TCI Transmission is bad
Whew, i just finished reading all these posts. I rebuilt my first 904 in 1980. I had never done a trans before so I was lucky it worked. I had no idea what anything was (pre-internet), but a friend bought the parts and asked me to give it a shot. I figured wth. So, I don't know how many Torkflites I've done since then, everything from slant 904 to bb 727 , shift kits, bolt in sprags...lotsa bench jobs. One thing I do that I've never heard of any other rebuilder doing is packing the pump gears with grease so the the center gear stays centered and assemble the pump over a converter so it's ready to slide in the converter. Otherwise that center gear will flop around and the converter will never go in. This business of "clicking and clunking" the converter is rubbish. Measure how far back it is from the front of the bell and how far back the flex is from the block. Figure 1/8" clearance. Those pics of the back of the pump ate out looks to me like the converter wasn't all the way in the pump engaged correctly. That pushes the center gear into the back of the pump or breaks out the tangs. I don't get how some places figure they can assemble a trans and not air check it along the way. And these prices are flooring me. I do stock rebuilds for three hundred fifty dollars here in Hemet, Ca. And that even inckudes parts. I guess I'm gonna hafta raise my price. I just did a small block 727 and even furnished a core for six fifty; with a bolt in sprag and rv type Transgo shift kit. Never again on that one. That business of shipping transmissions for hundreds and even thousands of miles is for the birds. You hit a glitch and you're on your own. I stand behind mine forever. If dude messes it up it'll cost him, but I want it fixed; problems solved. Rebuild a trans in 45 mins? Gimme a break. Sounds like a leaker to me. It takes hours just to replace all those seals inside and out. Sorry, couldn't help it. I read posts on here where it was the builder's fault, but I also read many posts where I suspected the installation was sloppy. People think they can just jam it up in there like a stickshift. Pump gets toasted and they wanna start doing pressure checks...Jeeze. I love 727's; easy to work on and reliable like nothing out there, but you gotta know a few automatic transmission basics or it''s all turn to scrap metal in a heartbeat. I know of a few guys who rebuild their own and they worked, but there are so many details that if you overlook even one, it won't work. Not like a motor; it'll run unless it's really messed up, but a trans is unforgiving as all get out. The worst thing on a 727 is direct drum wobble. Ya gotta snug up that end play and replace that bushing...but it's still gonna wobble some. I know specs call for .040 endplay, but that's too loose for me. Here in the desert a trans can sit in the hot sun and gain .020. Those cases swell with the heat quite a bit. A big problem with diagnosing is that several different things can cause the same symptoms. I read all the complaints on this thread, and my heart goes out to some, but it's a headbanger when you don't even know if it was assembled correctly. I only actually read one complaint that I would take a stab at with a fair amount of certainty. Most sound like it's time to take everything apart and start checking every little thing; like what should've been done from the gitgo. Transmissions are sorta tuff to just dabble in once in a while. I say either dive in with both feet or let somebody else do it. Less headache, really. Didn't mean to write a novel.
