GM THM 400 Transmission found in many 19691985 GM domestic vehicles. Covers assembly, disassembly, diagnosis, and troubleshooting.
⚠️ WARNING (California Proposition 65):
This product may contain chemicals known to the State of California to cause cancer,
birth defects, or other reproductive harm.
I really wanted to dive into the THM 400 TechTran manual, but it arrived with some pages torn and a few smudges. It was disappointing because I was excited to start my transmission project. I hope the next one is in better shape!

Solid resource, but some details missing
This manual has been helpful for servicing the THM 400, but I found a few areas where instructions could be clearer. The illustrations are nice, but could use more step-by-step guidance. Still, it's a good resource for what it covers!

Great manual for transmission service!
I bought the THM 400 TechTran manual for my dad who has been working on classic cars for years. The detailed illustrations really helped him understand the automatic transmission service process. He said it's a must-have for anyone serious about transmission work!
