1967 Imperial 727 shifting late

[moper]

The issue is not only the lack of spring (which will effect upshifts under light throttle) but the position of the stud the linkage is on. It's too close to the centerline of the carb shaft, so the travel is not what it's supposed to be to maintain the factory feel and performance. Your conversion guy screwed it up.

I must disagree with not adjusting the bands. The kickdown band it the hardest working piece in the transmission. It's job is to grab a spinning drum at speed and stop it solid anytime the trans shifts to second, it will do this till the adjustment gets so loose the servo piston fails. The low reverse band (adjustment inside) is not as critical for operation but if let go too long same basic nightmare till it cocks over in the bore or drops the strut and car stops when second gear comes on. A once of preventative maintenance is worth a pound of $$$$ toward a repair.

Propane conversions are not that foreign in the US. You might want to hunt around for parts. I'd bet there's a setup from a Dodge truck with the right bracket...

As screwed up as his throttle linkage is, he needs to concentrate getting that fixed before anything. THEN HE CAN WORRY ABOUT THE BAND ADJUSTMENT.

Your right but he was mentioning removing the pan for a filter change and the bands should always be adjusted when pan is off. The band adjustment will not fix his problem, sorry if it sounded like it would. I agree it is in the throttle linkage.

The correct spring might be in the restoration parts vendors' selections, I suspect. Just have to find an online catalog with them in it.
