Tell me more about this. Or do you have a link with more info?

I'm guessing a lot of people were curious? I can tell you what I know about the item but I haven't personally tested it.

Aparently much of the issue with torque converter shudder has to do with the time and amount of engagement. That is why many TSB'* call for recalibrating the PCM to delay engaging the torque converter. The item in question has a dial you can turn to delay the engagement thus effectively eliminating torque converter shudder.



This has its obvious benefits as there is a 6+ page thread somewhere on here talking about just that issue. Now I'm not going to sit here and say this is a fix for everyone there, but the theory works out.

They featured it on Shade Tree Mechanic a while back and it'* been around for a while. I haven't read any complaints about it either.

Aside from that since I haven't personally tested it I really can't say much else. I'm hoping to get that and the vacuum shift improver for testing and a writeup soon. If I get more info between now and then I'll let you guys know.

I've found a couple links with application guides. None include the Series I SC. Or will that even matter?

It'* the transmission that matters, they all look for the same signal reguardless of engine type. Many people only know what car they have, not the model of transmission.

I finally got one. But it don't fit, durn it. It has a 3 key connector, my car has a 1 key connector, so no workey. Anyone with a Series I wanna check theirs out, maybe snap a pic to see what you got, just so we can figure out what it will fit. Any L27 or L67?

Moving to 92-99.

That'* really strange, the place I'm getting it from says clearly for any year 60-e. I even wrote to them to verify. Strange....well I took it off my site till we figure out what'* going on with that. I'm going to write to them again with this bit of info and see what they say. I hope they weren't just after a sale and this can be explained with a different part # than what you got.

Just returned from a trip up and down mountains to Newburg N.Y.
Car used to chuggle under load on long mountains, it now pops out of OD for about (in cruise) 10 seconds, powers up to speed like a race horse, and re-engages. What a pleasure. It never did this until I advanced the TPS. The trans must use the TPS signal in abscence of the TV cable.
I also think the Trans fluid is crucial in eliminating this.

I've tested my TPS. It seems fine. Right now, I'm looking at cheaper alternatives to getting my tranny torn open.

I've had a recent flush, made damn sure it wasn't an engine miss, or EGR related.

will it downshift out of OD in mod to heavy throttle?

Yes. It seems to shift where and when it should.
