Help with 727 trans 2 problems

[Slappy]

Thanks to all that can help. I have two problems. First is a trans linkage issue. I have two A-body cars that used to be 6cyl. cars. The trans linkage pivot that bolts to the frame is my issue. No matter what I do the rod going across to trans is to long and will not sit level. It is preventing me from getting manual shift low one. Was the linkage different from a 904 to a 727? I dont know what was in it. Is there an aftermarket one? I have this same issue on my other car. If the pivots that mount to the frame are different between the transmissions, does someone have one?

Second issue is on the same car [75 Dodge Dart Sport] with the linkage issue I have installed a lockar throttle pressure cable. I cant seem to get it adjusted properly. I know I have to fix the linkage problem above but it will go into drive with no problem. If I mess with the throttle adjustment I get anything from slipping ,late and early shifts and no third. I am confused. I really want to fix both of my cars properly. Any help would be appreciated.

In summary The engine has been changed from a 6 to a 318. Trans is different and could have been originally a 904 and now has a 727. I have installed a stall convertor of 2600-2800. I dont know what a stall should feel like. I have never had one before. Also on occasion the trans will puke some fluid onto the floor after sitting for some time. It will be clean for a week and look again and there is a half a quart on the floor. The trans has been rebuilt by a trans shop and I can only assume it is right. I also shortened drive shaft to fit the 8 3/4 rear. Some times ther appears to be fluid drips around u-joint at back of trans. Sorry for the long post but the more info you have the better. I can provide any pics you need. Thank you. Tod

The only difference in linkage from 904 to 727 would be in length, if there was a difference at all. There may also be a difference i nthe linkage from the /6 linkage to the V8 linkage. No matter what, the linkage should have enough travel to engage all positions easily.

THrottle pressure should be adjusted to meet the following:

AT closed throttle, the lever on the trans should be all the way forward. At WOT, the lever on the trans should be all the way back. BOTH conditions MUST be met to have proper throttle valve operation.

For safety, the throttle should be able to close even if the trans linkage jambs, thu the slotted and sprung upper rod on the factory linkage.

Thanks for the advise. Tod

i got a cable from year one i believe (lokkar??) for my 6 cyl to BB swap, it works good once its set... i had to do some modding to get it to work right on the carb, and find a way for it hook up to the kick down lever without jamming on the tunnel. and had to hook up springs on the lever for it to return all the way on its own, on top of that it took quite a while to get the adjustment just right. i also found that if the cable is tightened all the way for the full lever movement at wot my motor is reving up to about 6000-6500 before it shifts so i had to set it back a bit constantly testing it until i found a place on the cable where my is now shifting around 4800 first to second and 4500 second to third, the kick down lever isn't pulled all the way back but its close i believe under half an inch or around a quarter its not much....
hope there's something valuable in that, you have probably already figured out the majority of it..
