The auto tranny looks HUGE compared to manual ones - anyone know what kind of weight difference there is, or just how much each weighs?

I do not know how much the auto weighs, but I do know that the getrag weighs just under 100 lbs dry. Seriously like 98 or 99 pounds with no fluid at all.

The weight depends on how far you have to carry it.

I believe the Getrag waighs about 90-99 lbs. the auto probably about 130-150 cuzz i couldnt lift it for the life of me. the Getrag i could carry it no problem

Kinda off topic but maybe helpful. I just shipped a 4t65e? It is the trans that comes attached to a 3800 SC engine. It came in at just under 200lbs.

If you're going to just guesstimate how heavy the auto is just by lifting it yourself, you need to take into consideration the awkwardness of trying to hold it. There isn't a good spot to grab it =). But I'd definitely say that the auto has got to be somewhere between 130 to 150.

Well this is interesting - I've been planning a auto - manual swap and at the same time a front battery relocation, and it seems i will be getting a bit more weight redistribution than i'd thought! Cool. I'd read moving the battery shifts 2% of weight, so a 30 - 40 lb reduction in the back would be an even bigger change.

Thats what I am putting in my car and I have been picking up putting it on the dolly taking it off putting it back on. And I am a twig.

BEEEFFCAKE!!!!!!!!!!!!!!!! BEEEEEEFFFCAAAAAKE!!!!

The Getrag weighs about 90lbs. The 4t65e is about 200lbs and the Caddy 4t80e that's used with the Northstar is about 300 (295?) lbs. These are ballpark estimates from memory. Not sure about the Fiero T125. I would guess about 150lbs.

As a side note, when Dave put his ZZ435 in his 88 GT, he also swapped it from the factory manual to a Getrag. The net weight gain was estimated to be about 30lbs. I say estimated because he was comparing the weight of his completed V8 swap to a known 88 GT automatic that was similarly equipped, but didn't actually weight the same car before the swap.

I was just told my Fiero (the 85 SE with a v6 4 speed) was actually the lightest production Fiero made for that year and type of fiero.. hmm maybe when my fiero gets here we'll see what i can do on that auto cross thing here in hawaii
