Is a specialist needed for an FD transmission rebuild?

Not sure if this is a dumb question, but I'll ask anyways:
My (manual) transmission has become more of a pain to use as time goes on. I want to get the thing fully rebuilt (synchros, bearings, the works).

If I needed an engine rebuilt, I'd of course send it to a rotary specialist. However, is there any need to hand the transmission over to a rotary-specialist shop or would any quality transmission shop be fine? Is there anything unique about the 5-speed that would make you think twice about dropping it off at your local transmission shop?

I had a comprehensive rebuild on mine about two years ago. Just took it to a local shop that specialized in transmissions and differentials. New brass, bearings etc. Don’t think there’s anything special about them but he did say that he wasn’t able to get everything for it through his normal suppliers. I hooked him up with Ray Crowe for what he couldn’t find. It was a shop that does mostly domestics so that may have been part of it.

I wouldn't say specialist but with fewer and fewer cars being offered with true manual transmissions these days, many shops tend to focus on automatics. You do need some specialty tools, such as a super deep socket to go over the shaft and get the nuts off and some long pullers.

they need to be independent specialists. Most franchised dealerships do not bother with rebuilding. Cost effective labour proves better to yank and replace with a rebuilt (from a specialist) then rebuilding the trans on site. Unless you are GM. They enjoy giving a technician an unreasonable warranty time to rebuild a transmission.

I called my local mazda when my 5th gear / reverse syncro went out looking to rent or buy that socket. They said they cant get it.

“What if I brought in my transmission for a rebuild?”

”we would replace it not rebuild it”

luckily there are work arounds for both the sockst and the puller!

cylinder head to show just how long that socket is!

I would send mine to Jacks Transmisssions in Colorado springs if I needed it done. Tom93R1 just had his rebuilt thru them and jack knows his stuff.

I took my FD trans to my local transmission shop and after he disassembled it and gave me the quote to rebuild it it was only a few hundred dollars less than a brand new unit from Mazda Motorsports.

So, that is another possibility.

in my case it was-
$1,900 for rebuild
Including
$1,000 labor
$600 bearings/synchros/etc kit
$300 new input and main shaft required on my trans due to bearing failure

^Ouch. Mine was only about $1200 with me R & R’ing the transmission. But then i didn’t need my shafts replaced. And if I would have gone new it’s likely shipping would have been more for me here in the Midwest.

Big thing here is find a shop that specializes in manual transmissions, does it all day long, and does a good job. There's nothing special about the FD transmission, it's a pretty regular transmission design.

I've done 5th gear synchro replacements myself, that isn't too hard to do yourself. Most other things can really benefit from someone who does it all day, every day.

Man! for that kind of scratch I could go for something like Pettit's offering here:
Blueprinted FD Transmission
Anyone have experience with that?

Could you shoot me a PM or reply who you went to? Are you satisfied with their work?

Xander - I rebuild all Mazda RWD 5 speeds including RX4, REPU, SA, FB, FC, TII, and FD. I currently have a listing on Seattle Craigslist for a REPU that is an example of my work. I'm retired so I have the time to build these transmissions as if they're going in my own car.

I got my 88 Turbo II transmission rebuilt a few years ago, which isn't that different from an FD trans. Basically, it's similar to the manual trans they used to offer in the Ford Explorer back in the 90s. It's not especially unique, but as this thread has mentioned, manuals in general are now a niche thing in the US so most shops are going to build autos.

To anyone doing this I’ll offer a small tip... when you drop the transmission mark the switches before you remove them to take the transmission into the shop. The 1-2 switch and reverse switch can be reinstalled in the wrong locations....and you can’t access them both once the transmissions reinstalled. Ask me how I know.

+1, Ford used the same basic transmission from the mid-80's into the early 90's, so like with the differentials, you're looking for an old Ford guy (they did a lot of differentials under warranty before they figured out that they are just clunky and whiny)
