hi everyone, i started have trouble with my trans today on a long trip.
i can feel the trans shift from 1st to 2nd, than soon after that there is a loud bang from the trans, i was driving 60 mph at over 3000 rpm. if i kept that speed it started to run almost over 210*. if i slowed down to lets say 30mph the trans quickly cooled to 180*
now about the car, its a built 4l60e, with a 3200 vig. converter, and i am not using the stock cooler, i have the b&m cooler with a fan.
i checked the fluid level, looked ok, and fluid was pink and not burned.
any suggestions would be appreciated.
thanks

sounds like you lost your 3-4 clutches gear

if my a/f ratio was lean would it cause this? i changed my maf and was running lean, i just changed it back to stock.

What gears do you actually have 1-2-etc and what happens at each shift point

when i first take off from a stop, i can feel it shift, then thats followed by a thumping noise from the trans and thats it, i dont feel it shifting anymore even when i go up to 70 mph. the thump i was told its the tq converter, but dont know.

P0751 is a 1-2 shift solenoid code. The other codes are for you o2 sensors. If there is a loud bang i am going to guess there is a mechanical failure in the trans.

Like he said if there was a loud band not good But I would pull the pan and if clean replace the 1-2 solenoid to see what happens before I ordered a trans .

i talked to the guy who biult it, he says that bang is the tq converter.
i pulled the pan last week and replaced the fluid and installed a b&m pan.

how hard is it to replace the sol.? or should i just bring it back to him, the only problem is he is 200 miles away.

performabuilt

Well the solinoid other than removing the pan just takes a minute its very easy

replaced both of the sol. today, p0751 came back on twice, i reset it came back on exactly 15 miles later,

p0751- 1-2 shift sol. performance. i did some research people on here just tune that code out. is this ok?
i couldnt figuire out how to see what gear i am in with hptunners, so no clue whats going on.

When you are using the scanner just get to the tables display and remove something you don't need by first left clicking to highlight it and then right clicking to get a menu that has "delete" as a choice. Then you can add the "current gear" from the transmission\general table by left clicking to highlight a vacant table line and right click to select insert from the menu. When you see the "current gear" choice double left click on it to add it to the table. If you add too many things it will tell you it is limited to 24 bits of input.
