Decided to stop by, after all it's been I think almost a year since my last login. Life gets busy...
So on my SS I have a decision to make. Anyone who knows anything about the 4T65E-HD knows it is not the greatest transmission, especially when coupled to a tire-shredding LS4. Everyone I talk to says the life expectancy is 60-80k, MAYBE 100k. Well, I am just shy of 125k, so I must be doing something right. But I have always babied it (that's a huge understatement!).
PROBLEM: I have a "slip" developing. It is usually off the line, but twice I have caught it at ~50mph in O/D (4th). It is NEVER a slip between gears. Off the line the problem is gas->wait a 1/2 second->small thud->off we go. At ~50mph, the problem is under light throttle in 4th. When starting to go up a small hill and I start gradually applying more throttle it will also thud. Note, it never tries switching gears (as it shouldn't). Also worth noting, I do have a moderate trans fluid leak, not sure from where, but I don't think this will affect performace (I keep it topped off). I am not super knowledgeable in trans diagnosis, but I'm assuming this is a torque converter problem. I will go have it looked at before I do anything drastic.
HISTORY: I bought it with about ~75k on it. I purchased a handheld tuner to disable AFM (lifesaver!), but I also tuned all the shift points and pressures in the trans (also amazing). It IS the original trans. No work done in my possession. But I did drop the pan and change the filter at 99k (no issues, just routine maintenance). Used Dex VI. Old fluid looked clearly used, but very very good. No traces of darkness or smell.
QUESTION: What would you do? I am debating trying to fix it and selling it. I absolutely adore this car (except the trans) and bought it planning to go 300k+. If I sell it, I have equity, so I gain. If I keep it I figure a replacement trans is in order, and I figure a replacement is ~$2,500-3,000 (not doing this myself). Triple Edge Performance is my front-runner atm, as they are HIGHLY regarded amongst this transmission community. I just bought new tires too
. I am on a very small budget atm, which is why I'm asking opinions on this predicament. I know... go with your gut, and you know what's best for you, but I'm torn. I love the car, and would love to keep it. But I would gain financially by dumping it, when $$$ is thin. And I'm an incredible car shopper. But I'm addicted to V8s and 4 doors (no kids), and that market is scarce. Especially when you eliminate the 4T65E from the pool.
Sorry for the long read, but I REALLY value this community and it's input. But I also know that too much info is usually appreciated as well.
Thanks for taking the time, and hopefully you'll give your
. It is highly appreciated!
