Rebuild 727 or Buy New.

[Briscoe Bum]

I’m working on a 71 Satellite Sebring Plus that I’ve owned for forty plus years. Now I’m getting ready to pull the tranny and have a shop go over it, new seals, and maybe a shift kit. I’d like to be able to beat on it a bit, I guess I always have and it held up fine, but i want to make this the last time I touch it. I’ve also been looking into the TCI or other strip/street transmissions you can get from Summit/Jeggs. Has anyone gone this route, how did they perform, and any other thought. Thanks in advance for the help, it will be greatly appreciated.

I've purchased the TCI rebuild kit and a new pump and had them rebuilt at a local shop I trust. Going on 4 years without issue. Make sure if you go this route you have confidence in the shop! 440'

I would find a shop or person who knows mopars and rebuild. Someone who knows 727 trans can do a lot with a trans by adding clutch packs and pumps for alot less than I could buy one. I have always been lucky to have a good mopar trans guy.

Thanks guys, I’ll probably go the route of rebuilding my old trans. I have a guy who know the 727’s inside and out and even gives a year guarantee on all parts and labor. I just like to ask around about few options before I pull the trigger.

You have a few options. Summit has a 727 rebuilt with HD clutches, deep pan with shift kit rated up to 600 HP for around 1600 bucks. If you can't find a "727 Wizard" then you could always go the AAMCO trans rebuild, comes with the warranty your looking for and honored across the nation. Good luck

Briscoe, you didn't give any specifics about the drivetrain. Mopar had many combinations of internal parts based on the engine power & torque. If you have a "warmed over" combo you want the correct 727 parts combo. The correct combination of OEM internals will easily support 500 HP or more. Rebuilding will likely be far less expensive.

Rebuild your self, they actually are really simple. There are a couple books that help. And YouTube vids. Only real special tool you need is to compress one of the clutch pistons. You use a feeler gauge to measure clutch gap, and and you measure endplay.

PTC convertors. Give them your specs, and what you want it to do. They'll build you one.

I've rebuilt my own with my own spec'd parts and haven't had issues. Pretty easy actually.

Or you can get one from A&A already ready to go for $1295+shipping. They are a top notch company.

If you want a higher shift point you might want to consider a Max wedge governor. Mines a column shift so I went with one. Should shift around 5800. Depending on what you have for a shift point. I think stockers are around 5500.

All you need is a well built stock 727 with a good valve body. A good cooler and deep pan will keep the fluid livable. This will easily live behind 700hp with no issue.

It’s a 383, bored .60 over, a mild cam, milled heads. It’s a “warmed over” and has plenty of power. As time goes on I wouldn’t mind doing some head work and such. I’d say I’d like a trans that would hold up to a 500-600 horse power. If anything I’d rather over build my tranny then have a failure. Thanks again guys for your answers.

Any good transmission shop can rebuild and upgrade the transmission. The problem is finding a "good" transmission shop.

Posting your trans id on the drivers side pan rail would be a great help on determining what needs to be done. Not all 727's were created equal.

I have a TCI Streetfighter. Since 2013, no problems.

Rebuilding a 727 is fairly straight forward, with a factory manual & some good advice. Seems today it's hard to find a "good" shop, especially for Mopars. A 'warmed" 383 will need the 4 disc front drum, red clutches, red front band, 3.8 lever(maybe 3.2 if that's what it has), 4 pinion front planetary. Valve body is a big choice. Aftermarket Cope, Turbo Action, ATI, etc is best. Stock with Transgo kit may be good.

Get the 727 handbook (carl munroe), study the areas that pertain to your type of build and don't be afraid to dig in. If your parts are cleaned, inspected, & methodical with reassembly, you'll be fine. You'll have a lot of satisfaction knowing you did it yourself. I've done over a dozen with no problems. If you need a few questions answered along the way there's plenty of helpful people on this forum.
