Error 76 and 67

SOURCE: transmission error code P1750

Might be really simple - but EXPENSIVE! I had a similar fault - apparently the first planet set breaks up. Cure - a new box. Price - crippling!

Don't be tempted to skimp on the box. Get a rebuild from a reputable supplier. A s/h box will set you back around £5-600 in UK where a rebuilt (guaranteed) will be more like £1800. The thing with the cheap box is it costs about the same to fit but you don't know how good it is till it's too late! Then you're still shopping for another but you're £600 lighter!

Also, you could be buying other faults. If the speed sensor has had a problem - the box will change badly (snatching) and that will be another £250 where the expensive box will have ahad one fitted!

Depending on what connector is in this vehicle being that some 1995 where OBD2 and some OBD1 it would be better to take it to your local Autozone or Advanceauto they pull codes for free and can give you a print out.

SOURCE: 1995 Cadillac ETC has hard shift (all gears work)

yes change fluid. if that dosnt work buy new shift solinoids. and replace them. also check all the wiring from transmission to pcm and from conector to solinoids when u take the pan off. just disconect the solinoids. and use a digital multimeter innva brand put it on continuity and touch wire after wire till it beeps indicating wiring is touching . some will beep because thay are still conected and would have to remove transmission to disconect them. i just had this exact problem on my 94 sls . i replaced solinoid a-b and did a fluid change and checked the conections going to the transmission. and it runns good now
