Default 4l60 afl valve fix

ive seen 2 fixes for the infamous blow by causing various problems 1 by sonnax where you "ream "out the whole in the valve body that requires major money just for the tool. the other by transgo with a slightly larger valve i believe. the transgo cxan be bought online for about $40. is there any reasons to not buy the transgo. is it only a bandaid. i'm keeping my truck for ever so i dion't want to have to end up later going with the sonnax after all.

the transgo fixes the same problem as the sonnax, they just use different methods. i'm asking for a comparison on the 2 methods, if their both work, if they work equally as well as each other.

I would do the hd-2 kit as mentioned by lildevil. The sonnax setup is a little difficult for the do it your selfer and the hd-2 kit is easily done.

my problem is that i have no overdrive or 1st gear. i just got out from under my truck and i have 12volts going to the tranny via a pink wire. so i'm guessing it would be the afl valve. according to the sonnax website , this is the problem. is there a test to check the afl valve.

i am corrsct in saying that the transgo hd2 kit fixes the problem, right. now i can't find the kit that mentions the Actuator Feed Limit Valve. i have been reading so much lately trying to diagnose this i might have gotten confused.
i was going to get the hd2

SONNAX 4L60E PINLESS FORWARD ACCUMULATOR

TRANSGO GM 1993-UP 4L60E SHIFT KIT

TRANSGO GM 1996-ON 4L60E SEPARATOR PLATE

SUPERIOR 700R4/4L60E BILLET SUPER SERVO 4TH APPLY PISTON AND COVER

Corvette Servo kit for the 700-R4 and 4L60E Transmissions
just take care of all the problems while i got it open.

No dissrespect meant but you need someone to scan this thing with a tech 2 or good scanner and correctly diagnose it before you throw parts at it.

well i just got off the phone with dan from transgo. he was super helpful and cool. he told me its not an afl problem because it happens all the time. afl problems only happen when it warms up he said. he said there is something wrong with the valve body itself. he said it would not be voltage because it will shift automatically from 2nd to 3rd. so would it be possable that it just need pulled down and cleaned up. maybe new check *****. i can't find anyone locally that has a scan tool that will check tranny activity during operation.
