I have a problem with my 36 ford transmission jumping out of gear under acceleration and deceleration. I also have another tranny which I was going to install but want to find out how to check it before I install it to make sure it doesn't have the same problem. What is the main cause of them jumping out of gear? Help dneddinger@sbcglobal.net

Would a transmission shop have the ability to check a transmission like this without it being in the car? Just wondering. I can understand you wanting to find this out first, before the trouble of installation.

They would if you found the right one but most of the shops haven't even seen a 1935 tranny. They are very simple but I just do not know the tolerances.

Yes, but it will require some disassembly. There are a few things that would be responsible for popping out of gear. Adjustment of forks, worn forks, damaged roll pins in shifting rods to forks, worn thrust washers, worn or mis-adjusted linkage.

Even a transmission that slips out of high gear after all probable causes checked out and all OK and has the mechanic scratching his head sometimes can be found in the transmission alignment of the crankshaft pilot or the clutch housing bore (that happened to me early on in my automotive career and I was the guy scratching my head) All things must be considered.

Everything that helfen above said but also on early Ford transmissions that jump out of gear can sometimes be cured by removing the gear shift housing, pulling the shift rods out of it and stretching the detent springs a little.

This will put more pressure on the detent balls and stop it jumping out of gear. Check the detent balls for wear also as they may need replacing.

You could also contact Van Pelt sales who publish a book called "The Ins and Outs of Early Ford Transmissions." This is probably the best book ever written on the V8 transmissions.
