Question : 94 GTP-what years is the trans compatible with?

[no_doz]

i have a 1994 GTP with a crap title (odo discrepancy because my gf's aunt swapped clusters with one that had like 6-8k more miles than that car did, stupid!!) ive decided to part it out completely.

my question is, what all years/vehicles have a computer that would be able to control this trans? its the 3.4 DOHC lq1 with auto trans.

[robertisaar]

all 3.4 trannies had a 3.43 FDR, nothing else had that gearset. the 94 also uses PWM torque convertor control, something that only existed from 94-96 in the 3.4 4t60-e(since 97 was 4t65-e)

so any 94-96 3.4 tranny would work.

that's for if you want to swap it, but from your post it sounds like you want a tranny controller?

[no_doz]

nope-im partin it, just tryin to find out what years/cars this trans could go into with the stock computer controlling it.

so other than the torque converter is there anything stronger about these transmissions than the standard 4t60-e? & whats so special about the torque converter?

thanks for your help man

[robertisaar]

in that case, it's a direct replacement for any 94-96 3.4 equipped W.

the torque cinvertor is "special" due to it being a pulse width modulated convertor. it could probably be used in earlier models as well, but i won't guarantee it. connectors may be different.

[no_doz]

what about if the connectors were adapted?

[robertisaar]

i'm seeing 93 as having the same connector as the 94-up, but 92 has a different part number, but they are all 7 pin conectors, so it could be chopped off and a new one soldered on, or possibly just removing the pins and wiring from one and into the other.

[no_doz]

but would the 92-96 computers (auto computers) be able to control it just fine with the connectors adapted/everything properly wired?

[robertisaar]

of course. the 91-93 3.4 cars came with a 16149396 PCM that controls a 4t60-e from the factory.

if it's any indication, my tranny uses a PWM TCC and i'm running it on the 16149396 and haven't had any issues with it.

[no_doz]

what about the 3.1/3100 vehicles from 91-95?

[robertisaar]

3.1 cars didn't get the 60-e until 1993(W only), 3100 at the same time(late cutlass supremes only in 1993).

but they used a 3.33 FDR instead of 3.43. VSS reluctor is the same though.

[no_doz]

would it be possible to mate it to a 93+ w body without a controller, given the different fdr? if so what would be necessary?

as usual, helpful as hell

[robertisaar]

controller? the ECM does control the tranny... that's why i keep refering to it as a PCM...

the 3% difference in FDR probably won't make any major difference, but it should be considered.

[no_doz]

im just wanting to know for anyone who wants to know if this trans will work in their car without any major changes/modifications.

thanks for your help man, when i need to know electrical about these vehicles you seem to know your shit, whatever you're doing keep it up!!

[robertisaar]

im just wanting to know for anyone who wants to know if this trans will work in their car without any major changes/modifications.

i wouldn't consider changing just the connector a major modification, so any 4t60e equipped 3.4 car or any 3.1/3100 car with a 4t60-e and had 3.33/3.29 gears would probably be fine. it would change driveability a little bit, but shouldn't be anything serious.

if you should need wiring diagrams, let me know.

EDIT: assuming the mounts are the same. with a W, it's a guarantee it will work. other body styles may be different.
