stheodore10 Posted April 29, 2014 Report Share Posted April 29, 2014 Hey all, First off so I don't sound like a noob from here on out, if someone could tell me the name of the transmission that I have that'd be wonderful ^^ So onto the problem. When I picked up the car the trans seemed fine, hitter was in neutral, car rolled. Everything was hunky dory. So when I put it on the trailer I put it in reverse for added safety. Now the shifter moves through the gears properly but it's still in reverse. Can I please have some suggestions?! Thank you all Quote Link to comment
datzenmike Posted April 29, 2014 Report Share Posted April 29, 2014 F4W63.... '72-'73 620 trucks have them but not after '73. The 510 wagon has the same ratios, while the sedan has slightly closer ratios but will work. The 710 and A10 car 4 speeds will also work. The 610 won't fit for length. If you find a 521 4 speed it can be made to work. '74 and up longer 71B 4 and 5 speeds will work if you also get the trans crossmember and the front half of the two piece driveshaft. Look under the shift boot at the linkage. Has the pin fallen out of the striking rod. Move through the gears. Quote Link to comment
stheodore10 Posted April 30, 2014 Author Report Share Posted April 30, 2014 havent gotten a chance to look for it yet but in the meantime ive decided it would be a good idea to brush up on my transmission removal skills... would you happen to have a link handy? Quote Link to comment
datzenmike Posted April 30, 2014 Report Share Posted April 30, 2014 Drain transmission Remove starter, mark driveshaft so it can be put back in the same position on the differential and remove, remove shift lever and clutch slave and disconnect the transmission switches and tie out of way. Speedometer cable is on driver's side and just needs loosening and unscrewing... tie out of way. Unbolt rear transmission mount and cross member and allow it to droop slightly with the engine, supported by a hydraulic jack under the oil pan. Reach up and remove the transmission to engine mounting bolts. Be sure all bolts and screws are removed between transmission and engine. Shake transmission up and down, side to side by grabbing the rear tail, and transmission should separate and move back. Have a care as it is heavy and can suddenly fall out... have some support ready for this. Quote Link to comment
stheodore10 Posted May 6, 2014 Author Report Share Posted May 6, 2014 moves through gears. heres what ive found: Quote Link to comment
stheodore10 Posted May 9, 2014 Author Report Share Posted May 9, 2014 so basically its in reverse unless the clutch is in or i move into another gear... this cant be normal can it? Quote Link to comment
ggzilla Posted May 9, 2014 Report Share Posted May 9, 2014 Yes, that's normal if the pin is out. You can view the pin from inside the car. Quote Link to comment
stheodore10 Posted May 9, 2014 Author Report Share Posted May 9, 2014 I'm not exactly sure what pin you're talking about... Not the selector rod right? Quote Link to comment
datzenmike Posted May 9, 2014 Report Share Posted May 9, 2014 More or less normal operation. There is enough thick oil being pushed around by the counter shaft to move the mainshaft when idling in neutral. Sort of like a torque converter in an automatic. If the wheels were on the ground it wouldn't spin in neutral. The striking pin down at the bottom has been replaced with an ordinary nut and bolt. This won't cause a problem but the shifter will be loose/sloppy unless a washer is also slipped in there. It has to be snug but not over tight as the pin and rod must be free to rotate.

stheodore10 Posted May 10, 2014 Author Report Share Posted May 10, 2014 So just hooked up the rear half of the driveline and tried it : Clutch in: fine Clutch out in neutral: backed up until the tires hit the curb Clutch out in reverse: same as last Clutch out in first: truck dies So confused Quote Link to comment
datzenmike Posted May 11, 2014 Report Share Posted May 11, 2014 Your video clearly shows the driveshaft turning reverse while in reverse. It also shows neutral spinning the other direction and 4th spinning even faster so what it shows and what you say, do not agree. Quote Link to comment
stheodore10 Posted May 11, 2014 Author Report Share Posted May 11, 2014 ok so now im really confused, i could take a video of it but when i started the car, shifter in neutral clutch out, the car moved backwards until it hit the curb Quote Link to comment
ggzilla Posted May 11, 2014 Report Share Posted May 11, 2014 Pull the hand brake on before starting the engine. That'll solve the crashing. 1 Quote Link to comment
datzenmike Posted May 11, 2014 Report Share Posted May 11, 2014 Weird, the driveshaft appears to be turning two different directions to me... and forth gear spun faster. Quote Link to comment
stheodore10 Posted May 11, 2014 Author Report Share Posted May 11, 2014 handbrake needs some work :wacko: so what does this mean for me? is there something i can do? should i buy a new one? going to be around $300, or should i take this one to be repaired, maybe using my spare for parts?

ggzilla Posted May 11, 2014 Report Share Posted May 11, 2014 $50 is the going rate for 1973 transmission Quote Link to comment
stheodore10 Posted May 11, 2014 Author Report Share Posted May 11, 2014 i was also thinking about doing a 5 speed swap if im dropping the trans anyway, but if not where do i get one for $50......? Quote Link to comment
stheodore10 Posted May 16, 2014 Author Report Share Posted May 16, 2014 drained the trans, opened the pan and had a friend run through gears. with this video can someone better helpme? Quote Link to comment
datzenmike Posted May 16, 2014 Report Share Posted May 16, 2014 Only the 1st and 2nd gears are engaging (watch shift fork on left) even when shifting 3rd and 4th. The 3rd 4th fork seems to bump when selecting reverse. I would check the linkage at the shifter below the boot. They don't call the A type shifter the 'Monkey Motion' for nothing. The name is very well earned. My 521, you could grab the shifter while in any gear and move it in a circle the size of a basket ball. Talk about sloppy. Quote Link to comment
stheodore10 Posted May 16, 2014 Author Report Share Posted May 16, 2014 When you say linkage what exactly are you referring to? The nut and bolt that replaced the pin you mentioned earlier? Quote Link to comment
datzenmike Posted May 16, 2014 Report Share Posted May 16, 2014 Most likely there is way to much play or slop. Quote Link to comment
stheodore10 Posted May 17, 2014 Author Report Share Posted May 17, 2014 I still don't follow, if so is this something I can fix myself? And if not could I just drop the trans and bring that in for work or does my whole car need to be there? Quote Link to comment
datzenmike Posted May 18, 2014 Report Share Posted May 18, 2014 It's the area where the shift lever joins the horizontal striking rod that enters the transmission. The striking rod rotates when the shifter is moved from side to side but also moves out and in as the shifter is moved forward and back. Any excess slop in this connection and it won't shift properly. Quote Link to comment
ggzilla Posted May 18, 2014 Report Share Posted May 18, 2014 There is a replaceable bushing that goes right there. Quote Link to comment
stheodore10 Posted May 19, 2014 Author Report Share Posted May 19, 2014 Now I understand. Let me put a shim or two in there and get back to you Quote Link to comment
