700r4 or 200r4

I have a 350 vortex and a 700r4 and get ruber from 1st to 2nd on hard take offs!! And i get 21 mpg on the Freeway. 3.74 rear end Can a 200 do that?

 

Yea, a 200 will do that

 

The 200-4R we bought from Phoenix in Weatherford TX shifts and works like a dream in the 32 3W Coupe.

 

I'm pretty sure that some 200r4's only came with a BOP pattern instead of the dual pattern like yours.

 

Are you sure it's a 200r4 and not a different 200, like a Metric?

 

MPG..

i forgot..

I am pulling down about 18mpg but I have the proflo injection setup on the rich side ;-)

 

I have a 200R4 that has a KTF on the tag in big letters, then 108-891KTF0445. It is supposed to be from a Cadillac Fleetwood limousine but I haven't been able to find numbers to verify that. Can anyone verify that?
Thanks.

Nothing wrong with that T350 - most reliable of the three !

 

I was talking to my transmission guy the other day and he told me that he uses the same parts in rebuilding a 84 as he does a 87 700r4.

 

My 200r4 is bolted to a 72 Chevy 350 mock up block and was supposed to have come out of a mid 80's Cadillac.
there is a casting no 8639224 on drivers side of case and the tag no is 111-881KTF02-25.

 

I had the 200 in my 64 Bel Air with a mild 350 and it didn't last any longer than about 8 months and pulling it out 3 times for multiple problems. I don't think I had to change the driveshaft yoke but I know I had to move the cross member when going from a Powerglide to the 200. The 200 was designed to be light and used with V6 cars. The version used in the Buick Grand Nationals is a different set up from what I understand. I swapped out the 200 for a 700R4 and it's been in the car with over 100k miles with no problems. Spend a little more and eliminate a bunch of trouble.

 

Most of the parts out there to rebuild the 700R4 from manufacturers are superseding the old design parts. If I recall correctly, 87 and later parts can be used in a 84 trans but not the other way around. 87 and later 700R4 units are the better way to go as gm worked out some of the issues the earlier units had plus the new updates they have for rebuild parts make it a good unit to use. My 700R4 has been in my 64 Bel Air for over 10 years and 100k miles with no trouble.

 

I also forgot to mention that the later units had an auxiliary valve body that the older units didn't have. I could be wrong but I think the auxiliary valve body had something to do with cushioning the clunk when put into gear. Been long ago since I have been into a 700R4 and remembering all of the intricacies becomes difficult.

 

I drive a steel Deuce roadster with the following: Stock Vortek 350, 700R4, 3:73 positrac Ford 8" dropout, and 31" tires. At 75 mph, it tachs 2050 rpms, and as light as it is, it comes out of the hole plenty strong. Just my $.02. I want to install a 200 4R in my '40 sedan, but I have heard that that trans costs thousands to make it 700R4 worthy. The 200 will fit in the stock '40 frame with minimum cutting, and that is what I'm looking for. The trans man who has rebuilt all our automatics in the club wants nothing to do with the 200. Please clear this up for me. The '40 is going to be a long-distance cruiser like the Deuce. Thanks a lot. By the way, the Deuce gets an honest 22.5 mpg with its setup, and I want the same thing out of the '40.
