Gophman Posted April 25, 2019 Report Share Posted April 25, 2019 My '47 Windsor won't automatically upshift, I originally thought it might be electrical but I have checked the system and all seems well..... If I remove the interrupter and build the revs up in 3rd I can see the piston slide forward in readiness for a shift but it never actually shifts into top so I suspect the hydraulic side is ok also. I suspect that for some reason the shift slide (or whatever it's called) just isn't engaging. Are there any walkthroughs on inspection of this or will I just have to use the manuals?

keithb7 Posted April 25, 2019 Report Share Posted April 25, 2019 Have a read here. Also suggest you search youtube for the slide show that Chrysler produced. Its on there and quite good. http://www.imperialclub.com/Repair/Lit/Master/012B/index.htm Quote Link to comment Share on other sites More sharing options...

Tom Skinner Posted April 25, 2019 Report Share Posted April 25, 2019 Is your 10WT Non-Detergent Oil full in the Tranny? Is your Tranny Screen Clean? Have you checked all your Electrical Wires and Connections? Also is the Fuse in your Tranny Selenoid good? Just a small check list before a full on trouble shoot from the manual Tom Quote Link to comment Share on other sites More sharing options...

Gophman Posted April 27, 2019 Author Report Share Posted April 27, 2019 All electrics work as they should, ditto hydraulic system. I pulled the trans today and found a synchro ring out of position (two tangs not lined up with recesses) corrected and refitted and all working now! Two and a half hours we'll spent. 1 Quote Link to comment Share on other sites More sharing options...
greg g Posted April 27, 2019 Report Share Posted April 27, 2019 Glad you got it figured out. Only 2.5 hours you must be much more skilled than me. Quote Link to comment Share on other sites More sharing options...

keithb7 Posted April 29, 2019 Report Share Posted April 29, 2019 (edited) Just to clarify. You dropped the tranny? I assume removed the shift linkage and cover on the side. Found the issue by viewing through window that was created when the shift linkage was removed? Am right to assume the rear section of the tranny was not removed? Thx.

Gophman Posted May 1, 2019 Author Report Share Posted May 1, 2019 No I removed the tranny, stripped the oil pump/rear of the case to allow removal of the cluster and found a sycro not located properly and rebuilt/refitted. Quote Link to comment Share on other sites More sharing options...
Dodgeb4ya Posted May 1, 2019 Report Share Posted May 1, 2019 Odd that a direct speed blocker ring could change position.... the two tangs that fit into third speed gear should never be able to do that unless worn...if that was the issue. 1 Quote Link to comment Share on other sites More sharing options...
Gophman Posted May 1, 2019 Author Report Share Posted May 1, 2019 Tbh I had the cluster out previously to replace the reverse gears, the blocker stayed in the trans an I didn't notice that it hadn't lined up correctly when I refitted the cluster and the car hadn't been driven on the road since. 2 Quote Link to comment Share on other sites More sharing options...
MarcDeSoto Posted May 2, 2019 Report Share Posted May 2, 2019 Oddly, I sent my MTSC filmstrips into the Imperial club when I saw they were missing them for the 1946-48 M-5 transmission, but the filmstrip is no longer on their site. but it is on the Youtube site. There are two shows, one on How it works Special Kit A, and the other on How to diagnose trouble in Special Kit A1: 1 1 Quote Link to comment Share on other sites More sharing options...
