You are watching: Will a 4l60e transmission fit a 350

So my TH350 is attract out and rather than spend money come rebuild it i would like to simply put the money in the direction of an overdrive trans. However right now I have actually a soft 350 in the car and also down the roadway would favor to execute an LS conversion. I dont pretend to recognize anything around transmissions however I am wondering if I purchase a rebuilt 4L60E have the right to I use it through my current 350 and down the roadway use it v an LS engine? also do they work-related with any type of overdrive capable shifter?

I think you need to have a spacer / adaptor to make this work-related to a 350/LS combo, I would certainly go come and also ask the question.Steve

The 4L60E will bolt straight up to her 350. :yes: friend will need some method to regulate the tranny though. The OD is electronically controlled, for this reason the "E" in ~ the finish of the 4L60. There space transmission controllers the end there, yet $$$.
Build: baby!


It wasn"t clean to me on your engine plans. If you have actually a 1pc seal 350, GM has an adapter that will let you operation an LSx 4L60E/4L65E tranny through the gen 1 and also gen 2 engine. Then you you obtain your LSx engine, it will bolt appropriate up. As stated above, any kind of of the digital tranys will require a control module. It provides you manage of the change points and also firmness and also other functions. Nice cool!!!

Not for this reason fast!

Excellent details gentlemen. Therefore the infectious diseases world fashion controller looks to be about $1000 i beg your pardon is nice steep however will it save me under the road? together in go the LS computer automatically control the E-series trans hence making the controller ns paid $1000 because that obsolete when I upgrade the engine?And tnblkc230wz friend are specifically right about my plans. I at this time have a Gen i 350/TH350 in the car and I desire to upgrade the trans to the 4L60E now, and down the roadway upgrade the Gen i engine to an LS series.
