1991 4runner 4WD question
I just recently bought a 91 4Runner with the automatic A340H
transmission. I can't find a definitive answer on the web about this, so I thought I'd post here. Is the 4WD system on this vehicle shift-on-the-fly, or do I need to stop/slow down significantly first? I had a Wrangler, you could engage at up to 55mph for 4WD hi. Please respond with the allowable shift speeds for both 4WD hi and 4WD lo if you know them. |

If you have the Automatic Disconnecting Differential (ADD) front axle, http://www.off-road.com/toyota/tech/add/index.htm then I think 50MPH is the max. 2Hi<->4H shifting speed. Your Owner's Manual would have the exact specs. You might try asking on the Yotatech web forum: http://www.yotatech.com/forumdisplay.php?f=2 Lots of 2nd gen owners hang out there. -- Roger |
