Nope. I would call leading converter fokls and ask what they can do. I use Dynamic in Delaware.
Even though I am generally a cheapskate (due to having kids and cars to feed), I find that spending $$ in the right places doesn't hurt the bottom line as much as I would expect.
One just needs to have good judgment on what those places are and prioritize. Spending an extra $300 now won't be regretted.
Based on your initial inquiry on a TC, I got curious of that landscape. Saw some references that PTC was a good brand, and looked at Cope Racing Transmissions, which is somewhat near me and has a stellar reputation. https://www.coperacingtrans.com/?product=ptc-11-inch-torque-converter
Seems the 'smaller' 11" converter that the factory used for higher-stall applications isn't available anymore, you'd need a core to supply to Cope.
I also saw some mention that a smaller/tight converter would be more efficient than a looser/larger one.
I saw a video on his site last week, a Youtube clip, that he's no longer building transmissions as he's too busy and his quality of life is suffering due to the workload. Said he will be focusing on parts and aftermarket stuff instead.Cope quality and customer service has seriously gone downhill. I don't know if its true, but I just read he no longer builds trannies just sells parts. He did one for a buddy 2 years or so ago and it had wrong parts inside.
I would want to have a LU converter if possible to drop some RPM and save some fuel. But that's just me.One more thing. What about lockup? Is it worth converting to a manual lockup with a button on the shifter? Or will that complicate things too much for too little benefit? I saw some Kits that are around 1000$ but include the trans shenanigans that are needed...
To add to that -70s-mid-80s (roughly) transmissions had LU controlled hydraulically and the actuation RPM likely would not be ideal. I don't think modifying one of those to manual control will be very practical.
I pulled my trans out a couple summers ago. Just used 4 drive on ramps. Trans out in not much more than an hour.I have a fitech. Got that one when they first came out. I dont think its the sprag then...
Could one get the trans off under the car and replace the flexplate? How much ground clearance should I factor in? But to be real, i will probably just tighten it up now with a small spotweld on the bolt to flexplate and then do it right next winter. Meanwhile signing up for AAA haha
