Has anyone had WJ problems when installing oversized tire?
The Jeep dealer told me today that some people have tranny problems when installing oversized tires. I don't remember if my torque converter started acting up before or after the tire switch, I think it was after. The mechanic that updated my pcm and tcm told the service advisor that his Jeep acted up after he installed larger tires. So has anyone else had this problem, or do you all for chips?
I have a 2005 Jeep Wrangler with a 4.0 I6 and auto tranny. I havent had any trouble with the transmission until i changed the tire size. I went from the factory tires to **** cepek 17R35 Mudders. Now when the trans gets warm it doesnt want to shift down to 1st. No problem in reverse or higher gears. At times if i accelerate strongly it feels at if the trans slips out of gear and after my rpms and trans pressure lowers it starts to pull again. Dont know if this helps, but i havent narrowed the problem, if you have please let me know. Thanks.http://www.jeepforum.com/ubb/confused.gif
bought my 99 jeep wj 4.0 at 90k miles. already had larger tires on(the largest that would fit with stock suspension. minor rubbing) Rebuilt tranny at 130k because reverse went out (partially my fault). Leaky transfer case caused the fluid to get low and the gears to slip. did not know for about a week. About 2 weeks after i changed the seal, I gassed it in reverse while against a high curb. The shop who rebuilt the tranny installed an aftermarket tranny cooler. has worked good since. now at about 145k
