I’ve been looking for a reliable 4 speed Saginaw myself! I found a few places online that specialize in them, like RockAuto and Summit Racing. Has anyone used them?

I’ve had luck with a local rebuild shop. They were honest and the Saginaw works great now. Sometimes, local is better than online!

I’ve been wary of online suppliers. Anyone had experience with eBay sellers? It’s a gamble, but you can snag a deal!

I bought a used one on eBay last year and it was a bust. I wouldn’t recommend it unless you can inspect it first.

I recently went with a rebuilt unit from a place called Transmissions and More. They offered a warranty, which gave me peace of mind.

It was around $1,200, but that included installation. It’s been running smooth since then!

LOL! True! Last time, I found a vintage steering wheel that way. I’ll give it a shot for the transmission too!

For a new unit, I suggest calling local dealerships. It might be pricier, but you get OEM quality.

That’s true, but what about the wait time? I’ve heard dealerships can take ages!

That can definitely be a downside. I’ve waited weeks for parts before. It’s all about what you prioritize: speed or reliability.

Sounds like a good plan! Just remember, the Saginaw is great as is. Don’t fix what ain’t broke!

Absolutely! Misalignment can lead to difficult shifting. Make sure to check your input shaft before installation, that really helped me avoid headaches.

Yes, having the right tools is crucial! I recommend getting a torque wrench and a good set of line wrenches for the fittings. Did you guys also consider the bellhousing alignment?

That’s a great point! Getting that right is essential. If it’s even slightly off, the transmission won’t shift properly.
