Howdy, I just got a 'new' 03 v6/5spd Mustang a few days ago and noticed a couple things after driving it a little bit. My transmission(t45?) makes a whirring noise in all the gears at higher rpms, 3000 and higher. I can't hear it with the stereo on. It's not nearly as loud as the t5 I had in my other car, or the Tremec in my buddy's car. I was just curious how loud other people's are, or if I should go ahead and schedule a service time for it... Also, on an unrelated topic, I hit the rev limiter in first this morning and was curious if these ecu's pull timing or fuel when you redline. Also, do any aftermarket chips raise the redline on the engine? What's a safety margin? I noticed that it's set at a low 5300rpm and the gearbox seems too tight for such a low rpm....
Do you really want to risk cutting the limiter and blowing the engine on a mistake you could make? I bet everybody here at least once before screwed up on a shift and the rpms shot up to the redline scaring the crap out of you since it caught you by surprise lol. It happened to me a couple of times, specially missing 3rd when i had the stock shifter on. Anyways, doesn't the 03 have a T5 transmission? Or am I completly confused? and BTW, if this is your first mustang, get used to weird little noises coming from every which way, its a Mustang. If it is a "scray" noise though, doesn't hurt to check it out and see whats causing it, better spend a little now and not the sickening amounts to change the transmission once it falls out of the car
No, I've had an 82GT, 89 notchback and now this car. I was curious because manufacturers usually engineer a large margin of safety into what engines can take. If it's a T-5, I'm sure the noises are normal, lol. Overall, I'm impressed with this shifter's feel. It's much more sturdy than anything in my older 5.0's. The throws are short and kinda notchy, I pulled the boot down and it looks stock.
it really doesnt matter what a motor CAN take... there is NO NO NO NO NO point in going above 5500 rpms because you dont make any power there... thus you are just making your car slower by holding it.... and the stock rpm gauge is off so 5300 is probably more like 5500.... by removing the limiter you are doign a very STUPID thing, sorry but its true, i have seen idiots who do it and mess up their valve train or worse... and tehy expect ford to fix it lol well ford 99% of the time finds out its not their fault and its due to a alteration, last time i seen it the guy got sued by ford for trying to get them to fix his screw up. you can remove teh speed limiter with out touching the rpm limiter which is a better idea, the only reason to ever mess with it is if you actualy make power above 5500 or if you move it up a tad so that you can run an MSD box and cut spark instead of fuel if you run a blower or nitrous. the t-4, t-45 is noisy is it comming from the shifter tunnel ? you can put another layer of insulation around it and it may stop it from being noticable.
A few weeks ago there was a guy at the track with nitrous in a V6. He had written on the back windshield, I don't remember but something like ET 12.something or 13.something. Anyways, the light turns green and all you hear is a loud bang and the car doesn't move. The poor kid blew his engine.
