I need to know what kind of transmission to go with my 51 chevy 3100. I see a lot of 700 r4's. I would like to know everyone's opinions, and the pro's and con's. I would like to have a reliable durable automatic transmission. What is the difference in the 700r4, and the 4l80, 4l60, etc. thanks
Tony Jacques

They changed the name in later years. Add an E at the end of the 4L60 making it a 4L60E meaning the transmission is computer controlled.
The 4L80E, no manual version, are all computer controlled and much stouter than the 4L60.
What motor and rear are you planning to run, and how are you going to use this truck? My guess would be the 700r4 is adequate for most applications, but without knowing how you intend to use the truck its not possible to say for sure. If you want to run a fully computer controlled system you need one of the -E types.

It's true. I really don't do anything but browse the Internet looking for trouble... | | |

They do an outstanding job of beefing up the tranny to whatever HP and driving conditions you will be experiencing. http://www.phoenixtrans.com/

Some AT trannys can be adapted to inline engines and most V8's will readily work. I think it is really difficult for anyone to properly recommend something without a lot more information. It would appear that you like the A/OD transmissions but do not say. The rear end will also play a part in the best choice. Is it stock or an open rear? What ratio? Some of the people here are pretty knowledgable and can help but they will need your input. | | |
