15K or so on trans....clutches fried or just T/C?
I will try to keep it short, but please bear with me. I installed a PI engine and tuned it with my xcal, 2 weeks later stock trans was TOAST, OD shift took about 15 seconds and banged REAL hard. So I replaced the whole driveline and it seems SOMETHING is wrong with every piece of it now. Engine, trans, and diff, but I will post on those in the appropriate forum section.
This trans is the most depressing of it all. I am still paying back on what I have done so far, much less pay to get another trans/rebuild like I am thinking I will have to do eventually. I like things to work like they are supposed to, not half-%@^ like this.
I bought a mild Jmod trans from Darrin, and a marauder converter to go with it. When I installed it, I missed one of the harness connections. It would not shift at all. Darrin fabricated me up a manual shift box that manually controlled the solenoid, and this proved that the trans was indeed good, and it was the wiring. After plugging it back in, it shifted fine but when I got back and checked the trans fluid, it was a tad low so I put a quart in and checked again and it read good. Haven't had to add any more yet. (Yes, I checked fluid with engine running and after shifting manually through all gears)
Aside from a very harsh reverse engagement, all was fine until the 3rd day or so of finally driving it again. I heard some kind of clatter noise and pulled over, checked trans fluid - checked fine, so I chalked it up to me hearing things again (my dad thinks I'm crazy). Never heard this sound again.
I don't know exactly when it started, but around 8-10K miles I started to notice a bog like I had with the old transmission, it comes at mid speed/rpm, the bottom of third gear. Engine gets quiet, muffled, and it doesn't matter how much gas you give it, the engine struggles to keep going and it just flat out chugs. That is, untill you give it enough gas that it kicks down to 2nd, about 2/3 to 3/4 throttle and it picks right up no hesitation. About 2 weeks later, I realized I could just tap the brake, unlock the torque converter, and off I go no hesitation. I don't think it is relevant, but about 33% of the time I shift to Park, I can hear a loud "click" from the trans. This started about the same time the "bog" came about.
So today my brother was in the car, and instead of tapping the brake I just gave it more gas so he could feel/hear it. After about 2-3 seconds I started smelling something smoking, so I quickly tapped the brake and unlocked the TQ and the smell went away.
It really gets old having to tap the brake every time and I am scared to let anyone else drive it because they wouldn't understand. But its either that or I just floor it everytime, but 14mpg isn't a very practical solution. Even though I don't drive very much, the majority of my driving is in town where 30-35 mph 3rd gear situations are common. I might just start driving around town in manual 2nd!
So what gives? Anybody have any ideas about how I messed this up? I am hoping that it is just the T/C but have a feeling its something internal, but if it was internal would it not happen all the time? I mean this trans will chirp the tires on the 2-3 shift with heavy throttle. It shifts really hard even at low throttle and often times chirps on the 1-2 at slow speeds in turns, and I have a true-trac 3.73 diff. When the torque converter is unlocked, the acceleration is awesome, but when the torque converter locks, its a slug and it sickens me.
Any advice will be much appreciated...
All Glory to God!
