Used Transmission Information
A used transmission is just that, a used transmission. They are just guaranteed to be a used Datsun Roadster transmission, with no broken gear teeth, nothing more. We consider them cores to rebuild, repair or use as is. If you want a completely good transmission, rebuild one or repair one.

If I was to go through any 5 speed and put my name on it the cost would probably end up about 4-5 times whatever prices are listed here. If I was just to tear one completely down to note even any visible problems it could raise the price by 50% just because there are so many things pulling at me to do them these days. And that would assume I could ever accumulate that much fun-time i.e.sitting on a stool at my workbench arguing with some snap rings. I miss that a lot. I remember one time when I had about 8-9 boxes all laid out and did them like an assembly line. When they were all done I could have done another in my sleep.

WHAT WE DO: 1500/1600
Oil pan is pulled off and a visual check is made for broken gear teeth, broken forks or something else obviously wrong. It is NORMAL for the reverse idler gear to look a bit beat up. Transmission is shifted into each gear and hand turned to check response. This is only a simple inspection and check, MANY things can not be apparent (bad bearing etc). Countergear is wiggled to check for gross internal bearing wear. Synchro's may or may not function properly, there's no way to check them accurately without the transmission being checked in an operable car. Sometimes we can tell if a one or more synchros are COMPLETELY gone, but NOT ALWAYS. Transmissions with obvious problems are set aside or sold with a specific part number with their own specific description, but if you want a trans with nice synchros, put new synchros in! Oil pan is put back on, with the OLD gasket, or remains thereof. You should ALWAYS order a gasket and seal kit if you don't already have one.

WHAT YOU SHOULD DO: 1500/1600
The biggest problem with these is the bearings and shaft inside the countergear gets worn then the counter gear can move away from the mainshaft. At certain times only the tips of the gear teeth are engaging, which leads to them shearing away. ($$$$). ALWAYS yank the front cover and rear tailshaft housing before intalling a transmission (or when you do a clutch job) and check the shaft and bearings. Unless the shaft is MINT (no visual change to surface) replace it and the bearings. ALWAYS replace the countershaft bearings. Servo boxes use caged needle bearings, Warner boxes use individual needles. On the Servo boxes there are bearing spacers inside each end of the counter gear. Don't lose them as they are getting impossible to find. Normally your old ones will be useable. Be sure to order the appropriate gasket and seal kit.

OPTION 1:
Cases are pulled off and a visual check is made for broken gear teeth, broken forks or something else obviously wrong. It is NORMAL for the reverse idler gear to look a bit beat up. Transmission is shifted into each gear and hand turned to check response. This only a simple inspection and check, MANY things can not be apparent (a bad bearing etc). Synchro's may or may not function properly, there's no way to check them accurately without the trans being checked in an operable car. Sometimes we can tell if a one or more synchros are obviously gone, but NOT ALWAYS. Transmissions with obvious problems are set aside or sold with a specific part number with their own specific description. Cases are loosely put back on, with the OLD gaskets, or remains thereof. You should ALWAYS order a gasket and seal kit if you don't already have one.

OPTION 2:
Rear tail housing is removed to check for VISIBLE 5th gear problems. It STILL can be slipping in use and feel OK with hand test; this look just determines if it is OBVIOUSLY in sad state do to loosening etc. Tail housing is just loosely reinstalled, with the OLD gaskets, or remains thereof. You should ALWAYS order a gasket and seal kit if you don't already have one.

OPTION 3:

WHAT YOU SHOULD DO: 2000
Always replace the rearmost countershaft bearing with the latest production version of the bearing (#323-02, on 2000 TRANS page hit link for BEARINGS AND BUSHINGS). Be sure to order the appropriate gasket and seal kit as well.
