I have a couple of questions about the 700r4. First what hooks up to the 4 prong connector on the transmission?

Second what years are better? I heard something like the pre 88 wasn't any good is this true?

What would be a good shift kit? I want one that will let me really feel the shift.

Finally is there a number somewhere on the transmission so I can identify exactly which tranny I have?

Thanks

Brad

 

4 prong is lock up wiring
87 1/2 and up is better
b&m is my favorite, most prefer trans go
pass side of the trans, stamped just above the pan is a code used to decipher the info.

 

thanks for the help

On the lock-up, does it have to be hooked up? If I do what do I hook it too? I cant find anything that even looked like it came from it out of the car the tranny came out of.

Is there anything else I can put into the tranny to try to get it to perform better and last longer? Like a bigger TV valve or the Corvette Servo? What exactly do these things do? Can you even feel a difference?

Also once I get the number from the trans, Where can i go to cypher the number? Is there a list on here?
Thanks again

Brad

 

vette servo, .500 boost valve, hardened sun shell, kevlar bands, 9 clutch pack, modified governor, i could go on for ever.

 

Lock up should be hooked up. It is better for the trans and gives 2 or 3 mpg.
There are dozens of things you can do to beef up a 700r4. How much power you make and how much you wish to spend are relative.
Post the code and I will break it down for you.
Be sure that you have a 700r4. 16 bolts hold the pan on. It is rectangular, almost square and does not have any noticable humps or notches in the perimiter of the pan.

 

Can you break down my code? Qx%90$!=__%4Lbsa~~

 

Sure brutal,
qx= prototype
%90= January 1980
$!=_ extra low 1st gear ratio
The other number are internal Mopar codes.
