Transmission Not shifting

[J_MLR3]

Hi,
I have a 2005 LR3 HSE with 108,000 miles which has intermittently begun to not shift from 4th to 5th once I reach cruising speed when entering a highway (55mph to 65mph). I can get it to shift if I enter sport mode, then I get out of sport mode and it stays in 5th and even shifts to 6th pretty quickly. It's the shift from 4th to 5th that it won't do automatically. Anyone out there experience this as well?

Thanks in Adavance!

The problem is an internal problem in the transmission. You'll need change the transmission but the Megatronics is probably ok.

Try a double gear box flush and filter , and a doctor tranny additive, works every time , [emoji106]

Same thing happened to mine. The transmission will most likely need to be rebuilt or replaced. The E-clutch had burned up
