Possibly.  But my boss called up the transmission shop we use at work and they told him they work on old transmissions too they are currently rebuilding a old Packard transmission.  Said for him to tell me that if my transmission doesn't need any hard parts like bands or pumps a simple rebuild would be about $800.

Im going to give them a ring as I might go this route.

Part of that $2500 overhaul job is the shipping costs to and from Jasper.

Don't try to over think the inconsistency of the transmission.  During an overhaul, all most likely hardened seals will be replaced, and the control valves will be cleaned and made to move freely.  Sticky valves and hardened seals are just a couple of things that could cause your problem.  There may even bee more than one cause.

I have the 56-57 Ford tranny manual.  In print plus a scanned version.  It has a great trouble shooting guide.  There is also a specific procedure for the linkage adjustment.

You might get a Shop Manual for that Year Fordomatic. Step by Step Instructions on overhauling them. They are very simple compared  to what they are using now.

  

Thanks for the reply.

What is confusing to me is how it only does this when I come to a stop while driving.

If I start the car now and put it in drive it will whine for about 5 seconds and go into gear and stay in gear.

Driving how ever coming to a stop it just went into neutral basically and whined and stayed whining while sitting still like it was low on fluid.

I just wish I could figure out what I could do to make it useable so I wont ruin a rebuilt Holley 4000 or another battery with having the car sit.

I contacted a few local transmission shops one replied back that a rebuild would be $2,500 for this transmission with me pulling the transmission out myself.  But said it would be a 7 to 8 week turn around as they have to ship it to Jasper for rebuilding.

I emailed Jasper just now to see how much they charge for rebuilding as I honestly believe $2,500 is too much money for a rebuild on this transmission when a rebuild kit is only $150.  I figured the transmission rebuild would be around $1,000 maybe $1,200 but surely not over $1,500.  I can buy a new rebuilt C6 transmission for my 82 F150 truck for $2,500.

I have one other last shot I will be calling a local shop by the name of Timeless Texas Classics they are off US 71 not far from where I will be moving to.  Going to call him up and see if he can do the transmission for me or if he can recommend someone.  Also want to get a price from him if he does rebuilds himself.

I just will do like Charlie from Charlies Transmissions has recommended to me by making sure they use more modern paper style clutches in the rebuild so I can run Dextron transmission fluid.

If I remember to I will try to get a video tonight or tomorrow showing how it goes into gear and stays in gear in D when sitting still to show what its doing that is causing me to be totally confused on how it can slip out of gear in D in one situation and not the other.  Causing me lots of headaches for sure.

I read all the posts on Fordbarn about your question.  There are several good replies, but no one mentioned the operation of the hydraulic system.  When you are in drive and come to a stop, the transmission is trying to go into 2nd (remember it normally takes off in 2nd), which means the front clutch and front band should apply.  If either one doesn't apply, the transmission freewheels.  When you manually shift it to low, it uses the front clutch and REAR band.  Since it now goes into a gear, then the front clutch probably stays applied in both modes.  Therefore, the front band is most likely not applying.  Those on Fordbarn that suggested an overhaul are on the right track, especially with 155, 000 miles.  The whine you hear is probably the fluid pressure control valve in the valve body.  My old mind seems to recall a Ford service bulletin from back in the day that addresses it, but I could be wrong.

Took the car out first time self propelled since the early 80`s.

Thing I noticed is transmission shifts great doesn't feel like its slipping but when I come to a stop the transmission falls out of gear and whines in neutral like its low on fluid.

I already when I put the Holley 4000 back on I adjusted the bell crank and transmission rod to the book.  I have it currently set 3 turns counter clockwise from internal stop of the transmission which it states do not go more than 3 turns.

This to me feels like a line pressure issue and I am wondering would it hurt the transmission or driveability if I do some trial and error and go half turn to one turn at a time to increase line pressure to keep it in gear when I come to a stop?

What makes it real odd to me is it whines going into gear and I can force it into gear by going into low but if I shift to drive it will stay in gear as long as I want.  this dropping out of gear only happens when I am slowing down coming to a stop.

Aside from that down shifts great and shifts properly.  just need to figure out the stumble off idle where the carb wont take fuel but that isn't related to this transmission problem.  Want to address this issue first.
