4l60e trans question
My original problem with my trans was I only had 1st, 4th and reverse. Took the trans apart found that the 3-4 clutches were burn. So I decide to rebuild the trans myself. Install the trans back in the truck and took it for a road test now I have a different problem. After the road test I noticed that I don't have 3rd or 4th gear. What else could the problem be all the clutches and seal are new and I air check the 3-4 clutches before I install the input assay back into trans

re: 4l60e trans question
When line pressure test is peform what will that tell youI don't understand that test. I think I found my problem not sure the 3-4 clutches could have 5,6or 7 plate there a possible that i left one out .Will this cause no 3-4 shift .

A low pressure check would indicate an internal leak? caused by possibly a torn or damage seal?? NO or low pressure= no clutch apply! as far as the question on whether or not you left out a clutch? a clearance check should have been done when it was assembled? Too tight=burned or binding clutches, too loose= no clutch apply or slipping? |

re: 4l60e trans question
the clearance for the 3-4 clutch pack should be .050 to .070.
If you did not verify this and there is TOO much clearance the clutch pack cannot apply & there will be no 3 or 4th gears

re: 4l60e trans question
the clutch pack clearance is measured just like any other clearance.
perhaps a camparo to a engine valve / rocker arm clearance check would give you an idea of the process of checking clearance in the clutch pack

a book would be helpful since this appears to be a case of replacing parts in the tranny , not rebuilding it. There is a difference. On the flip side , I have read on this board that there is no Voo Doo to rebuilding automatic trannys.

re: 4l60e trans question
I have a book this is my first trans rebuild there was something that I did'nt understand . Took the trans apart again found that the tran kit that I order has performance clutches and the steels in the 3-4 clutch pack has a smaller thickness then the oem oneswhich requre you used more clutches. I remeasure the clutch pack clearance now I understand. Reinstall transmission now it shift into all the gears . Thank you

having a book helps. You did not mention the year of the 4L60E ( or I did not see that) , If it is a PWM lock up system for the torque converter , you would ahead of the game to do add some TransGo parts to correct a PWM problem that 90% of the 60E trannys develop

1995 was the first year of the PWM lock up system in the 4L60E. The current TransGo parts are a new valve and spring for the PWM system. Early TransGo was a new valve and dual spring setup that re-used one of the OE valves. IF you have a SRTA 4L60E v-body it will be stamped with SERV on it. Then you need a different kit from TransGo since the PWM bore will be larger from boring it out to repair the worn areas
