Chrysler A-500 1992 Technical Manual – What Your Transmission Rebuild Needs

If you’ve ever had a transmission rebuild go sideways because you guessed at clutch pack clearances, you know the frustration. This isn’t a job where “close enough” works. The A-500 is a hybrid of the A-998 three-speed with an overdrive section, and Chrysler introduced it in 1988. The Chrysler A-500 1992 Technical Manual from ATSG gives you the factory procedures – not some generic aftermarket interpretation. 88 pages of specs that came straight from the engineers. I’ve seen too many guys skip the cooler flow check and blame the transmission when it fails six months later. This manual covers exactly that on page 87, with tech bulletins for overdrive clutch and planetary failure.

What’s Inside the A-500 Technical Manual

The book starts with an introduction to the A-500, explaining how it evolved from the A-998/999 TorqueFlite family – not a Manual Transmission in any sense. It then breaks down power flow and parts changes for the front section, the overdrive unit, and even includes details on the New Process 231 transfer case. You’ll find the exact clutch plate count for the direct clutch pack: five or six lined plates depending on engine application. Get that wrong by one plate and your shim measurement will be off by more than 0.250 inch. That’s a reverse slip complaint waiting to happen. The manual gives you the dimensions for the two special tools needed to measure selective spacers – those dimensions are on page 88.

Does This Manual Cover the Overdrive Section?

Yes, and it’s the main reason you need this document. The overdrive unit is shared between the A-500 and A-518, but the clutch pack count differs. This manual walks you through the 3-4 shift, which is hydraulically controlled by governor pressure once the computer energizes the overdrive solenoid after the engine reaches operating temperature. Pages 69 and 70 show the measurement check procedure for the overdrive selective spacers. If you’re rebuilding one of these, that’s where you spend your time. The shift is not computer-controlled in the sense of shift timing – only the 3-4 upshift is enabled by coolant temperature input. The rest is pure hydraulics.

3 Critical Assembly Checks from the Factory

First: direct clutch pack thickness. Count the lined plates before you disassemble – write it down. Second: perform the oil cooler flow check. Disconnect the return line and run a hose into a bucket – if flow is restricted, replace the cooler. Third: check the overdrive shim measurement using the tools specified on page 88. I’ve seen guys skip the flow check and then wonder why the overdrive fails again. Chrysler’s own tech bulletins on pages 86 and 87 address those exact failures. Use them.

Check the Direct Clutch Pack Shim Before Reassembly

This is where aftermarket manuals fall apart. They tell you to reuse the old shim without confirming thickness. The ATSG manual gives you the factory method: stack the lined and steel plates, measure the pack height, then select the spacer from the chart. If you’ve swapped in a clutch drum from a different application, the selective spacer thickness changes. Page 69 shows the measurement steps. I can’t count the number of A-500 rebuilds I’ve had to redo because someone assumed the shim was correct. Don’t be that guy.

Transfer Case Coverage: New Process 231

Since the A-500 is common in 4×4 trucks – Dakotas, Ram vans – the manual includes information on the New Process 231 transfer case. You get the same factory-level detail: torque specs, seal replacement procedures, and bearing preload data. This isn’t a general guide; it’s specific to the combination found in Chrysler vehicles. If you’re working on a 4×4, having the transfer case data in the same document saves time flipping between separate manuals. It’s all here.

Source Authenticity – OEM vs Aftermarket

This is a factory-authorized technical manual produced by ATSG with direct input from Chrysler Corporation. The illustrations and information in it were provided by Chrysler themselves. I’ve seen aftermarket versions that list generic torque values for “TorqueFlite” transmissions that don’t match the A-500 overdrive unit. Those manuals will get you into trouble. This one was printed in 1992 and contains the exact update information for the A-518 converter clutch introduction. The document is a scan of the original physical manual – no reprint errors, no missing pages. You get the full 88 pages including the tech bulletins at the end.

Is this manual suitable for a beginner DIY mechanic?

Yes, if you’ve done basic transmission work before. The writing assumes you know how to handle a torque wrench and read a dial indicator. Beginners should start by reading the introduction and the safety notes.

Does it include torque specifications for the valve body bolts?

Yes. Torque specs are listed throughout for all major fastener groups.

What about wiring diagrams – does this manual have them?

No. This is a mechanical/ hydraulic technical manual. The A-500 is not computer-controlled in the modern sense; the only electrical component is the overdrive solenoid. The manual covers that solenoid and its wiring circuit, but there are no full vehicle wiring diagrams.

Can I use this manual for an A-518 transmission?

Partially. The overdrive section is identical, but the front section (three-speed) is different – the A-518 uses a 727, not the 904/999. The manual notes differences where applicable, especially for the direct clutch pack plate count. For a complete A-518 rebuild you need the specific A-518 manual as well. This one covers the A-500 and gives overlap info for the overdrive unit.

When you download the Factory Manual, you’re getting the same document that trained technicians at Chrysler dealerships used. No guesswork, no relying on forum posts that may have mixed up the shim thickness. The data is verified. If you’re rebuilding an A-500, this is your blueprint. [Manual Transmission]? Not needed – you’ve got the right one here.
