what diff gears for my automatic toy?????
« on: Dec 02, 2006, 08:04:07 PM »
I have an 85 with a 6 inch lift running 33's and auto trans.  It is a gutless slug.  I can hardly push my 33s and i want to put on 35s since the 33 look goofy with 6 inchs of lift, so what I want to now is whats the best gearin go option, It's my dailydriver/weekend wheeler.  I like the auto, but would like it more if I could get to 55mph in less than a mile, and be able to hold my speed on hills, without having redline each gear. Anyone have experience with autos and 4 cyl gearing help would be appreciated

               Thanks, Justin

My friend has a 85runner with the auto. He runs 5.29 gears with 33x12.50 swampers and he still seems to lack a little in the power dept. He can defnitely get up too speed just fine but doesnt always have the grunt to make the longer climbs.

You should be fine with 5.29's.  Need to watch tranny temp with 35's.  You might consider switching to a manual.

I have 4.88's in mine (granted, I have the 5spd), and with 33" tires it was great. Went to 35"'s, and I still loose a bit in the hills, and have to stomp on the noise maker a bit to get to full speed. With an juice box, I would certainly go with the 5.29's, as you'll need the extra gearing.

529 or 571.  http://www.gearinstalls.com/cosby571.htm

I had an 87 Runner 22RE with auto with 2 inch lift and 33x10.50 tires and I had US GEAR 571 gears in it. The thing I really liked about the skinny 33" tires is they had the 33" look but were much lighter and on-road acceleration was better. With a 12.50 wide 35" radial, I would imagine the weight will be felt more and 571 will look better and better.  With 33" tires, I was under 3400 rpm at 75 real mph on the highway.

oh ya....mine was not gutless :) ZUK

I ran 4.88's in my 86 4Runner with an auto trans, it was a little slow out of the hole but would fly when it hit 2,500 rpm I ran 33's and gave a guy with a v6 running the same setup and he said I had more power than he did, but maybe the fact that I was a turbo had something to do with that. :gap:



I'd go with 5.29's and an auto.

How are you A/T guys recalibrating the speedo??? Any issues with the shifts points on the A340 giving you fits since its computer controlled? I'm doing mine this week, and just need to know what is up and what options I have. If it doesn't effect the shift points, then I may just leave it alone.

My 22RE/auto/571 and 33x10.50 combo....I had a 10% error and never concerned myself with looking for a speedo fix....just did the 10% correction in my head. If I want to hold 60 on the highway then I look for 66 on the speedo. easy.
No issue with shift points....all was the same.

No issues with my computer and shift points being effected. I was pretty much dead on in the speedo dept. since I was running 33's and 488's.
