First off I'd like to say Thanks to the Forums, I've gained alot of knowledge from here. I've got a 99' SR5 4X4 4Runner w/ automatic, when in 4 low, it will only shift up to 3rd or drive, it will not shift to overdrive limiting my speed to 48-50 if it's bouncing off the rev limiter. Is there anything I can do to the computer or manually make it shift?

One more question, is it possible for me to have the "special" 99 4Runner that is 1 inch higher than other 4Runners? I've got small fender trim, 4wd, factory 16's with factory bigger brakes up front. It was this way when I got it.

Thanks Terry S.

All the 4wd's I have owned have all been manual shift (untill the 4runner I have now) I've owned ford and nissan, both clearly states that when 4wd Low do not go past 3rd gear (on my nissan I think it said 30mph). I would say that it's a safety thing for the drivetrain in the autos. If you don't mind me asking why are trying to go 48-50 (or more) in 4wd Low. Put it in 4wd High. Now for me I havn't even ever run 50 in high. I use 4wd on snowy roads or i'm in some mud so even on the highway I never go faster then 30-40.

I'm not sure on the height of your runner. I'm kind of new to Toyota's so maybe someone else can help you there.

I don't think there's a special 99 Runner. As far as I know all 99 4x4s have the same size springs, which are indeed 1" taller than the 2000 and up.

And I don't think you'll be able to go faster than 50 in 4low, with the low range gearing of 2.2something that would be equivalent to about 110 in high range. And like Bigvick said why would you need or want to go faster than 50 in 4low.

1) No, that is as fast as any 4runner will go in 4WD low.....I won't ask why you aren't using 4WD high (hint: use that if you want to go highway speeds).

2) If you have a 99 4WD then you should already have the "special" 4runner that is 1 inch higher than other models.

Thanks for the replys. The reason I was using 4 low is bcause I was drag racing my runner at a local track and it is only 1/8 mile. I had a 2wd Tacoma reg. cab, stock and run fastest at 10.73 @ 60.** mph. The fastest I got my runner at is 11.83 @ 58.24 mph. The speed is there but it has squat out of the hole. With a passenger in there, my best was 12.06 @ 57.** mph, in 4low with a passenger I got 12.1 @ 45 mph. Low trap speed due to topping out at about 1/2 to 2/3rds track but it got there alot quicker. I cut .2 secs off 60 foot times and .5 secs off 330 ft times. I know, I know, I could break stuff doing what I'm doing but I'm a big boy and can handle the concequences (sp). I also know I have 4 high, pulled into 4 high at 70-80 mph with no problems. Also I have a 83' pu on 40's, before I lifted it up I could take 5th gear to about 60 mph.

About the ride height, I read in a post only certain 99's had the higher suspension. I was just wondering. I'm think about lifting it a little and was wondering how much I'd actually be getting. Also if I don't lift what would be the best route to level the back to the front with about 450 to 500 pounds of stereo in the back? I don't want air adjustable though. Thanks again

ummm... "oh".

Building torque in the bottom end by way of sacrificing your transfer case in the top end isn't a good idea. If you're gonna keep racing your truck with a stock engine, then swapping gears into the diffs is a better path to making this happen.

Past that, a supercharger and headers builds low-end torque, a turbo will get you let you build more HP up top...


If you keep running the truck like you are, you're gonna trash the low end gears in the transfer case. They're not meant to be run that fast, that hard, that consistently.

Thanks, ya I know its hard on it. I don't plan on alot of racing just once or twice before I put new sneakers on it. I have the stock wheels 16 " What are some good A/T tires that don't add alot of road noise. I have stock size also 265-70-16. One I was looking at was Dunlop Radial Rover RV. I had them on the 83 when I got it and I never got stuck and they were fairly quieton the road.

Would a elec locker rear end out of a 97 limited work in my 99 SR5? What all electronics would I need to rob out of the donor?

Also I just got 2 full front door panels with handles, all power switches and wood grain. Both kick panels, door seal plates, visors, driver rubber door seal, and 2-12 volt sockets for $150 bucks. I thought it was a good deal.

go with 265/75r16's
i personally like the nitto terra grapplers
dont lift it untill you are 100% ready to not drag race it. you dont want to roll it. and as far as a lift, i have the oem trd LC lift and like it. but if you dont plan hard wheeling, there are other cheaper solutions that get it lifted.
