trini Posted September 26, 2015 Share Posted September 26, 2015 Can any one tell me when Dodge started manufacturing standard gear boxes with synchronise gears ? What is the possibilities of swapping a 1928 DB crash box with synchronise gear box . Just a thought. trini Link to comment Share on other sites More sharing options...
Guest Posted September 26, 2015 Share Posted September 26, 2015 (edited) It would be easier and probably cheaper to master driving with the original transmission. With practice you can shift up or down with an unsynchyronised transmission using the clutch normally, or double clutching or even without the clutch. Many trucks and busses were plain gears up into the 60's and 70's.There are some interesting you tube videos on truck shifting that you could watch.Seriously, a synchronized transmission would be more comfortable to drive but after 56 years and 400,000 plus miles I enjoy driving my unsynchronized transmission. However, If I were to start over again knowing what I know now, I just might convert my transmission.Happy hobbying Edited September 26, 2015 by Guest (see edit history) Link to comment Share on other sites More sharing options...
Marty Roth Posted September 26, 2015 Share Posted September 26, 2015 (edited) Agreed ! Shifting is a relatively basic technique, and when you are proficient you do not really NEED a clutch or synchronizers - just a convenience Just my opinion, and no disrespect intended, but shiftng even a brass-era car, even without using the clutch is a matter of matching RPM Edited September 26, 2015 by Marty Roth (see edit history) Link to comment Share on other sites More sharing options...
padgett Posted September 27, 2015 Share Posted September 27, 2015 Having mastered the art of getting into first gear at 25 mph with a Moss gearbox, I am very happy never to have to do that again. Link to comment Share on other sites More sharing options...
1912Staver Posted September 27, 2015 Share Posted September 27, 2015 (edited) Given the cost and scarcity of Moss parts I don't think I would risk a downshift into first while moving at all. Every time a gear grinds it does some damage, sooner or later terminal damage. There is a reason full syncro gearbox conversions are very popular for sports cars that get frequent use. I made my living repairing British cars in the late 70's to early 80's. Did many gearbox rebuilds , most are quite straightforward , except the shocking parts bills. These days many of the parts are either N.L.A. or offshore; questionable quality, sourced. Toyota or Nissan 5 speeds are a wallet saver in the long run, not so easy on a Morgan however, or was your Moss in a Jag ?

trimacar Posted September 27, 2015 Share Posted September 27, 2015 The other topic not discussed much about transmissions is the oil that's been put in them. Make sure you have the correct oil for your transmission.Too thin, and gears keep spinning. Too thick, and gears slow down. All this contributes to Marty's "matching gear speed" equation.

trini Posted September 27, 2015 Author Share Posted September 27, 2015 Thank you very much for the comments guys . I appreciate it. I am driving a 1995 5 speed manual Jeep Cherokee for the last 20 years and spoiled. trini Link to comment Share on other sites More sharing options...
Marty Roth Posted September 28, 2015 Share Posted September 28, 2015 Back in my SCCA days I got really good at replacing the 1st Gear / Reverse idler gear in my '58 TR-3 tranny -- and I wasn't doing it after every 2nd or 3rd race just for the fun of it !
