Re: [Chevelle-List] Four Speed to Automatic (ATTN: Kent)
GOT IT! I had a friend at work go see an engineer he knows that is a pack rat. Saved everything for the past 35 years. He's getting ready to retire and I sure would like to talk him in to giving me his stuff. We'll see. But this is what I've been able to find out. It's not much but at least you'll know something about it. Your trans was installed in a Chevy or GMC pick-me-up. It was backed up by a 350 c.i.d. engine. Probably 255 horse power with a four barrel. Hope this helps you. Very good trans and VERY upgradeable. A simple change of wave plates and a couple of other parts and you got a trans that will handle lots of power. If your interested let me know. I'll tell you what you need.

Re: [Chevelle-List] Four Speed to Automatic
You need to measure the tail stock of the new trans
then measure the tail stock of the one that came out of it and subtract the
difference. If the trans is in the car measure from the output shaft to the yoke
of the the differential and add I think 4".
The place you will measure the tail stock from is
the trans. mount where it bolts to the frame to the tip of the output
shaft.

Lojac,
The TH400 and TH700 are different
lengths.
You will need to shorten the drive shaft if you go
to a th700.Not sure of the length, people will tell you to "measure
your car".
The trans tunnel on thepass side at the
firewall will need to be dented in a bit for clearance with a TH700. Not a
big deal but a mod was required on my 1971.
The trans cross member needs to move if going from
a TH400 to TH700. There were existing holes in my frame I used. It sounds
like some frames have correct holes and some people can use one existing
hole and drill another on each side.
The TH400 trans cooler lines I purchased work on my
TH700.
If
you go from a three speed auto on the floor to a 4 speed, you can change the
console face plate and shift detent plate to one for the 4 speed. Year one
sells the kits, I think they are about $100.

RE: [Chevelle-List] Four Speed to Automatic
I do
not know if a TH400 and a manual trans are the same length. I started with
a 400 and went to a 700.
No
reputable shop will tell you the size of shaft you need :) Too risky for
them. They will tell you to measure from yoke center to yoke center and
bring them a number. They can make a shaft theexact length that you
specify.
IMO it
is not easy getting this measurement. I took mine while the rear
suspension was hanging. I measured three times but somehow when the shaft was
put on it is about 1" too short.Mine will probably work like it is
initially, but I intend to have the shop lengthenit or I will get another
shaft and have it shortened to the correct length. My suspension is fully
extended yet, with new springs, gas charged shocks, and polygraphite
bushings. If the back end sags or sits down a bit after some use that will
locate the drive shaft farther onto the trans output spline.
If you
found someone with the transmission setup you want, you could measure the shaft
on their car and it would probably be ok.
Good
luck.

Re: [Chevelle-List] Four Speed to Automatic
Lojac,Don't bet onnot massaging the drive shaft.The 350 and 400 came with a short and long tail shaft. The 350 WILL handle a big block but it has to be in good condition. But I wouldn't recommend it unless it was rebuilt for your application.And the torque converter must match the torque of the engine. The 350 has 4 multi - disc clutches and 2 roller clutches. The 400 is the best choice. It has 3 multi - disc clutches, 1 one-way clutch and 1 roller clutch, detent solenoid, and vacuum modulator to sense engine torque controlling line pressure. This alone makes it better over the 350. All torque requirements are met and you get the right shift points. Look for these codes on the 400 1968 396 - CA 427 - CB 396 - CC ( Chevelle/Camaro) 396 - CH ( high performance) 396 - CH 1969 396 - CA 427 / 390 HP -CB 396 / 325 HP - CC 396 / 350 HP - CE (Chevelle/Camaro 427 / 335 HP - CF AlsoCG, CH, CL, CQ, and CY and the famous 350 - 300 HP Vette..

If you have a code you can't figure out I'll be glad to help. I have worked at GM Hydra-matic for the past 28 years. If I don't know the answer I can find out for you. One last comment, and this is my opinion only. The 350 was and still is a great transmission. It just wasn't built to take the torque of the muscle era. If you want a trouble free cruiser it can't be beat.

RE: [Chevelle-List] Four Speed to Automatic
Lojac, The TH400 and TH700 are different lengths. You will need to shorten the drive shaft if you go to a th700.Not sure of the length, people will tell you to "measure your car". The trans tunnel on thepass side at the firewall will need to be dented in a bit for clearance with a TH700. Not a big deal but a mod was required on my 1971. The trans cross member needs to move if going from a TH400 to TH700. There were existing holes in my frame I used. It sounds like some frames have correct holes and some people can use one existing hole and drill another on each side. The TH400 trans cooler lines I purchased work on my TH700. If you go from a three speed auto on the floor to a 4 speed, you can change the console face plate and shift detent plate to one for the 4 speed. Year one sells the kits, I think they are about $100.

Rich, Yes, it is clearly a "CT". Maybe a truck or motor home ? (Just thinking out loud...) Kent '68 Malibu ZZ502/502 :) ACES #5102 Kent, are you sure that's a T after the C? I'll check it tonight at work. 69 is the year and 29731 is the serial number sequence. I don't list a CT. C is for Chevrolet. O for Olds, B for Buick, etc. I'll get back with you tomorrow.

Re: [Chevelle-List] Four Speed to Automatic
the driveshaft will need to be shortened for a TH400 swap. A 700R4 may or may not stand up to the torque of a big block, i have heard conflicting stories about that. The only other thing you will need to change is the pedals which is pretty easy. Other that its about a days worth of work. Tom
Re: [Chevelle-List] Four Speed to Automatic
Replies to this message are sent to The Chevelle Mailing List I haven't followed all the msgs closely , but IF you are going with the 400 - i believe that they have an electric kickdown system - hadn't seen any mention of that.IF you are going with a 700 - they have electric lockup for the torque converter. I've got links that may help with the wiring. 400 700 are close to the same length. If you need to shorten drive shaft for one, the other will need it too. A 700 can withstand a mild big block on the street, especially a mostly cruiser only.If you want to use tires that will hook you up, the 700 will not last too long unless its built by a pro. Post 86 700's are stronger than earlier years. rick schaefer 72 El Camino http://members.home.net/jimmy4/rick1972elky.html TPI 350-700r4 http://chevelles.com/showroom/ricks%20motor%20-L Team Chevelle # 0038 ACES #0140 On Sun, 24 Mar 2002 22:48:50 -0500 Lojac [EMAIL PROTECTED] writes: Is this an easy swap or complicated?

Re: [Chevelle-List] Four Speed to Automatic
what about the TH350? I will not need to shorten the drive shaft and this would make the swap easier. Will the TH350 handle a Big Block? What is the HP and Torque rating of a TH350 vs. a TH400. Is the driveshaft shortening a easy process for a machine shop to do Is it expensive?? Thanks for all of the feedback, Lojac - Original Message - From: Kelly C.

lojac: the bellhousing is part of the transmission larry (z)
Re: [Chevelle-List] Four Speed to Automatic
stay away from the th350 if you have much torque. i tore 3 th350 apart with a bb. went to a th400 and no more trouble larry (z)

Re: [Chevelle-List] Four Speed to Automatic
I am planning on rebuilding the engine and I am not sure how much torque I am going to end up getting. SO you say I should go with the TH400 eventhough I have to shorten the driveshaft. I was hoping for a little easier installation than that.

[Chevelle-List] Four Speed to Automatic
Can someone out there please tell me everything I would need to convert by 69 Chevelle from a four speed to an automatic? The car was originally an automatic, so I think there are still some of the linkages under the hood (???). I was thinking about a Turbo400...any thoughts. Anyway, I just wanted to know what I needed to do the swap. Does anyone make a kit for this swap? Thanks, Lojac
Re: [Chevelle-List] Four Speed to Automatic
column shift or floor shift? if its a column shift, then u need the linkage from the column to the tranny if its a floor shift then you will need a shifter, cable, range select lever, the column to tranny linkage for safety reasons, console assembly, console wiring, console mounts. If you already have a console then forget about all the console stuff, you will just need a new auto top plate. Hope this helps! Tom
