Selling my spare CT15 turbo. Check out my post on Ebay.

yeah a good fabricator can fix those broken brackets, if you have the pieces. good luck!

That's repairable with some aluminum braze, if you really wanted to.

The gearboxes are identical aside from the gear ratios inside.

Also, take a look at the speedo sensor - it may have been cable driven still in 93, so you would have to swap the electronic one from your old gear box. They can be a royal PITA to get out if things are rusty, so be careful. I've broken one or two taking them out back when I was yonder and un-wiser.

It'll still accelerate slower because the final drive on the S51 is also longer. But, if the car we're talking about is the one with 3SGTE, then S51 is the better gearbox - the engine has more power (and higher redline, too, iirc), so you want the longer gears/final drive.

And yes, that's the electronic speed sensor - the 3 pin plug right above the pas side axle.

Back when I was still abusing my Camry, I actually made a hybrid gearbox with the shorter S54 1-5 gears and the longer 5th gear and final drive out of S51. It worked out pretty well - I had noticeably better acceleration in 1-4, and then the longer 5th gear for acceptable highway revs. The 5th gear synchro was not happy though as the differences in rpm b/w 4th and 5th gear was higher now. Had to shift slower into 5th or it would grind.

Keep in mind that the Camry box has different (taller) gears and final drive. The car will accelerate a tad slower, and your highway RPM will be lower.

If you're committed to replacing the gearbox, I may be interested in your old one with the LSD. If the price is right, I'll take a chance at repairing it. Let me know...

It is but they're all parts inside, as long as the case halves aren't boned you can split it and fix it usually.

Sigh, that blows. If it's just the carrier though why a whole other transmission and not just get a new carrier?

Can you quantify "serious in and out play"? Also, I'm assuming we're talking driver's side axle since you mentioned the snap ring which is not present in the pas side axle.

Some in and out play is normal as there's some slop in the snap ring securing mechanism. Maybe about 1/8 of an inch.

With aftermarket axles, you MUST install a new seal with a new axle. OEM seal is much preferred - I've had aftermarket seals leak within weeks of installation. As you may have heard, quality control on aftermarket garbage is non-existent, and sometimes the shaft is slightly undersized. A new seal will wear to the shaft, if you will, and seal. If you then take a new, random-sized shaft, and the old seal that was previously working on a different sized shaft, you get a pretty massive oil leak - you'd be surprised just how much oil can leak past. We're talking puddles, not just stains under the car. Ask me how I know.

The fact that a third axle would not even snap in does not surprise me either. I've had aftermarket axles where the snap ring it would seem was bent out of some standard wire not treated in any way with no spring to it, and that garbage will deform and not go in when you try to insert it. I've had to remove original springy snap rings and put them onto brand new aftermarket axles.

TL;DR: Aftermarket garbage is the root of all evil and belongs in the garbage.

I want to say the manual and auto use a different axle and that the length of the part that inserts into the trans is the difference, with one being longer or shorter than the other. I'm assuming it's the driver side because they're the same auto or manual on the right side it seems.

What often happens is that cores aren't sorted/boxed right when they go back for refurb so you'll get parts randomly boxed wrong that way. Might be worth checking inside the diff with a flashlight to make sure nothing has gone wrong, how did the old axle that came out look? Is there excessive up down play in the bushing the axle rides on?

^That. My brother had issues with his Maxima and more recently his Audi with CV axles and seals. Honestly I'd find a good used o.e. axle and refurbish it if possible, and use a new o.e. seal. That or use this as an excuse for custom higher strength axles.
