential whines or the band snaps. The answer is always the same: you need the factory Chrysler A404, A413, A415, A470 Service Manual. That 95-page binder is exactly what Chrysler handed to their own dealer techs. It’s the only document that gives you the correct seven-digit part number off the oil pan flange and tells you which internal parts differ by vehicle/engine combo.

Transaxle Overhaul: Sections You’ll Actually Use

The manual breaks down into nine indexed chapters starting with General Information (page 4) and ending with Bearing Service (page 76). Right off the bat, the Diagnosis & Test section on page 7 shows you how to use line pressure taps and stall tests without guessing. I’ve pulled more than one valve body because a tech didn’t bother with the pressure chart on page 14. That’s wasted time. The Maintenance & Adjustments chapter (page 17) covers band adjustments and throttle linkage – critical for the A470 that tends to flare on the 2-3 shift if the kickdown isn’t set right. Service Out of Vehicle (page 21) walks you through the teardown, including the special tool L-4550-A for removing the differential bearing retainer. Skipping that tool? You’ll crack the housing. Plain and simple.

Oil Diagrams and Bearing Adjustments – Why Factory Data Matters

Page 42 starts the Oil Diagrams. These are hydraulic circuit maps – not aftermarket cartoons. They show exactly which clutch pack feeds from which passage when the governor shifts. If you’re rebuilding an A413 with a stuck shift valve, the oil diagram on page 48 tells you the feed path for the front clutch. Compare that to a third-party manual that might swap the A415 and A470 circuits. I’ve seen it happen. Then Bearing Adjustments (page 64) gives you the preload specs in inch-pounds. The differential carrier uses a collapsible spacer; the manual tells you the rotational torque (8-12 in-lbs for a new bearing) and the tool required. Ignore that and you’ll end up with a whining differential that comes back under warranty.

Specifications and Tools – Page 69 and Page 73

Page 69 lists every torque value: converter-to-drive-plate bolts (55 ft-lbs), valve body bolts (105 in-lbs), and differential cover bolts (20 ft-lbs). No “tighten securely” nonsense. These are OEM foot-pounds. The Tools chapter (page 73) shows the official Chrysler tool numbers – like C-4013 for the torque converter clutch remover. I keep a printed copy of that page in my toolbox because aftermarket tools don’t always fit the A470’s deeper bell housing. The Bearing Service section (page 76) wraps up with bearing interchange numbers and where to apply thread locker. All 95 pages are there for one reason: to get the transaxle back on the road without a second teardown.

3 Systems Within One Housing – Keeping Them Separate

The manual stresses that the differential sump is separate from the transaxle sump. Fill the differential to 1/8 to 3/8 inch below the fill hole. Overfill it and you get foam; underfill and the pinion bearings starve. That detail is in the General Information chapter. The transfer shaft centerline has its own governor and parking sprag. The main centerline holds the valve body. Three separate lube circuits, one casting. The factory manual is the only place you’ll see the exact fluid capacities: ATF+3 for the transaxle side, and 80W-90 for the differential – yes, two different fluids in the same housing. Miss that and you’ll burn up the differential in 5,000 miles.

Source Validity: OEM Beat Aftermarket Every Time

This is a direct reproduction of the original factory service manual distributed by Automatic Transmission Service Group under license from Chrysler Corporation. The index matches the factory TOC: Diagnosis & Test, Maintenance & Adjustments, Oil Diagrams, Bearing Adjustments – all there. Aftermarket manuals often combine the A404 and A470 into one generic procedure, but this document keeps them separate because the internal parts (like the reaction shaft support) are different. I’ve used ATSG manuals for years; they’re the same ones the factory training centers used. When you buy this, you get the 95 pages as they were printed, including the torque specs and the tool listings. No condensed “quick reference” that leaves out the low-drum clutch clearance measurements.

FAQ – Frequently Asked Questions

Does this manual cover both the A404 and the A470?

Yes. The index lists all four models: A404, A413, A415, and A470. The General Information chapter explains that the identification markings are in Diagnosis and Tests, and internal parts differ by seven-digit part number. You get the procedures for each model.

What torque values are listed?

The Specifications chapter on page 69 provides foot-pounds and inch-pounds for every fastener mentioned in the rebuild. Converter bolts, valve body bolts, differential cover bolts – all factory OEM.

Are the oil diagrams clear enough for a home mechanic?

They are schematic line drawings. If you can trace a hydraulic circuit in a standard automatic transmission, you’ll follow these. The manual assumes you understand basic valve body function. For someone learning automatic transmissions, pair this manual with a good explanation of manual transmission fundamentals to understand the differences.

Can I reuse the old torque converter bolts according to the manual?

The manual does not explicitly state reuse recommendations, but it lists the torque spec. I always replace them – they stretch. Use the tool chart on page 73 to get the correct socket size. For more on bolt reuse, see any Manual Transmission supplement.

Look, I’ve been doing this since before most of you were born. A good transmission rebuild starts with the right specs in your hand, not a generic PDF you found on a forum. The Chrysler A404, A413, A415, A470 Service Manual is the factory blueprint for these transaxles. You want it on your bench, not ten clicks away on a tablet.
