2002 Silverado After a Transgo Kit

xjcamaro89 · #1 01-23-2008, 01:21 PM

Ok, i had the infamous weird shift in between 1-2 and 3-4 sometimes in my 2002 silvy 4.8 4l60e, but more than not, anyway, so after many researches on this board i decided to get a transgo kit and have it installed, so i took it to a trusted local shop and had it installed, they said everything they could see while they had the tranny apart looked good, they said the fluid looked good and everything. So they put it in and i still have the bump, knock whatever you want to call it every now and then in between the above shifts, not as bad, but i now am thinking its something else, like a u joint or something, so im not sure what is going on now.

did they check out the electrical connector at the transmission. some have had wierd shift problems because of damage to contacts in this fixture.......

Was the servo changed to the Corvette Servo? If not, were the seals replaced?

I couldnt tell you that or not on the seals, do new seals come with the kit for a 4l60E? If they do then yes cause they used everthing in the kit. And a no on the corvette servo.

No the seals do not come with the kit. Might be a good idea to pull the servo (can be done with Tranny in the truck) and make sure the seals look good or just replace them with a set of D-ring seals.

The band is applied in 2nd and 4th gear and the servo is what applies or releases the band. Since you are having issues with 1-2 and 3-4 shifts, the band being applied is common in these 2 shifts. The servo pin may be the wrong length or there could be an issue with the servo itself or with seals in the servo. Something to think about.

If i get a corvette servo is this something that i can do myself nothing that is as complicated as the transgo kit. and if i get a corvette servo is that all i need and does it just bolt off and on of the tranny. Where is it and what does it look like? is it on the pass side under the heat sheild, cause i was under there last night and pulled the heat sheild off and i was checking all connections on both sides of the tranny to make sure they were all fine and they were. Also what servo do i need exactly? thanks!

I'm beginning to think your shift problem is not the transmission.especially after the mod was done and the transmission shop checked it out.....maybe this shift is engine missss.......

I just changed fuel filter air filter spark plugs and wires, the engine seems to run fine. I might have the gap on the plugs a hair too big. But what could i do and i dont have any check engine lights

it is possible that the maf is the bad guy. someone on forum said to give the maf a tap and if the engine skips then the maf is bad. another is cold air intake mod in winter sometimes will give this type of problem.or maybe the maf needs to be cleaned if the little wires that sense air flow have just a little oil/road grime on them they will not report to the pcm the correct air flow.CRC maf cleaner works good to clean maf .if maf was never cleaned it should be now because of the mileage and age of it......

if you used platinum plugs I believe that gapping is not recomended.
the gap is .060 on my 5.3l but I did not have to adj this as it was correct out of box. if you took out plugs from engine and you found the gap incorrect then most likely as i found out the ac delco plugs the platinum chip falls off..................

I changed the gap on my plugs last night they were at .060 i changed them to .040. I cant really feel a difference, but not that i was expecting to. I have had to clean MAFs before on my blazer, it made all the difference in the world after i cleaned it, i did pull the MAF monday night and the MAF doesnt come apart like it did in the blazers and other cars. So i was thinking maybe just a spray of somthing through the honeycomb screen to clean the wires? By the way my truck is a 2002 4.8 with 59,000 miles on it, sorry i didnt post that before, but now i have to take it to the place where i got all new steel brake lines put on last week cause the two at the master cylinder are leaking. I had the rusty brake line blues!

you must remove the maf from the rubber duct this can be done with some dish soap and water in spray bottle , spray joints , warm removed ducting and the soap will safely lubricate the joint so it can be removed, then the wires will be visable for your maf spray. use small amount of vasoline to aid in the reinstallation of ducting to MAF only use approved maf cleaner other chemicals will destroy electronics imbedded in the MAF
