At some point, daimler also went to a common architecture... check it on allpar.
The 41TE, 42/4/6RE, 41LE, and so on are based on the same internals. first number is 3 of gears, 2nd number is the "torque rating," T/L/R transverse/longitudinal/RWD, E "electronically controlled". basic designs are the same but with different shafts/splines/bearings to accommodate different ratings. Example, a 42RE is a 41TE with thicker shafts, turned "the right way" for RWD application. A 41LE is a 41TE with a longitudinal engine but still FWD. I find it amusing, therefore, when folks say in general terms that the, "41TE is horrible but the 46RE is a totally different unit..." Not really-- they share similar designs, though I'll quite agree that the in general the heavier-duty units seem to hold up better (excluding the early-2000's woes with the Rams.... that was a mess... but fixed after a couple of years if I understand it right).
I do wonder how much of the 41TE problems are from heat in minivan applications. Mine saw 220F yesterday in low ambient temps during some mountain driving. 180F is attainable year round on this trans (permanent gauge installed).
