5R110
 

Alright guys I heard a long time ago that the 5R110 is in fact a 6 speed but only when in cold weather or something like that. Is this right or what?

The 5R110W, or TorqShift, automatic transmission is a redesign of the E40D/4R100. Basically, the gear ratio for first gear was lowered from 2.71 : 1 to 3.09 : 1. To get second gear the overdrive clutch is engaged to give a ratio of 2.2 : 1. Third gear is now the same ratio as the old second gear, 1.54 : 1. The TorqShift is advertised as being a 5 speed automatic, when actually it has six forward speeds. On cold engine operation (below 0 degrees) the overdrive clutch is engaged in third gear for a ratio of 1.09 : 1. The transmission will shift directly to sixth from fourth and fifth is skipped. On a warm engine the shift pattern would be 1st, 2nd, 3rd, 5th (direct drive), 6th.

Ah thank you very much. I thought it was a completely new tranny and nothing like the E4OD. But the 5R110's are great trannys! I would put it up against an Ally 1000 any day and I'm a GM guy.
