Hello,

I finally have the funds saved up to buy my LS motor and start my swap, my question is I already have a late 90's (around 97-98) 4L60E that was recently rebuilt before I pulled it out of the totaled car it was in. The place I am getting my motor from is willing to sell me a complete pull out (motor, trans, access., wiring, etc) for $1400 from a low mileage 2005 truck or everything minus the trans for $700. That is a fair amount of money to me at least and my question is how much different is the 97/98 4L60E and the 2005 4L60E? Would my trans talk to the 2005 computer or would I be better off just spending the extra money?

Thanks for any information,
Michael

The transmission will work with your 20o5 electronics.

Ask what the trans came out of ?

The electronics 95+ are the same but you will need the spacer (LS cranks are .400" shorter than SBC) and flexplate with proper torque converter bolt pattern to use an older trans with the LS motor

I made the assumption that the trans was out of a 98 Camaro/Trans Am. I appologize, will clarify (agree with Flame), if the trans is from an LS vehicle it will work. If it is from 95 or newer it will work as well since it has a PWM TCC function albeit it will need a spacer between the flexplate and converter.

That is why I asked the question on what it came out of.. could even have been a 97, LT1 F-Body, (or ?) which would require the Spacer/flexplate, Well you know the routine of using different miss matched years and models.

Yeah it's from an Lt-1, what's different between and ls trans and Lt trans? is it the bellhousing or the input shaft?

The newer trans have a removable bellhousing and the input shaft and converter are different. My LT1 trans has been behind my LS1 for a few years now. I used the flexplate and spacer from advanced adaptors #712500A.

My vote: Get the complete takeout. Sell the other trans.
The 05 trans has some improved components in it. [And, you won't be chasing spacers, flex plates, bolts, etc, etc.]

Depends if his current trans has been upgraded. If it is stock then I vote for the complete take out. Rebuilt with good parts then its up to you!
