torqueflite 727, need help still...

Thanks for all the replies in the previous post. most suggestions tried to no avail. Looking for a recmendation for a mopar competent trans rebuilder in the atlanta, ga area, hoping that someone could refer me to one. If there is a friend out there, I've taken quite a bite in $ and time on this and someone willing to help a guy out with a great price would be very cool.

Also, any suggestion on simple reliable upgrades would be appreciated. Looking for snappy firm shifts at decent rpm point and unquestionable reliability. This is an 83 lockup 727 from a jeep grand wagoneer, had the 360 v8 up front.

Thanks so much in advance....again. Chris

Extra credit: For the'83 360 V8 there is 1 rectangular weight spotwelded on the flexplate on the tranny side. Does anyone know if the weight needs to be there on an 85 258 inline 6? For balancing purpose I assume, sure made aligning the converter bolts a hastle.

Thanks again!

Not sure if the 6 requires a balance weight Don't think so. IT would be different from the 360 weight anyway. I always used the B&M 360 LA flexplate with the balance built in - NO balance weight on the converter Trying to remember your last post? You had the Lokar throdle pressure cable. I hope you installed it correct IT comes in from the rear of the trans Not like the standard linkage from the engine side. Last 727/360 I had would leave about 50ft of rubber when shifted to second gear - street/strip shift kit

He did a driveway rebuild and now has a bad pattern with low TV pressure (high shift points and soft 1-2), had taken out a shuttle ball or two with a Fairbanks kit, and no word as to which bushing were replaced...reused old bands, etc.

It's going to have to be torn down and done right.

Have had big improvement in most areas, just still not right. Early shift on 1-2 that is soft and not that quick. Early shift on 2-3 that is very slow, with slip between leaving solid 2nd and finally getting to solid 3rd, 3-5 seconds shift (time). Though, if shifted at about

1950-2000 rpm it will shift pretty quickly and firmly, no more no less rpm. When cruising 3rd gear at 30-40 mph or so it seems as though a band is grabbing for a split second every now and then, like a very brief braking effect of the driveline that I feel. Still feels a little bit "bogged down" overall but much improved from earlier postings. From nuetral to reverse the shift is slow to take effect and not that firm when it engages, between the tcase and 4.56s the old shift to r was jarring to say the least, now pretty soft. While it all operates now, it just isnt all there. The valve body has been replaced, converter is new, tv valve cable installed correctly (still), the shift kit has been totally removed and back to stock configurations, Still have the 5:1 apply lever in, the 1-2 accumulator spring and the spring between the case and the valve body were taken back out trying to firm up shifts. Everything externally is correct, everything internally seems to be correct. This isnt my first rodeo, I'm very apt mechanic, built, destroyed and rebuilt crazy stuff. Just never automatic trannys, especially mopar. Rebuild a strait trans is no problem, makes me want my t-176 back. Just running out of time and anti frustration pills in this too long going process. Figure find a good shop and beg for a deal on a trans thats what I want. Still taking suggestions though, as its not getting better by itself before I get it correct. Man I would love to have a trans sthat shifts so quick and firm it almost hurts. Maybe grab up a little second gear on the 35's. Crawls effortlessly at 700 rpm idle, but can still manage to stop it on a steep downhill in 1L. Locks up firmly for maximum cruise speed of 65. And doesn't have a clutch pedal.

Thanks again for any help. Chris

So maybe y'all think ziz off the flexplate weight too huh?:) Was pretty much planning on it anyway.

Wanna come to atl for a couple days and make mine act like that? I got a fold out and beer. Just kidding, but must be nice!

That's low TV pressure. Are you SURE you hooked up that cable correctly? It comes from the REAR, NOT the front, with that setup, as someone else, I think Glenn, already stated. It could be you're working the TV valve backward, which would explain a lot.

Yes I'm sure its correct. I don't know how many times I've answered this question. However, as poor as the lokar instructions are I can see the possibility for confusion, but would it possible to mount it wrong? I would not know how or where to mount to make it come from the front.

But just to be real clear: With the motor off the tv accuator arm sits at about 2/3 way foward. With motor running (idle) the arm returns all the way foward with line pressure. With the carb at WOT the arm is just short of all the way back, I'm talkin about JUST short.

Thanks again guys.

Still no shop reccomendation?
