So I have a 2003 Jeep Wrangler X, The park paw was broke. The trans would shutter and was in limp mode. Not sure if something got in it from Park Paw breaking damaging the transmission either way had to be changed. Found one That had 50,000 mi and was pulled because of hemi swap, Park. Paw works great but the Shutter is still there!!! changed ECM TCM same results staying in second gear shuttering when taking off which is a sign of slippage from taking off in second gear limp mode. Have the p0755 engine code obviously thinking corrosion or bad wire or bus Jeep is very clean. No rust all grounds were cleaned and resecured new to the Jeep thing. Is there any things I should look for first, any help would be greatly appreciated. Thanks in advance
