Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.

Usually if the engine is running and revving up good and strong in park or neutral but bogs down and shifting issues in some cases when in drive or reverse this can indicate a transmission component at fault.One of the most common causes I have seen several times before needing replaced is the transmission torque converter itself.It can stay partially locked in place and cause this exact fault here.

If you have not had the fault codes checked to see what codes are set this needs done.If any are set the codes will need diagnosed to locate and correct this issue here.If no codes are set the transmission components mainly the torque converter will need tested to see if it needs replaced.

If more help is needed, use the reply tab to continue our conversation. If no further assistance is needed, kindly rate my service,your 5 star rating is appreciated.You can rate at any time and we can continue to work on your question as this will not close out your question.Keep in mind in some cases it can be difficult to fully diagnose or help repair your vehicle without seeing it and I work on delivering the best possible answer from what I see to work with.

Thanks Pete

Thank you Pete......... will read the codes when I get home tonight, check trans fluid levels too, and already have purchased fuel filters, so I will be doing that job tonight. If I am stumped..... I will check back. If not, I will certainly complete the ratings with maximum stars. Hang in there, and thank you so far. - PH
