Hi i know a mechanic that is gonna help me rebuild my 700R4 and i would like to kmow what rebuild kits you guys use. Also if they worked good also should i go for a 30 spline too or stay with the 27.

 

Use the 30 spline, I buy my kits here http://www.makcotransmissionparts.com/4L60-700R4.html

 

If yors is a 1991, then it is a 30 spline. Go to https://www.700r4l60e.com/store/home.php?cat=19 This will give you a choice as to what you need or want here. Let me know if I can be of help? Dana

 

So my tranny is a 30 spline then so what kit should i get

 

Get the kit AHP35003RK-S1 from the first site listed for a good high power performance kit or 74009B-BS will probably be more than good enough to handle what your doing and use either one with shift kit T74171

 

By your experience are these trans hard to rebuild or easy. Also is that all i would need or what else

 

Call me tomorrow at 909 795-1876 and I will answer any questions you have on this. I will explain what kit and torque converter will work best for you. Dana

 

The mechanic told me he already bought all the parts to rebuild it from you r website that you gave he said he has used that kit on most high performance transmissions he builds, and that he has always been happy with also his clients.

 

if your mechanic is going to use pro built rebuild kit and he knows what he is doing,than u have the best rebuild kit out there PERIOD!!!!

 

Thats exactly what he told me about the kit

 

good working 700r4's are hard to come by with regular mechanics. Most of the time it takes a transmission builder with a lot of 700r4 rebuild experience to make a good 700r4 regardless of if the kit is the best in the world.

 

thats why i said "if he knows what he is doing "

 

i'm procharged too. a p600. tired of it though and switching to a big block. you apparently got it under control with the rebuild, but seriously a general tech doing your rebuild. PM me back after install and tell how it turns out. it does take better than average trans rebuild skills to get good 700.

 

yeah not sure if the op is meaning a general mechanic or he means a trans rebuilder ...or he is just using the word "mechanic" in general

 

He said he has rebuild transmissions before. Not sure if he is a expert at these transmissions though. I don't think he is specialist on transmissions, because he mostly does engine rebuilds. He just told me that he cannot help me out no more so i am gonna go back to save more money to buy a rebuild transmission
that sucks.
