Toyota seems ready to switch over to CVT, with their Hybrids, and since they are the pole-setter, I think a 9 or 10 speed would be a waste.
Not that someone won't do it. Because someone will.
Where do you draw the line? I say 8-speeds.

Well like you old, old, timer's bikes 10 speeds might be the limit. I would still like to see a 18-speed manual like the Semi's I use to drive.-grin

...with my old-fashioned 4-speed automatic in my 1988 Buick Park Avenue. I shudder to think what the repair/replacement costs of an 8-speed tranny would be. Of course I would see a lot of children of trans techs going to Ivy League schools.

On those GM 4 speed autos !!!!!!!!!!!!!
My new 6 speed Chevy truck is one busy tranny!
We will see how it holds up heavy towing or snowplowing..
I note the many complaints on the camrys new trans.
But the toyo faithfull non owners are telling the poor
folks with issues that they are either crazy, troublemakers,
Some folks are never happy no matter how many useless
speed trans. are in a passenger car !!!!!!!

cvt's are not as fuel efficient as hoped for. the prime reason for going to more speeds is to improve fuel efficiency and performance. I don't think that GM's six speed will be that much much expensive to repair and with more gears the transmission fluid may stay cooler if the torque converter does less work. I think that to get six speeds there are probably 3 planetary gear sets. Probably 7 or 8 speeds can be made available from 3 planetary gear sets, so an 8 speed transmission would not have to be that much more complex.

...I'd rather just stop at 4 gears. More gears = more $ for the transmission shop guy! It already costs a minimum $2,500 for a tranny repair these days. I wonder how many more $ it takes for each added gear? Does it add or multiply?

I think sometimes it just depends on the transmission. I remember back in 1998 when I bought my '89 Gran Fury, from a place that refurbishes old police cars and sells them to the public, they told me that it cost around $1800 to rebuild the 4-speed automatic that late 80's Caprices were using. However, this wasn't the lighter 200R4 tranny (like what's in your Fleetwood, or my old '85 LeSabre) but a beefier tranny. I think it was the tranny that ultimately became the current 4L60E truck tranny. At that time, it would've cost around $650-700 to rebuild a 3-speed Torqueflite like what the Gran Fury had. And used ones were a dime a dozen, simply because they rarely failed, so there were plenty available out of junkyard cars. They told me that if the tranny ever failed, they could put in a used on for around $300!
One of the managers at work here had a 1987 Buick Electra Estate wagon with that lightweight 200R4 tranny. He had to have it replaced at some point, but I forget how many miles it had on it. He did a lot of towing with it. I think it cost around $2200 to replace, but he had the dealer do it, which probably inflated the bill.
Last tranny rebuild in my family was my uncle's 1997 Silverdao, back in the Spring of '06. It has the 4L60E tranny, and it started to fail. Reverse went out, along with 2 of the 4 forward gears, but I forget which two. It was around $1860 to have rebuilt, at a local tranny shop.
I've heard that the 4-speed they use in cars, like your '88 Electra, are actually fairly inexpensive to rebuild.
