700r4 transmission upgrades how to#

The instructions inlcuded all the info I needed to improve the oiling, how to prevent front seal blowout, how to slightly BURN the band with the trans in the car to soften the hard 1-2 shift of a newer band, where to drill and what size drill to get 'RV' shifts or harder 'RACE' shifts. They also included the newer hardended steel rings for the oil pump to replace the stock type that break, a new 3-4 clutch pack designed to add more clutch discs, oil pump spring and relief valve for better oiling, and. They even included all the springs, pieces, and instructions on changing the valve body actions to cure all the factory shifting problems where to grind off a bit and where to put each new part. I believe I got my Transgo valve body reprogramming kit and their trans rebuild kit from NAPA. They will save you a lot of headaches, and teach you the important points very quickly and in simple easy to understand terms. This may have been an oversight on your part but they make a much better 'holding' one than OE.

700r4 transmission upgrades upgrade#

You mention all the right parts for a Hot Rod upgrade put you didn't say anything about the sprag. Simply put, It works! Also looking into a company called Sonnax for a complete list of upgrades.you are on the right track with replacing the ever breaking sunshell and getting the 'Beast' upgrade, so I think you can appreciate that the upgrades are proven and work. I have used this same kit with great success many times. I would encourage you to get this and read the complete instructions. I understand that the 700R4 pump has a problem with drainback issues and general leaks in this area, if not a complete seal BLOWOUT! TransGO makes a great system correction that covers this. You can fix these problems another way without changing the pump. You can get a special washer kit but there is nothing wrong with what you have if the pump specs out and not deformed somehow.

This is because that not all pumps with same part number spec out to exact measurements. There are a few more things you can do.The whole pump thing kinda scares me, you need to keep an eye out on a few things.first and foremost, endplay, the bronze type washer on the back of the pump is there for a reason. The Throttle valve cable will be your best friend/worst enemy.learn how it works in relation to the throttle on carb arm and you will have it whipped. A short shift is perfect, not harsh, not long and drawn out, it just happens and at the right time. A harsh shift is timing the clutch elements too tight,causing them to fight each other.the resulting 'bang' spikes the hard parts causing premature wear. Trans go has the best/smartest shift kit,realize that a shift is nothing more than a controlled slip.the longer the shift the more the clutches/band slips. If not high horsepower I didn`t use them.

Be careful about any clutch kits that change the number of clutches in a pack,what they do is use thinner steel plates to fit more clutches,heres the problem,the steels are the heat sink,no heat sink, burned clutches. You are on the right rack, the early units work just fine,you don`t necessarily need to change the pump but rather change the pump rotor and vanes to the later ones they don`t really make more pressure but rather more oil volume.
