Questions - maybe problems.

Quoting Cyto - 'The tranny problem isn't on my top priority list, unless it's a quick fix. I'm swapping it with a W58, out of a 89+ model black supra i found up the road from my house'..Sorry guys, don't know how to highlight user comments.. Your car came stock with a turbo right? Any other solution than downgrading your tranny to the W58? Unless somethings been changed you should have the R154 tranny which is way better than the W58. If the one on your car is that bad perhaps getting that car for cheap is the least inexpensive way for repairs I suppose, and you've got a parts car lol.

I'm not sure if it's the W58 or not.. Just guessing..

Even if it does have it.. I like the gear ratio in the W58, it doesn't require modification.. and I'm not running anything higher than my CT26 right now. If my funds will allow me to turn my 7m into a god, I'll switch to the R154.

I got the tranny codes: 42, 61, 62, 63

I thought the GTE's A340E had a different end gear than the GE's A340E... not so?

To the best of my knowledge the only real difference is the number of clutch packs, with the GTE A340 having more of them to handle the increased torque. I thought all the gears were the same in the A340's, but I could be mistaken.

I meant I thought they had different differentials.... I don't know how they might change the internals of the transmission in this case (if at all)... I don't know much about auto's but am curious.

Yes, they did have different diff's with different ratio's. GE's I believe tended to have the 4.31, with GTE's carrying the 3.7 or 3.9.

Aside from the greater number of or heavier clutch packs in the GTE's I don't think there were any other significant differences in the transmission itself. But beyond bits and pieces of info I generally try and stay away from transmissions and transmission problems... way above my knowledge or pay scale.

Yeah, I just looked it up too. 4.30:1 in all MA70s (auto or 5 speed), 3.91 in all pre89 MA71s and 3.73 in all 89+ MA71s.
