93 tbi 350 to 99 4l60e

[Chevyman70]

I recently picked up a 4l60e from a 99 yukon and wanted to swap it to my 93 blazer. I know it should pretty much be a straight swap mechanically, but will the wiring match is my question? It was free so if its no good ill just sell it and use the money to fix my old trans.

your 99 will not physicall bolt in. it has a six bolt pattern on the case, IIRC all the S series used a five bolt pattern. There is a tiny wiring difference beyond that. 93-95 do not have a PWM solenoid and lack the wiring for it on the case connector. sell the late and pay someone to build your early.

Its not an S series, its a fullsize. But I figured as much on the wiring. Thanks

Still a no go, the rear of the trans cases are where the difference is.

Chevyman70, I may be looking for a 4L60 tranny for my 99 suburban 350 real soon. NOt 100% sure if i need a 4L60 or 4L60E though, while we are on the subject, can someone explain what the difference is between the 2 trannys?

u should need a 4l60e for a 99, a 4l60 is just a 700r4 that was used before the 4l60e the e just means it is electronically shift controlled. I think they started using the 4l60e pretty much exclusively in 97

4L60/700R4 Different than 4L60E <---Electronically controlled.

700R4 to 4L60E in late '94 and all '95 and up...

There is no 4l60... It's either a 700r4 or a 4l60e. E standing for electronic
