Greetings guys.
Wasn't sure whether to post here or in the Diesel Engine Discussion in the Garage. Figured it may get more of a response here . . .
Anyway, I've got a '91 Terrano with the TD27T diesel power plant. Auto transmission kinda died on me the other day, running at 230F, fluid black and burned, no 4th gear, and misting out of the filler/dipstick pipe. And no, it wasn't over filled! So it looks like time for a new transmission, or attempting a rebuild
Now, I've got an auto transmission from a 1994 VG30E Pathfinder that I'm breaking for parts. Will need a rebuild as it sometimes didn't like to find 3rd when the truck was running, but that would be a fun project.
So my big question is, can I install the auto transmission from the 1994 V6 Pathfinder on the 1991 diesel Terrano?
Both units are the RE4R01A transmissions, but whereas the '94 Pathfinder tranny is the 45X72 model (a 1991 V6 Pathy tranny is the 45X24), the transmission on the Terrano is the RE4R01A 45X15. I've done some extensive part number comparisons, and while they're very very similar, there are some internal differneces, in particular in the valve assemblies and the drive and driven plates. Of course the bell housing is different, but they're easy to swap over. The oil pumps and input and output shafts are the same though.
Could I install a rebuilt 1994 V6 auto transmission, re-using the diesel bell housing and using a diesel torque converter, on my diesel engined 1991 Terrano? By the way, the '94 uses an electric speed sensor while the '91 is mechanical. Would I need to use the auto transmission computer from the Pathfinder or the existing one in the Terrano? Any help would be greatly appreciated!
Reason I'd rather rebuild the Pathfinder transmission is that I have all the data (tolerances, clearances, thicknesses, end plays etc) from the FSM. What I don't have are the factory service manual S.D.S. tables for the TD27T diesel unit as auto box diesel Terranos were only every sold in Japan. Diesel Terranos on the European market were manual as far as I can work out. Of course, if someone can supply me with the data for the diesel unit, I could rebuild that one and not worry about compatability issues. Anyone got the data and willing to share?
