The Early 3650's didn't have a reputation for being great shifters. The 1-2 clunk TSB being a notable complaint about them. I had an '03GT, and those first few 1-2 or even 2-3 shifts on a cold AM were cringeworthy. No idea if the issue was corrected in later versions.

Strong trans though.

By MY2008 they seem to have eliminated those issues, but the semi-remote-mounted shifter caused high-rpm shifting issues. Aftermarket shifters could improve but not eliminate this if the intermediate link between the shifter and the rail had worn.

Strength isn't an issue with the 3650 for a NA 4.6L 3-valve but the steps between 2nd and 3rd, and between 4th and 5th are really too wide for that engine. Gear spacing and eliminating the semi-remote shifter is why I am somewhat interested in the TKX. It's a considerably less expensive alternative to the Magnum XL.

IIRC there was exactly one, and it lives in the Corvette Museum (lived, if it was one of the cars they couldn't restore after the sinkhole event).

That one survived. Fortunately.

Last remaining 1983 Corvette gets dedicated display

I was told it fits just like a TKO!

For those running a TKO - is the stifflers TKO spacer needed to do the install ? I have their cross member. Thanks.

I just read an article on that and the cars that not restored were all saved and are shown as is.. Glad to hear they were not scrapped....

I don't know about other retailers but I noticed today on the Modern Driveline site that shipping TKX for Fords have been pushed back a month. I guess GM units have already started shipping. Ford units were supposed to start going out mid-late January, now it says mid-late February.

I installed the Stifflers on mine in April and didn't need the spacer kit, it put it against the tranny tunnel. You are talking about this one right?

Stifflers Mustang TKO Install Kit For STF-TCBM03 & STF-TCBM01 (82-98) TCB-TKO

Use this TKO install kit to get your TKO transmission installed onto your STF-TCBM03 or STF-TCBM01 crossmember.

I have that spacer kit and don't need it. Tranny sits fine without it. The top pic is tranny tunnel with spacers between the tranny and the mount, the second is without the spacers which is good. The bottom shows the stifflers crossmember with the metal shims, worked out good. And what is nice about the TKX for a lot of people is that it doesn't have the mount on the tail shaft for a torque arm. I'm either doing a 6 speed or a new TKX

 

[Striker01]

Which trans is this ? Tko ?

TKO 600, I was just saying the TKX doesn't have the torque arm mounting points

I have mine on order thru APW. Tremec is dropping the ball on deliveries. Don't know if its because of production line issues or covid (apparently T56's havent had an issue?) GM units started arriving last week, when i called last Friday APW was hoping to start receiving Ford boxes around the middle of this month but considering it was originally supposed to be shipping at the end of November..... I'm #7 on the Ford list and she said they usually get ~12 in at a time so I should be in the first batch. Last piece I need to get the car back on the road again (again)

 

[Striker01]

I don’t know if I should order mine now in order to get it for may?!

I was told by American power train that they are having production issues. Maybe there’s lots of parts on it from China?

Material shortages are global right now. I’m not surprised. I’m managing this within my own vendors and supply chain. Lead times are long, and costs are starting to creep up.

 

[Striker01]

They told me summit will be shipping out next month. For what it’s worth.

I asked Modern Driveline today and it could be as late as mid March before Ford units start shipping.

How do you like the stifflers crossmember? I have looked at it and the one that American Powertrain sells... Not sure yet which to use on the TKX upgrade.....

I just got mine an hour ago. Looks like a nice stout piece. Hopefully the install is straightforward and no issues with exhaust clearance

I like it, lines everything up nicely. Haven't had a lot of drive time with it though.
