The jeep will be a around town rig for a bit....i dont have to take it on the Highway.......it wont hit the trails for a bit....So untill i can Re-Gear my self to 4.88'S will the jeep be usable? will it kill my trans? Im not looking to be a speed racer but want the jeep to pull its weight up a hill in lower gears......Has anyone Re-geared them selfs? how hard is it? Id like input from those who have done it....!!Thanks!

I believe the jeep to have 3.55 gears..its a 98 4.0 AW4

P.s will a hack and tap and a Auto XJ front D/S work with the 35's?

BTW, maybe go with 5.13's? I run 35 and its my DD.


Oh my bad your probably running stock axles.


Oh and a hack and tap serves the same purpose as an SYE, just less tech!

Yes....I have the D30 (?) in the front.....and a Chryco 8.25 in the Rear...However i have a D44 from a 87 XJ That will be Re-Geared......
 
it'll be increasingly sluglike, get poor gas mileage and you probably won't be able to pull OD much except on flat ground in a tail wind. But it won't hurt anything

except the tranny. if he overheats it. which is rather easy with stock gears and 35's. avoid long trips and lots of hills. wheel in low range as much as possible
 
Just be easy on it. I run 35s on 3.50 gears without a problem, but I have a manual trans, so overheating it is not so much of an issue.

No but not using OD will keep the trans in gears where the engine makes enough power for the torque converter clutch to stay locked up thus lowering trans temps. The OP already said he's not gonna be wheelin.

It's just like with the old 700r4 in GM trrucks where you weren't supposed to tow on OD because the TCC would say unlocked continuously because of the strain and the trans would overheat as a result. But your premise that just because the final drive ratio is high that the trans will fry is just false. Ive owed cars with much higher final drive ratio's than the OP mentions.

2.29gears on even 26" tires is pretty darn high

Yeah stock gears with 35's are gonna be ruff, especially on the tranny like stated above. Heat will kill the tranny. I have 4.88's with my 35's and I'm still worried about my tranny temp.

I wouldn't recommend
 
I'm in a similar situation with 31's on stock gears. It was suggested to use 3 instead of OD to gain better acceleration. Obviously that is a temporary solution- gearing is a better fix. Depending on your axles, it may be wise to swap to a Ford 8.8 with disc brakes in the rear. I'm pretty sure many of them come with 4.10 gearing. Although that isn't a straight swap, there are some adapter kits available and it is a common upgrade. For the front, you would do a matching ratio and the stock axle may be fine for you.

I looked through someone's photo write-up and it is pretty labor intensive. You also have to make sure the new gears are meshing properly, etc. Not trying to scare you away from it, but it looks like a pretty big job to me.

Running a tire larger than stock effectively makes 1st, 2nd, and 3rd TALLER gears aka more load is placed on the transmission. In an auto, the TC will slip more and create more heat in ANY gear. In a manual transmission, you have to slip the clutch more to get the rig moving effectively wearing out your clutch faster.

Sure not using OD will help on the highway, but not so much for getting moving.

So manually shift the jeep?

no. a manual transmission doesnt over heat the way that automatics do. manually shifting an auto matic is not going to help
 
Well i meant to say keep it out of OD......right? but doesnt the TC lock up on the highway so it wouldnt be creating alot of heat?
 
i drove around for 1 day in my 93 with 3.55 gears and 35's and it was horific, atleast the 33's that were on it were liveable

do you guys even know what a TCC is and what it does????? Do you think an AW4 is that big a POS that it can't handle the really not that high ratio the op ends up with in daily driving?

Sure 35's and 3.55's may seem high to the jeep community but in the grand scheme of things automotive it really isn't. I drove a 403 powered cutlass for years on 27" tires ans 2.29 gears and the tranny didn't melt and run out from underneath the car in a puddle and that was in the days before lockup torque converters


Will 35's on 3.55's suck YES

will it be instant death to his trans just because NO (unless the op drives like a total dweeb)
