This has happened a few times before only I would loose reverse also. Cleaning the trans filter would take care of the problem. After the last time I cleaned the filter i shifted into drive & there was a couple second delay then it would engage into gear. Then one day the transmission stumbled after I stopped & started driving again. This is when I lost all forward gears. I tried cleaning the filter but the problem remains & reverse works fine. Could it be the shift solenoids?
You can only perform certain tasks yourself on a transmission. In this case it sounds like you need to visit a transmission shop. On occasion cleaning the oil and filter, making sure the trans is upto the correct level on fluid, may resolve an issue. If it does not then you probably need professional assistance.
You shoould visit a good independent rather than a lexus specialist as they will almost certainly charge an arm and leg for labor
GOOD LUCK

You sould have been moore frequent on your transmission fluid changes, and you shouldn't have taken it to Jiffy Lube either. Your best bet is to drain and fill the trans fluid run it shift gears. Drain and fill again. Do this 3 times. Yeah the transmission fluid is expensive. on the last drain and fill you want to get a bottle of LUBE GUARD from NAPA or who ever sells it. put the whole 10oz bottle in. Shift Rev, 1, 2, 3, D. Neutral Rev D. If that don't work then you have bad seals.

thats is normal for almost all the toyota's
the trans has to get to operating temp before it starts to shift normal.

Well, first do the service. Pull the pan down and look for metal shavings. If there is metal shavings your in for a transmission. If not, you may have a problem with one of the transmissions shift solenoids located near the valve body.
P.S. The Duramax has the Allison 1000 transmission not the dodge cummins and they are one of the best trannys on the market.

How many miles? Have you maintained, serviced trans in past or just waited for this day to wonder what happened?
