If it only happens in lock up in od.Anything more than an ez ,very ez, acceleration will make a stock converter shake. It just does, sorry but it's an expensive upgrade and even I didn't want to do it. I'm happy I did.
Belive what you want, this is a common issue.
Btw the more weight you put in it will increase the problem as the converter is flexing then slipping before power is transmitted to the wheels. A lighter weight truck won't run in to this issue as frequent.
Check your tps sensor, if it's out of spec it will pot the trans in od too early before there is enough line pressure. Tv cable adjustment could also affect these things but I suspect the tps if your truck goes to od before 45.
Search for the tps stuff it's all here.
The trans pump is making more line pressure at 45 but still not enough rpm for heavy acceleration to wot. Line pressure holds the converter tight... Not until 1600 or 1700 is there enough line pressure for wot.
The stock trans SUCKS even for a stock truck, even if it's new or rebuilt. It needs the beef! Your truck will thank you. I love feeling the torque down low instead of shaky truck...
At least consider a valve body and single billit torque converter and definitely check the tps, all you need is a multi meter and paper clip. Replacement tps is about 250 last time I checked.
Don't let this happen or you will be forced to correct the problem sooner than later. If you ruin your converter ,clutch friction material will get all up in the trans and soon the trans will need a rebuild. Not to mention if your truck fails to lock up the cooling circut will not engage and heat will continue to destroy the trans until it quits. We don't have trans temp on our trucks but even stock stock transmissions run the upper limit of acceptable operating temps.
Doood, I didn't see that you have a 3gsk and 10 plate, but the 3gsk changes the pedal/ fueling profile. Notice how you have to use less pedal for a response fron the truck? This correlates to the tps as well as line pressure relative to the amount of power the engine is making at a given rpm.
I had my 4gsk , fuel plate, and timing tools sitting in a box until I fixed up the tranny.....
I couldn't believe I paid more for the trans than i did for the whole truck! And I still plan on billet shafts later on,even then I'll sell the 47rh and do an Allison 1000 6speed. ( when I find a spare 10gs)
This gets pretty dam ridiculous. quick .
Why can't we just be happy with a 160 hp cool sounding truck....
