@Aeromoto sold me a crate o' FiST a while back. 
Finished the install late last night, only had time to run it up the road a mile or so and back before I went in for my 5th shower in 2 days and collapsed. lol... Tonight I'll put the hood back on when @DRVIPER711 gets back in town (I took it off alone, but there's no way I'm getting it installed and aligned alone) and I'll check it over more thoroughly. I let it idle for about 15 minutes before I drove it, no fluid leaks I could see at the time but it definitely idles low now. It also fell on its face somewhat on acceleration, but a) that engine hasn't been run in over a year, most likely, and b) the battery was disconnected for several days, so I assume it needs to relearn a bunch of sensor inputs. I also have a Cobb tuner that I haven't used on it yet since I knew it was getting major surgery, lol- I don't know if installing the new tune will force it to reset some parameters anyway. So, good news, it runs with no CEL and no obvious major leaks. Bad news, the idle was low enough to flicker the lights (that did seem to improve after I drove it that short distance, so may just have needed to remap its throttle calibrations- I was so tired I didn't stick around in the parking lot to watch it idle) and it stumbles on acceleration, which could be a calibration issue or could be a boost leak somewhere, last time I had it apart to replace the clutch it had a slightly loose hose clamp on the charge pipe that I didn't notice until I was on the highway.

Oh, and I found axle seals at NAPA that met the dimensions perfectly, but aren't actually listed for the FiST- I figure it's better than not having a drivable car, and if it doesn't leak, great. If it does, I'll just get the right ones from the dealer 'eventually.'

I did manage to squeeze the whole engine and transmission assembly out and in without pulling the front end off, so that was nice- I had the hoist chain as short as I could get it and the lifting strap rigged to be very short as well. I lifted from the passenger side mount and a bolt I put through the bracket at the back of the valve cover on the driver's side, it doesn't have anything that bolts on there but it is a fairly sturdy bracket. I couldn't use a load leveler because of the height restriction imposed by the ceiling, but it juuuuust barely cleared with the front end up on jack stands.

So I don't have a great picture of it, but there is a black bracket on the driver's side rear of the cylinder head that has threaded holes and nothing attached to it, that's what I lifted the driver's side from. Passenger side i just looped the lifting strap around the mount since I was pulling that as well, I replaced both upper mounts with the considerably younger ones from the replacement engine and put on the black mount insert and ARP bolt for the passenger side.

I forgot, when I did the clutch a while back I put a magnetic plug in- this is what came out, along with some very pretty glittering fluid. Lol... the bearing noise suddenly went away while driving on the highway, which I took to be a very bad thing. looks like I was right. Anybody need a perfectly good 2014 ST transmission... housing? lol. I'll be selling the old engine and a bunch of other parts soon, but I'm not sure anybody wants to rebuild this transmission unless you're doing a complete race build with all new components. It DID shift just fine getting into the garage from the parking lot, but that was just reverse, first, and second gears.

Update, coil on cylinder 3 was intermittently failing to spark, likely it just wasn't seated all the way but I swapped on a known good one anyway and all is right with the world. Threw the OTS Cobb tune on it and I'm pretty happy with my work right now- waiting to make sure nothing shows up in the next week or so to make me doubt that. Lol
Hey guys I'm new here, I apologize if I'm posting in the wrong thread but it seems like there are some knowledgeable guys in here. I bought a 2015 Fiesta ST with a bad transmission and am not sure what the best replacement option is. I am looking for a stock replacement but don't want it to last at least another 100k miles. These guys have a used and a remanufactured one here, https://reman-transmission.com/transmissions/ford/fiesta/2015/ and for the price difference, I think I'm leaning towards remanufactured. Have you guys heard of this retailer or know of a better one? And if you have any thoughts on the whole used or remanufactured suggestions are welcome.
I don't have any advice about that, but you might have some luck posting in the transmission section here. https://www.fiestastforum.com/forums/transmission-drivetrain.87/
Do it right the first time* You will not regret it. this also gives you the opportunity to install a LSD also.

TL;DR is DO NOT SEND THEM MONEY.
Looking at their site, they have regular Fiesta 5 speed manuals, not the 6 speed for an ST. DO NOT SEND THEM ANY MONEY. I've dealt with them before- I sent an inquiry about a reman 6 speed, they told me they had one, sent me the info, I pointed out that it was a 5 speed, they assured me that was just mislabeled, I pointed out that the part number from the casting was a 5 speed, they told me they didn't have a 6 speed but had one used for $1200, super low mileage, shipped. They emailed me the specs on it with a stock number. I agreed, paid, and waited. And waited. And waited. I emailed asking for an update after 3 weeks, they said it was because covid slowed everything down but check back in 3 more weeks. Glad it's a second vehicle, I guess... more waiting. Nothing. I Google the stock number they sent on a hunch, it's just their prefix and then the auction listing on a used parts site for that exact transmission- same mileage and year, same picture they'd sent. They never had the transmission, they just found one they thought they could buy and resell to me and then when they didn't win the auction for it, they ghosted me. I emailed back with that information, and they said they'd have to charge a restocking fee to refund my money. A restocking fee... for something they never had. 🤬🤬🤬 It took 3 more emails to finally get a full refund.
