Jetway has clutch/band issues(330ci) and I have a VP400 sitting from my Delta build(425ci)...the long tail will cause me to shorten the drive line. Aside from making sure to balance after cutting, are there any issues that can arrive from this swap, also which converter would I use?

 

The converter from the jetaway works great in the 400, I'm using one in my VP 400. You will need to move the crossmember back. The shift linkage works perfect, the cooling lines bolt right up, the switch on the throttle linkage works the same and wires right up. Does your trans from the Delta have a speedometer provision on the tailshaft?
Pretty easy swap I thought.
I used a 65 Delta trans, but changed it to a short tail and used the driveshaft from the Delta which was the correct length. I also used a much later valve body. I like mine. I used a flexible fill tube/dipstick from Milodon I think, I know it is not Lokar.

Good luck, Mike

 

A shop I work with charged me $200. and another $160. to cut and balance drive line. We used the converter from the 425 and moved the cross member back...everything just plugged in and no problems arose at all.
WOW what a difference...responsive and winds nice!! Turns out the trans we pulled was not a Jetaway but a ST300VP, not sure what to do with it?

 

For the 1964-1969 model years, "Jetaway" was simply Oldsmobile's marketing name for the Super Turbine 300 two speed trans.

 

Thanks Joe...my trans guy knew it as a ST300VP, I told him it was a Jetaway...he does not agree "they are not the same trans" says he.

 

Yeah, I has that argument with Norm here a couple of years ago. Olds used the Jetaway name on an automatic in the 1950s - that's the one he's thinking of. Olds recycled the name for the 1964-69 ST300 also. Look in your Chassis Service Manual - it clearly calls the trans a Jetaway.

 

should've been named the crawl-away. i never had one fail though.

Personally, I call the 64-69 transmissions ST300. That's what they are when they are in buicks and ponchos. They look a lot closer to th350's than how actual 50's Jetaways look so It's easier for me to teach people with the number designations.

 

Are they all variable pitch...or is this an orphan?

 

Olds versions were switch pitch

 

I have this 300 switch pitch baby and found the electric kickdown kind of cool. If it's working properly that is.

Buying the car, the seller explains these "Powerglides" have no kick down so, just move the lever when you wanna go fast. Sounded plausible. When I' start poking around her, I spot a curious, round device connected to the throttle linkage. I discovered it used switch contacts routed to the trans. One for idle maintaining through quarter throttle and another contact that closes at WOT. With this great site and the IntraWeb, I verify my Powerglide is indeed a Jetaway. Just the name implies an upgrade right there!

So, a quick continuity test reveals my swapped Old's, 350 Rocket donning an Edelbrock carb is not closing the switch contact point when she's wide-open. No electric kickdown for me? Nope, B&M makes a switch that mounts to the carb base and is adjustable for the trigger point. Sweet, I set it up to trip kickdown at the point my secondaries were starting to open. Road test proves dandy where now she loves to switch pitch when you stuff the gas. And yes, it Jets-Away. Sorry.

Okay, something of interest here is the switched torque applied by selecting different converter fluid paths from the solenoid position. Low pitch needs to be engaged to have good off-the line response. If your switch -pitch is being a Bit-ch, your take-off may be slug city. Throttle switch contacts must work from idle through mid throttle and the solenoid must be good for the low range function to work.

A true three speed is a bonus for lower 1st gear take-offs but this little slush pump seems fine to me. I like is the kickdown where the additional "boost" is just right and works predictably. Imagine if I had never looked into this? No Jetaway for sure.

Pretty neat for 1967 technology.

 

I enjoyed my SP trans with the 330.

 

^^ I like your car. I used pics of it selling my wife on grey wheel spokes.

The bling king selling my car had 20" Foose wheels on it. Ugh! I couldn't bear to drive it like that. Looked "Donk"-ish and hurt the buyer experience. So, I talked the seller into keeping his chrome, buck-board wheels and I'd show up with my own.

I wanted a similar look to your old-school and ended up with polished 15" Torque Thrust II's with BFG T/A's. Couldn't get the grey spokes quick enough for the purchase. Just saying your car helped inspire mine. So thanks!

Now if people would just stop asking me: what year GTO is that?

 

Thank you for the compliment and I'm glad it helped your wife with her decision. My wife has no vision and this one had a lot going against it up front according to her.

Here's a pic.
