May 14, 2006I was wondering if my transmission is safe running my 285/75/R16s on my stock 3.73 gears on my 01 Z. Another question off the topic...I have a K&N cold air intake. I just noticed this morning when checking oil&tranny fluids that my mass air flow sensor was not plugged up. Would that hurt my performance with it like that? I plugged it back up and yes the engine was running and when I did plug it back in it sounded like the motor got a slight boost of power. Any feedback is appreciated.
May 14, 2006Tranny's fine with those gears/tires.
If the engine was running lean without the MAS, it could cause damage. You probably would have noticed abnormally high engine temps if that was going on. Most likely you're fine.
May 14, 2006tire size and gears should be fine,
it's a wonder it was even running with the airflow sensor unhooked
May 14, 2006Your tranny will be fine with 285's. What do you mean not plugged up? I assume you mean not plugged in; I"m really surprised it idled right unpluged. On my last truck I forgot to plug it back in after I pulled the screen out of the MAS and it wouldn't idle. Then it dawned on me that I forgot to plug it back in. You need it pluged in cause it measures the amount of air going in the motor, among a few other parameters, so the motor can adjust the fuel accordingly. Without it your running blind if running at all.
May 14, 2006Does removing the screen from the MAF sensor actually help air flow and performance without any adverse affects?....
May 14, 2006your tranny will be fine i am running 35in. tires with my stock 3.42 gears and im doing fine i just have a extreme loss of power. I am only doing this cuz i dont have the money for the new gears yet im saving for em. I should have 4.10 or 4.56. your tranny will have no prolbem with those tires at all.

You're not "doing fine". Your tranny temps are running high and you are shortening it's life quickly.
May 14, 2006usually with the MAF unpluged your truck will barely idle at about 300-400 rpm and you will feel it alot.
May 14, 2006my buddys got 3.42s an 35s been like that for 156,000 miles an no problems, i ran 35s with 3.08s for a long time with no problems, but the 4.56 are alot better
May 15, 2006Manual or automatic though. The big problem with being undergeared is with autos.
